A responsible approach towards sustainable development requires the use of environmentally friendly, low-carbon, and energy-intensive materials. One positive way is to use glass waste as a replacement for fine natural aggregate. For this purpose, the effects of adding glass cullet to the mechanical properties of mortar were carried out. The glass aggregate made from recycled post-consumer waste glass (food, medicine, and cosmetics packaging, including mostly bottles), were used. This experimental work included four different contents of fine glass cullet (5, 10, 15, and 20 wt.% of fine aggregate). The compressive, flexural, and split tensile strengths were evaluated. Moreover, the modulus of elasticity and Poisson coefficient were determined. The addition of glass sand aggregate increases the mechanical properties of mortar. When comparing the strength, the obtained improvement in split tensile strength was the least affected. The obtained effect for the increased analysed properties of the glass sand aggregate content has been rarely reported. Moreover, it was determined that by increasing the recycled glass sand aggregate content, the density of mortar decreased. In addition, the relationships between the properties for mortar containing glass sand aggregate were observed.

The proposed study present behaviour of concrete with inclusion of waste foundry sand (WFS), waste glass, and glass fiber in different concrete trial mixes. Waste foundry sand (WFS) is basically by-product formed from metal casting industries ferrous or non-ferrous, which due to rapid concrete construction in world used as an alternative of sand. Waste glass can be used in concrete in crushed form as a replacement of aggregate or in powdered form as a replacement of cement, the only problem with waste glass is it is prone to alkali-silica reaction due to different composition of different types of glasses. Glass fiber is added with waste glass and waste foundry sand (WFS) to increase strength. Normal concrete grade M25 (1:1:2) is used for this experimental purpose, different concrete trials were casted which consist of replacement of sand with waste foundry sand in different proportion (0%, 10%, 20%, and 30%). Next trial consists of optimum value of (WFS) with different proportion of waste glass (0%, 10%, and 20%, 30%) as a replacement of fine aggregate. Final trial consists of addition of glass fiber (0%, 0.25%, 0.50%, and 0.75%) in optimum value of second trial. Mechanical properties of concrete compressive strength, split-tensile strength, flexural strength was examined at 7, 14, 28, and 56 days curing period.

Abstract This study includes the effect of using different dosages of integral waterproof Admixture and silica fume on some mechanical properties of concrete. Concrete improved by using different ratios of integral water proof admixture(IWP admixture) to increase strength and durability, this admixture used as percentages from cement weight in each mix ranged from 0.0% to 2% ( 0.0, 1.0%, 1.2%,1.4%,1.6%,1.8%, and 2%), compressive strength test done for cubes with (10*10*10) cm for each mix. The flexural strength test was done by (10*10*40) cm beams and tested after 28 days of curing. comparison study was made between silica fume mixes properties and mixes without silica fume. Adding IWP admixture leads to increase mechanical properties of ordinary concrete, the reference mix shows compressive strength equal to 26.38 MPa, while mixes with 2% IWP gives 38.8 MPa in this study. The study also includes the effect of using 2 main dosages of silica fume to the mixes that contain IWP, the new concrete with two admixtures show better values of compressive, tensile and flexural strength comparing with mixes with only IWP, the compressive strength increased from 38.8 MPa for ordinary IWP mixes to 52.3 MPa for 10% silica fume concrete mixes, and also the flexural strength increased from 4.8 MPa for mixes with only IWP to 7.3 MPa for mixes modified with 10 % silica fume. Study include also using waste glass as fine aggregate in mixes contain IWP and 10% silica fume and that show more increment in mechanical properties also.

The World

The progressive increase in the amount of glass waste produced each year in the world made it necessary to start the search for new recycling methods. This work summarizes the experimental results of the study on mortar samples containing dispersed reinforcement in the form of glass fibers, fully made from melted glass waste (bottles). Mortar mixes were prepared according to a new, laboratory-calculated recipe containing glass fibers, granite as aggregate, polycarboxylate-based deflocculant and Portland cement (52.5 MPa). This experimental work involved three different contents (600, 1200, and 1800 g/m3) of recycled glass fibers. After 28 days, the mechanical properties such as compressive, flexural, and split tensile strength were characterized. Furthermore, the modulus of elasticity and Poisson coefficient were determined. The initial and final setting times, porosity, and pH of the blends were measured. Images of optical microscopy (OM) were taken. The addition of glass fibers improves the properties of mortar. The highest values of mechanical properties were obtained for concrete with the addition of 1800 g/m3 of glass fibers (31.5% increase in compressive strength, 29.9% increase in flexural strength, and 97.6% increase in split tensile strength compared to base sample).

