1.Mmepe nke ihe osooso nke calcium nnu

Calcium salts nwere ike ibelata uru PH nke usoro C3S-H2O, si otú accelerating hydration nke C3S, nke n'aka nke ya na-eme ka hydration na ike siri ike nke ciment dị ngwa ngwa. Calcium salts nwere mmetụta a na enweghị ion chloride., sodium na potassium ion gụnyere calcium nitrate, calcium formate na calcium bromide.Calcium formate bụ ihe kasị mma dochie calcium chloride.Calcium nitrate nwekwara ezi mmalite ike mmetụta na Portland ciment., mana mmetụta simenti Portland agwakọta ya na ihe agwakọtara adịghị ike, ma ekwere m na nke ahụ site na omimi nke nyocha, Calcium nnu ga-abụ otu n'ime ihe ọhụrụ ihe osooso ka mma mmepe iche.

2.Ọmụmụ ihe ọzọ na mmetụta nke ọgbọ ọhụrụ nke ogige organic na inorganic na ihe osooso
