Innovative Sustainable Solution for High-Strength Quaternary Cement Concrete with Lime Powder

An experimental study was conducted to regulate the impact of the mechanical behaviour of quaternary concrete made with additional cementitious ingredients. In predetermined ratios, fly ash (FA), lime powder (LP), and silica fume (SF) were combined by swapping out 30–50 per cent of the weight of regular Portland cement (OPC). For all mixtures, water-to-binder ratio and the total amount of cementitious ingredients were held constant at 0.35 and 402 kg/m3, respectively. At 7, 28, 56, 90, 180, and 365 days, tests were conducted to evaluate the mechanical behaviour of quaternary concretes, and the results were compared to those obtained for controlled concrete (100% OPC). According to the normal code of practise in India, the complete exercise was prepared, cured, and tested. In addition, durability properties were investigated in terms of permeability and chemical attack. In some permutations of mixes, it was discovered that the strength of the concrete with quaternary binders was greater than that of the controlled concrete because of the cement’s synergistic activity with the addition of additional cementitious materials. According to the test results, optimal mixes of FA, SF, and LP as a partial replacement for OPC as quaternary concrete would be a better choice than 100% controlled concrete.
