Mmetụta Superplasticizer na Concrete Ọhụrụ

mmetụta nke superplasticizer na ihe ọhụrụ

Mmetụta nke superplasticizer na njirimara nke ihe ọhụrụ na-adabere na ụdị na usoro onunu ogwu. A na-eji superplasticizer eme ihe iji kwalite oke mmiri-ciment, workability na ike nke ihe. Ọ nwekwara ike imeziwanye nrịba nke konkịtị ma welie njirimara nhazi onwe ya site na ibelata ọdịnaya mmiri.

Na mmalite nkebi nke hydration, superplasticizer na-akwalite mmeghachi omume hydration siri ike site na imebi njikọ dị n'etiti akụkụ ciment nke na-ebute oke mmiri na permeability.. Ọ na-ebelatakwa w/b ration nke ciment na-eme ka ike mmalite dịkwuo elu na ịdịte aka ka mma.

Enwere ike iji ya dị ka admixture bụ isi na ngwakọta nke kọmpat na-emekọ onwe ya maka ịdịte aka ka mma, ma ọ bụ dị ka nke abụọ admixture na ndị ọzọ na-ebelata mmiri ihe mgbakwunye na ike dị elu na ihe siri ike na ihe siri ike iji belata ojiji nke ndị na-ejigide mmiri na-agwọ ọrịa..

Enwere ike ịgwakọta admixture a na ihe ndị akọrọ, ma ọ bụ tinye ya na mmiri 10-15 nkeji tupu eme nkedo. Enwere ike ịgbakwunye ya na ihe n'oge ị na-agwakọta na igwe igwe ma ọ bụ ngwa ngwa igwekota (oge agwakọta bụ 3 nkeji).
