Portland Cement Properties - A Civil Engineer

Updated June 18th, 2020We generally use hydraulic cement in our construction which is best known as Portland cement. Cement properties vary in different "types of cement" because of different percentage of "cement ingredients". To construct economical concrete structures or cementitious product it is essential to know the properties of cement. Cement properties can be categorized [.]
