In the world full of crises, also the rising demand for PPE suits and masks would lead to another wave of biomedical waste disposition crises. The disposal of thrown away wastes causes a serious issue as the waste are most of the time are non- biodegradable and these are also not fit for incineration. Soil stabilization improves the engineering properties of the weak soil, by proper compaction and additional materials such as lime, concrete, but these materials are becoming expensive day by day, hence plastic by the composition of egg shell powder could enhance the properties and can be a sustainable replacement for lime, concrete, etc. as stabilizer. Through much experimental investigation it has been showed that plastic and egg shell powder can be used as an effective stabilizer with encountering waste disposal problem as well, along with the economical solution for stabilizing weak soil. This PPE stripes/shredding are known for its high strength, low cost, significantly less dangerous for the environment. The combined effect of PPE stripes/shredding along with egg shell powder can enhance engineering properties of soil.

Soil stabilization is a mechanical or chemical alteration of one or more soil properties to create an improved soil material possessing the desired engineering properties. The aim of this article was to review bioenzyme-based soil stabilization techniques with an emphasis on bioenzymes production, mechanism of soil stabilization and future challenges, and opportunities of the sector. Soils are stabilized to increase strength and durability or to prevent erosion and dust generation. Cost-effective soil stabilization technology has been a fundamental part of any construction and is very important for economic growth in any country. In some cases, construction has been challenged due to the high cost of soil stabilization processes. Besides, methods of stabilizations using common stabilizing agents are getting costly. Currently, there is a growing interest to identify new and green technology to improve construction techniques and to expand the road network. Therefore, the search for new materials and improved techniques to process the local materials has received an increased focus. For developing countries, bioenzymes are now creating an opportunity to improve soil stability with tremendous effectiveness in the overall process of soil stabilization. In the world, bioenzymes have been used in different projects for several years and are generally proprietary products, often of patented formulation that needs intensive field tests. Currently, the use and production of bioenzymes is becoming the most promising key for the advancement of a country by saving time, energy, and finance. It also reduces environmental pollution due to carbon emission by the conventional stabilizers. Thus, a better understanding of this emerging technology is of utmost importance to exploit any improvement it can offer to soil stability. With little research and practice, it is possible to produce soil stabilizing bioenzymes using local raw materials. Due to this, production of low cost, easily and widely applicable, and environmentally friendly enzymatic formulations from locally available raw materials should be the interest of research and academic institutes of any country.

Polymer concrete has high durability, high abrasion resistance, and high strength, compared to ordinary Portland cement concrete. However, because of high cost of binder, it has not been used in construction field generally. The properties of unsaturated polyester polymer concrete used the steel slag fine aggregate of spherical type as an aggregate for polymer concrete in fresh and hardened state were studied. This research shows that the unsaturated polyester polymer concrete have high workability, high strength and low cost due to decreasing the polymer content, when steel slag fine aggregate of spherical type was used.


One of the factors that affect the long term performance of a structure is the strength of the underlying soil strata. Presence of weak soil strata beneath the structure will affect the structural integrity. So, enhancing the engineering properties of the weak soil results in the betterment of bearing capacity of the soil. Nowadays, for improving the stability of the weak soil, various soil stabilization techniques are adopted. This paper presents an investigation of using alccofine as a soil stabilizing agent. Variation in shear strength parameters and compaction parameters of the soil is studied by adding different percentages of alccofine 1101 such as 1%, 2%, 3%, 4%, and 5%. Test results revealed that at the optimal rate of alccofine 1101, the shear strength characteristic is increased by 53.71% after a curing period of 3 days.


In present scenario concrete is highly consumed material in construction field due to its advantages, because of this the natural resources are depleting day by day at an alarming rate and there is an immediate need for finding alternate materials to the natural materials in concrete. In this paper an effort is made to find alternate partial replacement materials for cement and fine aggregate (FA). M40 grade concrete is adopted and the cement was replaced with egg shell powder with different percentages of 5%, 10% and 15%. The optimum percentage egg shell powder (ESP) is obtained at 10%. At optimum ESP the FA is replaced with Quarry Dust (QD) with percentages of 25%, 50%and75%. The maximum strength properties are obtained at 10% ESP and 50% QD and the concrete is also durable at 10% ESP and 50% QD with Water Cement Ratio is 0.38.

