Performance of High-Strength Concrete using Alccofine and GGBFS

Performance of High-Strength Concrete using Alccofine and GGBFS India currently being the second-largest producer of steel in the world and is blooming, meeting the market demand of the robustly growing infrastructure industry, and subsequently producing a massive amount of slag influx as a by-product. This slag is used to produce ground granulated blast furnace slag (GGBFS). GGBFS has already established itself as a good cementitious material in the concrete world. High-strength concrete (HSC) is extensively used in various civil engineering constructions. The necessary ingredients recommended in IS 10262–2019 code are mineral admixtures such as micro-silica and (GGBFS) as replacements to cement to produce cost-effective and environmentally friendly concretes. In addition, the high range water reducer (HRWR) plays a vital role in producing high workable HSC with low to very low water-cement (w/c) ratios. In this work, an attempt has been made to study the mix design for standard concretes ranging from M30 to M60 and HSCs from M65 to M100 based on the provisions of new code IS 10262-2019.

Abstract

India currently being the second-largest producer of steel in the world and is blooming, meeting the market demand of the robustly growing infrastructure industry, and subsequently producing a massive amount of slag influx as a by-product. This slag is used to produce ground granulated blast furnace slag (GGBFS). GGBFS has already established itself as a good cementitious material in the concrete world. High-strength concrete (HSC) is extensively used in various civil engineering constructions. The necessary ingredients recommended in IS 10262–2019 code are mineral admixtures such as micro-silica and (GGBFS) as replacements to cement to produce cost-effective and environmentally friendly concretes. In addition, the high range water reducer (HRWR) plays a vital role in producing high workable HSC with low to very low water-cement (w/c) ratios. In this work, an attempt has been made to study the mix design for standard concretes ranging from M30 to M60 and HSCs from M65 to M100 based on the provisions of new code IS 10262-2019. Excel platform is used for the mix design covering a range of parameters. Three typical grades namely M30, M80, and M100 concrete are considered for the laboratory studies, keeping in mind the importance of trial mixes. The various tests conducted on these concretes are compressive strength, split tensile strength, flexural strength, water absorption, rapid chloride permeability test (RCPT), and microanalysis by conducting scanning electron microscope (SEM), energy-dispersive spectroscopy (EDS), and X-ray diffraction (XRD) tests. The new mix design code is a boon to civil engineers for producing HSC. Few important conclusions are drawn based on the experimental results.
