The effect of blast furnace slag chemistry on carbonation characteristics of cement-slag systems

In order to compensate the limited availability of raw material resources and meet the growing demand for decreasing CO2 emissions during cement and concrete productions, a practical method is to decrease the clinker content in cement. This strategy mainly consists of substituting a part of the clinker with supplementary cementitious materials ...

The effect of slag chemistry on CO₂ binding capacity of C₃S-slag (-gypsum) system

In this paper, the authors investigated the correlation between slag chemistry and CO₂ binding capacity of the blended system. To simplify the composition of mixture, model paste containing C₃S, slag covering the common composition range and gypsum was employed. After accelerated carbonation test, three CO₂...
