Cement Based Materials

The construction industry has a significant environmental impact, contributing considerably to CO2 emissions, natural resource depletion, and energy consumption. The construction industry is currently trending towards using alternative construction materials in place of natural materials and cement, thereby reducing the environmental impact and promoting sustainability. Two approaches have been used in this review: scientometric analysis and a comprehensive manual review on the waste glass (WG) utilization in cement-based materials (CBMs) as a sustainable approach. Scientometric analysis is conducted to find out the current research trend from available bibliometric data and to identify the relevant publication fields, sources with the most publications, the most frequently used keywords, the most cited articles and authors, and the countries that have made the most significant contribution to the field of WG utilization in CBMs. The effect of WG on the mechanical properties of CBMs was found to be inconsistent in the literature. The inconsistent effects of WG impede its acceptance in the construction sector. This study intends to shed light on the arguments and tries to explain the opposing perspectives. This article summarizes the findings of various research groups and recommends new viewpoints based on the assessment of fundamental processes. The effect of utilizing WG on fresh and hardened properties of CBMs, including workability, compressive strength, split-tensile strength, and flexural strength, are reviewed. Furthermore, the microstructure and durability of composites containing WG are investigated. Different limitations associated with WG use in CBMs and their possible solution are reported. This study will assist researchers in identifying gaps in the present research. Additionally, the scientometric review will enable researchers from diverse regions to exchange novel ideas and technologies, collaborate on research, and form joint ventures.

The construction industry faces a challenging situation in attaining sustainable development goals. The carbon footprint of the production and use of construction materials such as the use of ordinary Portland cement in concrete products is still on the rise despite of many alternatives and technologies. In this paper, the local cross-organizational learning approach (COLA) and a systematic review of academic and professional literatures were applied in analyzing the use of fly ash as a geopolymer in the Philippine construction industry. Three primary stakeholders were considered: academe, professional organizations, and industry. Documents from each stakeholder were collected, with keywords including sustainability, fly ash, and geopolymer. These documents included published materials, newsletters, department orders, codes, and policies. Text analytics throughout the documents were applied using the Latent Dirichlet Allocation model, which uses a hierarchal Bayesian-modelling process that groups set of items into topics to determine the maturity level of the organizational learning. An adoption framework is proposed aligning COLA with the awareness, interest, desire, and action (AIDA) funnel model. Results show that the organizational maturity until optimization of academe is sufficient towards interest and desire, while industry is highly encouraged to increase organizational maturity from managed to optimization towards desire and action. Factors such as organizational intelligence (OI) and organizational stupidity (OS) are to be considered in balancing critical thinking across organizations. Further studies are recommended by considering the use of COLA with ASEAN organizations in the development of sustainable construction materials.

The persistent reliance on traditional construction materials is of no gain to the future generation. The rate at which the natural aggregate sources are explored is alarming, and as a result, the threat of depletion of the natural materials has inspired interest in sustainable construction materials, focusing on construction and demolition wastes and local materials. In this study, an experimental insight on modified concrete, based on workability, strength and microstructural properties, is provided, in an attempt to ascertain the suitability of silica-rich aggregates (ceramic industry wastes and laterite) as a replacement for conventional fine and coarse aggregates. Various mix proportions were considered, and material batching was done by weight for concrete casting. The workability test, using slump, indicates that the flowability of the modified concrete mixes is achievable at a water-binder ratio of 0.6. The strength properties of the concrete increased with the increasing ceramic substitution for granite while increasing laterite content beyond 10% negates the strength gain by the concrete. A concrete mix containing 90% ceramic fine and 10% laterite, as fine aggregate, and 100% of cement and ceramic coarse, as binder and coarse aggregate, respectively, gave higher compressive strength (22.5 MPa), and split-tensile strength (3.6 MPa), and these results were found as comparable to the conventional concrete.

In the recent years there has been an intensification of policies on sustainable construction materials in the construction industry. This environmental policy has brought about development of various sustainable materials in which Petrovege blocks is one of the outstanding products. This paper investigates the effect of curing age on the compressive strength of the product. Block samples were prepared by adding 8%, 9%, 10%, 11%, 12%, and 13% liquid content of the mixture of vegetable oil and crude oil sludge as a binder after the optimum liquid content has been established. The specimens were cured at different period of time of 48hrs, 72hrs, 96hrs, and 120hrs. Mechanical properties of the products were evaluated. Compressive strength of Petrovege samples varies from 5.31 N/mm2to 18.88 N/mm2indicating that the compressive strength increases with increase in curing age, while decrease in porosity leads to increased compressive strength for the stipulated curing ages. All samples satisfied the minimum requirements in terms of compressive strength, in accordance with all available standards.

