A review on recent advances in the fabrication and evaluation of
The ability of concrete matrix to resist water penetration is affected by the porosity and pore structure, which largely depend on the water-cement ratio, total cement content, supplementary cementitious materials and other factors involved in the concrete mix design, curing process, and construction methods [160, [169], [170], [171]]. Hence ...
Fillers in cementitious materials — Experience, recent advances …
The use of limestone as a replacement for clinker was most likely introduced into cement standards as an answer to the oil crisis [14] during the 1970s. Canada adopted a 5% limestone limit in normal Portland cement by 1983 (CAN3-A5-M83), and by 1988, the Europeans were already drafting proposals to allow 20% of filler in Portland-composite or …