This study presents the effects of egg shell powder on lightweight foamed concrete when partially replace the cement. At 2017, 12235 million eggs were consumed and around 85 thousand tonnes of egg shell waste was the yield in Malaysia. The waste might result in an environmental problem if it is not reused properly. Besides, large cement production also results in carbon dioxide emission and depletion of natural limestone. Therefore, studies on effects of egg shell powder on properties of lightweight foamed concrete as partial replacement of cement is attractive to be carried out by aiming to promote the application of lightweight foamed concrete as well as to mitigate the environmental issue by reducing the number of eggshell wastes and pure cement production. The objective of this study is to investigate the effects on engineering properties of lightweight foamed concrete with a fresh density of 1200 ± 50 kg/m3 when the cement is partially replaced by egg shell powder at replacement levels of 0%, 2.5%, 5%, 7.5%, and 10% by mass. The properties of the lightweight foamed concrete studied included workability, stability, compressive strength, flexural strength, water absorption, and sorptivity. The results show that the replacement of egg shell powder reduces the spread diameter, stability, and sorptivity, and improve the compressive and flexural strengths at replacement level of up to 5%. The eggshell powder is feasible to be used as partial cement replacement material for the production of the masonry unit.

Abstract Purpose Stabilization of weak soil can be achieved through different methods, some of which include jet column, cement stabilization and fly ash stabilization. Unfortunately, the use of the aforementioned methods of soil improvement affects the environment negatively thereby leading to environmental degradation. With the aforesaid impediment in mind, the need for devising methods of weak soil improvement becomes pertinent. Methods Bacillus sp. — a non-pathogenic organism found abundantly in soil — was investigated in this study as a potential agent of soil improvement. The usability of Bacillus sp. in soil improvement was investigated with direct shear tests and permeability tests under optimum conditions in this study. Result Time-dependent study on the effect of the ureolytic bacteria Bacillus sp.-induced calcium carbonate precipitation shows reduction in permeability and increase in the strength of the soil under study. On exhaustion of the available nutrients in the soil, however, the strength of the soil is not negatively impacted. Conclusion Microbially induced calcium precipitation by Bacillus sp. is effective in soil improvement as such it may serve as substitute for conventional soil stabilization techniques. The ability of the bacteria to precipitate calcium carbonate in the soil leads to reduction in the permeability and increase in the shear strength of the soil.

— Soil stabilization is a process by which the strength, stiffness and bearing capacity of road foundations are improved by either mechanical or chemical means. Structures need a stable foundation for their proper construction and lifelong durability. Foundation needs to rest on soil ultimately, transferring whole load to the soil. If weak soil base is used for construction, with passage of time it compacts and consolidates, which results in differential settlement of structure. It may result in cracks in structure which can have catastrophic affect too. To avoid these future problems in weak soil, stabilized soil should be considered. The soil sample is collected from “Alandurai”. The soil properties are identified by conducting different laboratory tests such as Sieve grain analysis, Atterberg limits, Specific gravity using Pycnometer, Standard Proctor tests, California Bearing ratio test. From the tests results soil is classified as Fine grained red soil. The most commonly found soil around the sample soil collected. The stability of the soil is found using C.B.R test. Natural soil is both a complex and variable material. Yet because of its universal availability and its low cost winning it offers great opportunities for skilful use as an engineering material. However the soil at any particular locality is unsuited, wholly or partially, to the requirements of the construction engineer. A basic decision must therefore be made whether to accept the site material as it is and design to standards sufficient to meet the restrictions imposed by its existing quality. Remove the site material and replace with a superior material. Alter the properties of existing soil so as to create a new site material capable of better meeting the requirements of the task in hand. Lime and Geogrid were selected for the stabilisation of soil.1 to 6 percent of Lime are added and its optimal value is identified. Apparently CBR tests are done after introducing Geogrid and stability of the soil is identified. Analysis the performance of thickness of pavement in conventional soil, Lime stabilised soil and geogrid reinforced soil. Cost Estimation of the pavement is done and difference in the cost is identified.

The application of chemical stabilizer in soil stabilization can effectively reduce the negative environmental impact in the construction industry. However, the stabilization of soft clay remains a challenge due to the costly and non-eco-friendly materials such as cement and lime. This research demonstrates the combination of SF and ESA in stabilizing the kaolin soils, based on the basic engineering properties and undrained shear strength (USS). Its effect was studied via the inclusion as cement replacement material in kaolin soil at 2, 4 and 6% (by weight of dry soft kaolin clay soil) of SF and ESA substitutions of 3, 6 and 9% (by weight of dry soft kaolin clay and SF content). The result shows a considerably lower specific gravity (4.9% reduction), reduced plasticity index (PI)(48.4% reduction), decreased maximum dry density (MDD) (5.5% reduction), increased optimum moisture content (OMC)(8.7% increment), and higher USS (68.8%). In conclusion, the combinations of SF and ESA as soil stabilization agents successfully enhance the soil strength of the kaolin opening a route to the low cost and eco-friendly materials in soil stabilization.