The concept of sustainability has been growing for many years. In parallel to this popularity, the use of sustainable materials in the construction industry has increased significantly. Sustainable construction materials should be proposed and introduced to the construction industry, mostly as a replacement for cement. Cement is one of the most commonly used construction materials, which produces very high carbon emissions. As the most widely used building material in the world, concrete is predominantly comprised of cement. Therefore, sustainable alternative constituents to cement are required. This study focuses on alternative materials to cement and additionally, alternative materials to naturally available aggregates. The physical, chemical characteristics and mineralogical properties of the proposed materials are investigated and the results are demonstrated in this research study. The findings highlight the environmental and economic potential of replacing cement and other binding materials with steel slag.

Average Compressive Strength

One of the major causes of an increase in the consumption of resources is the progress of the construction industry. Although it leads to new technologies, it heavily contributes to global warming. In this study, the use of sustainable construction materials from waste in brick production with mycelium as a binder is investigated. The ability of mycelium, the root fibers of fungi, obtained from microorganisms is used as stabilizing and binding material on bricks. Forty-eight brick specimens from six design mixes were produced with a size of 200 mm length × 90 mm width × 60 mm height. The mechanical tests conducted were compressive and flexural strength. The changes in weight were recorded against its age to monitor the progress of mycelium growth inside the brick specimens. From the test, bricks made from sawdust and rice bran with mycelium had an increase of 31.0% to 38.5% in average compressive strength compared to the non-mycelium bricks, respectively. Furthermore, the bricks with mycelium experienced an increase in both flexural strength and midpoint displacement for all types of bricks (rice bran, sawdust, and clay). These mycelium-induced bricks can reduce the use and consumption of traditional construction materials with enhanced mechanical properties.

Abstract3D printing (3DP) is considered as a promising technology in construction industry due to a number of advantages that among others include fast and accurate construction, as well as elimination of formworks and material waste. Although 3DP technology is at an early stage of adoption in construction industry, its positive contribution towards a more sustainable construction approach is well acknowledged. Nevertheless, various constraints prevent its further establishment that include among others lack of knowledge among construction actors, premature investigation regarding techniques and material properties, as well as limited work on design optimization, cost, and environmental impact performance analysis. This chapter aims to contribute towards this direction by analysing the 3DP cost and environmental impact of a number of brick units, forming walls with different geometrical complexity. Results show that while walls’ complexity is increased, there are no significant changes in cost, global warming and primary energy consumption. In contrast, through the application of traditional construction processes, the result values would have been increased proportionally to the degree of complexity. This proves the potential of applying the 3DP technique to the construction of any structure at no extra cost and without increasing the environmental impact. Also, it provides an indication of its potential to be included within a regenerative construction framework.

The discarded object dart during alumina extraction from bauxite ores in Bayers process is Red Mud. The solid/ liquid insoluble by-product dumped in exposed red mud ponds which are radioactive, highly alkaline and environmental contaminant to soil, surface water and ground water and possess disposal threats. Recent trend in increased urbanization and modernization has plenty of use of exterior flooring by concrete pavers block depending upon traffic load and volume. Present work is to know whether this red mud can be reused as a sustainable construction material to replace cement. The XRF spectroscopic advantage is taken to determine the composition identities between red mud and OPC cement. The study reveals the optimized percentage of red mud blend with cement after neutralization normalization. It cannot be disposed of easily. Attempt has been made to use bajri as the coarse aggregate instead of 12mm chips. The crusher by-product is having less use as construction materials. So the spare of cement by compensating with red mud and use of bajri shall be cost effective, environmentally sustainable and convenient disposal of the harmful waste. The mechanical characteristics like compressive, flexural, and split tensile strength etc., at 0%, 10%, 20%, 30% and 40% replacement of cement by red mud is found by using compressive testing machine (CTM) and universal testing machine (UTM) adhering to IS : 15658 (2006) and amended in 2011. The 20% OPC cement substitution by red mud is found to be adequate and will maintain sustainability.

Nowadays plastics have become one of the main construction materials with a wide range of use in product design as well as construction industry of medium or large elements including buildings. Elements like pipes’ and cables insulation, storage tanks, skylights, roofing, windows and doors, insulation and temporary structures can be made entirely, partly or as a bonding compound in new material mixes like WPCs wood plastic composites, carbon or natural fiber reinforced plastic. Material of this study has a vast application in the field of tensile structures construction or tents in smaller scale. One of the most common uses of plastic in the building construction is insulation of large surfaces such are walls, roofs or floors that can come in different forms commonly in foam which amounts can be adjusted to fit any form, in a prefabricated form like SIP panels as well as to securely insulate smaller details like pipes or cables. It is frequently used in the timing of the exterior building planes too. A rife problem is allergies from raw organic material objects and building components like down, sisal, cotton, coir, sea grass, etc. that can cause serious sequels like asthma, eyes and other mucous maladies can be completely eliminated with synthetic plastic-based materials-nylon, polyester, and polypropylene. This paper intends to stream how different plastic-based materials can help attain sustainable position in modern contemporary architecture.
