Cement Replacement Material - an overview

Considering the example of a cement replacement material, few new products for use in concrete will be suitable for the full range of uses of Portland cement. Many may only be suitable for low strength concrete, or possibly masonry blocks. This will reduce their economic value, but will probably still be worth pursuing because low-strength products have numerous

Replacing Portland cement CEM I with GGBS reduces the temperature rise and helps to avoid early-age thermal cracking. The higher the percentage of GGBS, the lower the rate of reaction and consequently the slower the rate at which heat is developed. This will result in reduced peak temperatures and reduced thermal strain. Strength gain in GGBS concrete. With the same
