Several efforts are being made by researchers to turn concrete into a more sustainable material. Various research are being carried out to substitute cement in concrete, either whole or in part. The current work uses mineral admixtures like metakaolin and GGBS (blended concrete) to partially substitute cement in concrete. Concrete prone to cracking due to structural and Non-structural conditions. All kinds of fissures have the potential to harm concrete by letting water and other substances pass through them, which weakens and distorts the material while also compromising the reinforcing. To repair the concrete cracks, a certain type of treatment and routine upkeep are required, and they will be very costly. So, the current research is to study the impact of Bacteria (microbes) on crack healing as well as on properties of blended concrete. Different mixes of M25-grade concrete were done by using M-sand as fine aggregate to obtain the optimum percentage of GGBS used as supplementary cementitious material (0, 5%, 10%, 15%, 20%, 25%, and 30%), and the same percentage was used in blended concrete, which included metakaolin at different percentages (0, 5%, 10%, 15%, 20%, and 25%).Among different mixes, the proportions of blended concrete with enhanced mechanical properties were considered, and bacteria were induced at a constant percentage in that mix. The results indicated that the microbial blended concrete mix has significantly improved mechanical and durability properties, when compared to conventional and blended concrete mixes.

“…In addition, wollastonite powder has a high aspect ratio, meaning it has a large surface area compared to its volume. As a result, it serves as a helpful filler material that can aid in lessening the amount of cement needed in concrete production, thereby cutting costs and mitigating the environmental impact [29,30]. Another benefit of adding wollastonite powder to concrete is that it can improve its workability.…”

The production of cement results in a significant amount of energy consumption and CO2 emissions, which are major contributors to environmental pollution. Researchers have developed a ternary blended mix concrete to address these concerns by partially substituting cement with a combination of lime sludge (LS) and wollastonite powder (WP). This study investigated the mechanical properties (compressive strength, spilt tensile strength, and flexural strength) of a ternary blended concrete mix with a grade of M30. 180 specimens, including 60 cubes, 60 cylinders, and 60 prisms, were prepared for testing. The blended concrete mix was produced using different percentages of cement replacement by LS (5%, 10%, 15%) and WP (10%, 15%, 20%). The compressive strength for the ternary mix at 10% LS and 15% WP was 44.78 % higher than the conventional mix, the flexural strength ternary mix at 10% LS and 15% WP was 25.46 % higher than the conventional mix, and spilt tensile strength ternary mix at 10% LS, and 15% WP was 27.30 % higher than the conventional mix at 28 days and trend is almost same for 7,56 and 90 days . The results showed that a ternary mix containing 75% cement, 10% LS, and 15% WP exhibited the best mechanical properties.
