“…[40][41] Increment in strength was also noted by various researchers. [42][43][44] Chouhan et al 45 evaluated the performance of substituting sand with Kota stone slurry by conducting various tests. It was concluded that sand could be substituted by Kota stone slurry up to 40% of replacement.…”

Concrete is highly used construction material with cement being its major ingredient. Also, the demand for good quality of concrete is increasing because of the fast-growing urbanization. But there are certain problems associated with the manufacturing of cement. One of the major problems being production of carbon dioxide causing pollution in environment, the manufacturing of cement is quite expensive and it also leads to the depletion of resources. In order to curtail the consumption of cement, it has become inevitable to replace cement by certain amount with substituent materials that are cheaper to produce in order to lower down the financial cost of concrete production by some extent. The review paper, elaborates many properties of concrete by the inclusion of Kota stone slurry after evaluating several research papers. The following paper discusses numerous properties of concrete including workability, compressive strength, split tensile strength, water absorption and modulus of elasticity. The paper demonstrates that when used appropriately, inclusion of Kota stone slurry in concrete had a positive impact on concrete by increasing the strength and durability.

This study aims to evaluate the chloride diffusion coefficient and the service life (SL) of concretes containing metakaolin and high-slag blast-furnace cement (HSBFC). Accelerated methods of chloride ion diffusion and migration (RCPT, RMT, BDT and multiregime test method) were used. To produce the specimens, HSBFC resistant to sulphates (CPIII 40 RS) was partially replaced by metakaolin in the contents of 4%, 8% and 12%. Statistical analysis was performed by means of Analysis of Variance (ANOVA) and Tukey's Test to the chlorides diffusion coefficients obtained from different test methods. Similarity between diffusion by immersion (BDT) and non-stationary migration test (RMT and multiregime method) results was noted, however, with differences regarding to the stationary regime. The average diffusion coefficient obtained in the concrete specimens with 8 and 12% metakaolin as HSBFC partial replacement was 40-45 % lower than the reference mixture, providing an SL increase of approximately 70%. The most efficient metakaolin content obtained for overall mechanical and durability properties of concrete was 8%. This study also showed that HSBFC partial replacement by metakaolin can be beneficial even at later ages, as in 150 days.

“…SCMs present the potential to compensate for the partial removal of cement or even enhance the properties of concrete by filling the pores of the material. If the proper dimensions and chemical properties are used, these materials can become pozzolanic materials, by combining themselves to calcium hydroxide and with the different types of cement [6][7][8][9].…”

Life Cycle Assessment of Waste Glass Powder Incorporation on Concrete: A Bridge Retrofit Study Case

et al. 2022

View full text Add to dashboard Cite

The construction sector is responsible for some of the highest energy and natural resources consumption. In this context, new materials and solutions are created aimed at developing sustainable alternatives. While the literature presents papers that evaluate the mechanical and durability properties of concrete with glass waste powder and account for its environmental impact, no papers have executed the evaluation considering the retrofit of bridges. Furthermore, no papers evaluating the materials, construction, and maintenance could be found. Hence, this study proposes a technical and sustainable solution for the retrofit of the Third Bridge of Vitoria, an important intercity urban connector. This study evaluates both the technical and the environmental performance of structural concrete elements, considering the partial substitution of cement with glass waste powder and a baseline scenario with conventional concrete. The environmental impacts were evaluated through the life cycle assessment tool. The results indicate that incorporating waste glass powder in the prestressed hollow-core slabs as a partial cement replacement can improve the durability-related properties and mitigate environmental impact. It also shows that the manufacturing phase is the most impactful and that glass powder can significantly reduce the impact of maintenance.
