Ndị na-emepụta Calcium Aojin Chemical na-ekerịta ngwa ya na ụlọ ọrụ ciment na-ewu. Aojin Chemical na-ere calcium formate nwere nnukwu 98% ọdịnaya, ngwugwu na 25kg akpa.
A na-eji Calcium formate (Ca (HCOO)₂), onye na-emepụta ihe na-emepụta ihe na-emepụta ihe na ciment n'ihi njirimara kemịkal pụrụ iche. Ọrụ na ngwa ya bụ isi bụ ndị a:
1. Ike mmalite na nhazi ngwa ngwa
Calcium formate na-eme ngwa ngwa hydration ciment, ọkachasị hydration nke tricalcium silicate (C₃S) na tricalcium aluminate (C₃A). Nke a na-eme ka nhazi na nhazi nke ngwaahịa hydration ngwa ngwa (dị ka ettringite na calcium hydroxide), si otú ahụ na-eme ka ike mmalite nke ihe ndị dabeere na ciment (ike nwere ike ịbawanye site na 20%-50% n'ime ụbọchị 1-7). Ngwongwo a na-eme ka ọ dị mma maka ihe owuwu dị ala (dị ka ịwụsa oyi) ma ọ bụ ọrụ nrụzi ihe mberede, na-ebelata oge ọgwụgwọ yana hụ na ihe siri ike na-esikarị ike na gburugburu ebe okpomọkụ dị ala, si otú a na-egbochi mmebi oyi.
2. Mmelite arụ ọrụ Concrete na ịdịte aka
Na tapawa ciment, calcium formate na-ebelata ọbara ọgbụgba na nkewa, na-eme ka ihe jikọrọ ọnụ na njupụta. Ọzọkwa, ngwaahịa hydration ya na-ejupụta pores nke tapawa ciment, na-ebelata porosity, na-eme ka enweghị ike ime ihe, nguzogide ntu oyi, na nguzogide corrosion, si otú ahụ na-agbatị ndụ ọrụ ciment.
3. Kwesịrị ekwesị maka ngwa ngwaahịa ciment dị iche iche
Na mmepụta akụrụngwa precast, dị ka paịlị precast na ọkpọkọ ọkpọkọ, usoro calcium na-eme ka ntụgharị ebu dị ngwa ngwa, na-ebelata oge nbibi, ma na-emezi nrụpụta nrụpụta.

Ngwa ngwa ngwa na ihe eji eme ihe: Ọ na-eme ka njide mmiri na ike mmalite nke ngwa agha dịkwuo mma, na-eme ka ọganihu ngwa ngwa n'ime masonry na plasta.
4. Uru gburugburu na ndakọrịta
Ọnụ ego usoro calciumabụghị ihe na-egbu egbu na nke na-adịghị ewe iwe, yana dakọtara na ciment, ihe ndị na-ebelata mmiri, uyi ọkụ na ihe ndị ọzọ.