The utilization of solid waste materials or industrial waste as partial substitution of cement is growing in construction industry all around world. Less cement consumption causes consequently reduction in CO2 emission into the atmosphere and reduction in energy consumption. This paper examines the possibility of using finely ground waste glass as a partial replacement for cement and as a sealing admixture. Glass powder used in the research was prepared from the glass waste obtained from a local recycling company. Glass cullet made of brown glass, which after rinsing to remove sugars and other impurities, was dried and ground to a fraction below 125 μm.This paper is the revised version of the paper that has been published in the Proceedings of the Creative Construction Conference 2018 (Horszczaruk and Brzozowski, 2018).

With an objective of saving the environment by providing crumb rubber as an alternative to natural fine aggregate this paper presents a study carried out to find the mechanical properties of rubberized concrete. Rubberized concrete is made up of waste rubber from vehicle tyres and other rubber waste which otherwise is left out polluting the environment. In this paper, 7.5% of crumb rubber (obtained by shredding the vehicle tyres) as an alternative to fine aggregate and 7.5% of fly-ash as an alternative to cement is added with other ingredients of concrete to produce an eco-friendly concrete which can be used economically and effectively for construction along the coastal areas. Various properties like workability, compressive strength, split tensile strength, and flexural strength was carried out on concrete specimens exposed to the natural marine environment along the coast of Visakhapatnam, Andhra Pradesh. The total exposure of concrete specimen was about 150 days, and various specimens were tested at 7, 28, 90, 120 and 150 days, respectively. The test results showed that with a slight compromise in strength, the workability of concrete and resistance to the effect of seawater on the strength of concrete significantly improved with the addition of crumb rubber and fly-ash.

AbstractIndustrial waste has been rapidly increased day by day because of the fast-growing population which results environmental pollutions. It has been recommended that the disposal of industrial waste would be greatly reduced if it could be incorporated in concrete production. In cement concrete technology, there are many possibilities to use waste materials either as cement replacement or aggregate in concrete production. Two major industrials waste are glass and marble waste. The basic objective of this investigation is to examine the characteristics of concrete waste glass (WG) as binding material in proportions 10%, 20% and 30% by weight of cement. Furthermore, to obtain high strength concrete, waste marble in proportion of 40%, 50% and 60% by weight cement as fine aggregate were used as a filler material to fill the voids between concrete ingredients. Fresh properties were evaluated through slump cone test while mechanical performance was evaluated through compressive strength and split tensile strength which were performed after 7 days, 28 days and 56 days curing. Results show that, workability of concrete decreased with incorporation of waste glass and marble waste. Furthermore, mechanical performance improved considerably up 20% and 50% substitution of waste glass and waste marble respectively. Statistical approach of Response Surface Methodology (RSM) was used optimize both waste materials in concrete. Results indicate better agreement between statistical and experimental results.

Study Results

Increasing human awareness of the importance of protecting the environment and conserving natural resources requires concrete innovation as an environmentally friendly and sustainable material. Accumulated of solid waste begins to be processed and reused, one of which is as a constituent of concrete. Among the various types of solid waste, glass waste is considered as an alternative that can be used as a substitute for fine aggregate (sand), coarse aggregate (split stone) and cement. This study investigated the use of mix coloured glass waste consisting of clear, green, and brown as partial substitution of sand in concrete. Although the glass colors were mixed, the proportion of each color had been determined in this study, namely 25%, 25%, and 50%. The purpose of determining these proportions is to find out which type of color glass has the most effect on concrete mix. The target characteristic strength of 25 MPa was produced by replacing sand with 20% of mix coloured waste glass. Three combinations of concrete mixes were prepared for this study. Compression tests were conducted at 7, 14, and 28 days. Workability of fresh concrete, density, compressive strength, and failure mode were investigated in this study. Results showed that the use of waste glass was able to increase the workability of fresh concrete. K1, K 2, and K3 obtained slump values which were 4%, 6,7%, and 1,3% higher than normal concrete. Normal concrete and all combinations exhibited similar density values. Only normal concrete achieved the characteristic strength of 25,7 MPa at 28 days. Meanwhile K1, K2, and K3 achieved strengths of 22,4 MPa, 22,1 MPa, and 24,7 MPa, respectively. It was evident that as workability values increased, the compressive strengths were noticed to reduce.
