Ndị na-ahụ maka ike mmalite nwere ike belata oge nhazi nke ihe, mana mgbe ọdịnaya tricalcium aluminate dị na ciment dị ala ma ọ bụ dị ala karịa gypsum, sulfate ga-egbu oge nhazi oge ciment. N'ozuzu, ikuku nke dị na kọnkịta agaghị abawanye site na ntinye ike nke mbụ, na ikuku nke ikuku nke na-ebelata mmiri na-eme ka a na-ekpebi ihe ikuku nke na-ebelata mmiri. Dịka ọmụmaatụ, ọdịnaya gas agaghị abawanye mgbe ejiri mmiri na-ebelata mmiri nke calcium, mana ọ ga-abawanye nke ukwuu mgbe ejiri mmiri na-ebelata osisi calcium.

Onye na-ahụ maka ike mmalite nwere ike melite ike mmalite ya; Ọkwa nkwalite nke otu onye na-ahụ maka ike mmalite na-adabere na ọnụọgụ nke onye ọrụ ike mmalite, ọnọdụ okpomọkụ, ọnọdụ ọgwụgwọ, oke ciment mmiri na ụdị ciment. Mmetụta na ike ogologo oge nke ihe na-ekwekọghị ekwekọ, na elu na ala. Onye na-ahụ maka ike mmalite nwere mmetụta dị mma na usoro ọgwụgwọ ezi uche dị na ya, ma mgbe usoro ọgwụgwọ ahụ dị ukwuu, ọ ga-enwe mmetụta na-adịghị mma na ike ikpeazụ na ịdịte aka nke ihe. Ihe na-eme ka mmiri na-ebelata mmalite nke ike na-enwekwa mmetụta dị mma n'oge mbụ, na arụmọrụ ya dị mma karịa nke onye ọrụ ike mbụ, nke nwere ike ịchịkwa mgbanwe nke ike oge. Triethanolamine nwere ike kpalite ike simenti mbụ. Ọ nwere ike mee ngwangwa hydration nke tricalcium aluminate, ma na-egbu oge hydration nke tricalcium silicate na dicalcium silicate. Ọ bụrụ na ọdịnaya dị oke elu, ike nke ihe ga-ebelata.

Sulfate n'oge ike na-adịgide adịgide enweghị mmetụta na corrosion mkwado, ebe onye na-ahụ maka ike mmalite chloride nwere nnukwu ion chloride, nke ga-akwalite corrosion nkwado. Mgbe usoro onunu ogwu buru ibu, kemịkalụ nguzogide corrosion, iyi nguzogide na ntu oyi ga-ebelatakwa. N'ihi na ihe, ibelata flexural ike nke ihe na ịba ụba n'oge shrinkage nke ihe nwere obere mmetụta na mgbe e mesịrị ogbo nke ihe. Ugbu a, amachibidoro iji ihe mgbakwunye nwere chloride n'ụkpụrụ mba ọhụrụ. Iji gbochie mmetụta nnu chloride na nrụrụ nkwado, a na-ejikarị ihe mgbochi nchara na nnu chloride ọnụ.

Mgbe ị na-eji sulfate n'oge ike gị n'ụlọnga, ọ ga-amụba alkalinity nke ihe mmiri mmiri na-adọ, n'ihi ya, e kwesịrị ịrịba ama na mgbe nchịkọta nwere arụ ọrụ silica, ọ ga-akwalite mmeghachi omume n'etiti alkali na mkpokọta, na-eme ka ihe na-emebi n'ihi alkali. mgbasawanye.
