(in lingua inglese)
Inclusion of local by-product slag that is cooled by water (WCS), in OPC matrix has a positive effect on the microstructure of concrete, where a partial replacement of OPC with 50% WCS in OPC paste mixes resulted in an increase in the amount of calcium silicate hydrate (CSH) by 57%, a decrease in the amount of calcium hydroxide (CH) by 66%, and a decrease in the amount of capillary pores by 57%, compared to those in the pure OPC matrix.
