High ggbs concrete
WebThis may increase the strength of concrete against cracking. GGBS is used as a direct replacement for Portland cement, on a one-to-one basis by weight. Replacement levels for GGBS vary from 30% to 85%. Typically, 40 to 50% is … WebIt was inferred from their results that SCC mixes with high volume GGBS reduced strength, and concrete with low volume yielded high-strength limiting cement replacement level. Kiran et al. (2014) have done a study on SCC using RHA and GGBS as partial cement replacement for M30, M40, and M60 grades.
