Effect of Al₂O₃ content in slag on the relationship between slag reactivity and carbonation resistance

To understand the influence of slag chemistry on the carbonation resistance of slag-rich cement, this paper explored the carbonation characteristics of blended cement systems with different Al₂O₃ contents in slag through accelerated carbonation test. Irrespective of slag chemistry, three main CO₂ binding...

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 ...
