N'ime afọ ole na ole gara aga, ụlọ ọrụ ihe owuwu ahụ enwewo ọganihu na mmepe dị egwu. Nke a emeela ka mmepe nke admixtures na ihe mgbakwunye nke oge a. Mgbakwunye na admixtures maka konkịtị bụ kemịkalụ bekee agbakwunyere na konkịtị ka mma ya anụ ahụ na kemịkal Njirimara. Ihe ndị a na-anọchi anya ngwaahịa dị iche iche nwere kemịkal dị iche iche.
Isi ihe dị iche n'etiti admixtures na ihe mgbakwunye bụ ọkwa nke a na-etinye ihe ndị ahụ na kọmpụta ma ọ bụ ciment. A na-agbakwunye ihe mgbakwunye na usoro mmepụta ciment, ebe a na-eme ihe mgbakwunye mgbe a na-eme ihe ngwakọta.
Gịnị bụ ihe mgbakwunye?
A na-agbakwunye ihe mgbakwunye na ciment n'oge nrụpụta iji meziwanye ihe onwunwe ya. Dịka ọmụmaatụ, ihe ndị a na-etinye na ciment na-agụnye alumina, lime, iron oxide, na silica. Mgbe agwakọta, ihe na-ewe iwe dị ka 1500 ℃ na-ekwe ka ciment nweta ikpeazụ chemical Njirimara.
Kedu ihe bụ Admixtures?
Admixtures maka ihe nwere ike ịbụ nke abụọ ụdị, organic na inorganic ogige. Multifunctional admixtures bụ ndị na-agbanwe ihe karịrị otu anụ ahụ ma ọ bụ chemical Njirimara nke ihe ngwakọta. Enwere ụdị admixtures dị iche iche maka ịmegharị akụkụ dị iche iche nke kọnkịtị. Enwere ike kewaa ngwakọta n'ime:
Ngwakọta Mbelata Mmiri
Ndị a bụ ogige ndị na-arụ ọrụ dị ka ndị na-emepụta ihe, nke na-ebelata mmiri nke ngwakọta ihe dị ka 5% na-agbanweghị agbanwe agbanwe. Mgbakwunye mmiri na-ebelata mmiri bụ ihe nrụpụta polycyclic ma ọ bụ phosphates. Mgbe agbakwunyere, admixtures ndị a na-abawanye ike mkpakọ nke ngwakọta ihe site n'ime ka ọ dịkwuo plastik. Ụdị admixture a na-ejikarị eme ihe na ala na okporo ụzọ.
Ndị na-ebelata mmiri dị elu
Ndị a bụ superplasticizers, nke na-abụkarị ihe mgbakwunye polymer nke na-ebelata ọdịnaya mmiri site na 40%. Site na admixtures ndị a, porosity nke ngwakọta na-ebelata, ya mere na-eme ka ike ya dịkwuo elu. Ndị a admixtures na-emekarị tinye n'ọrụ maka onwe compacting na sprayed ihe.
Ngwakọta ngwa ngwa
Concrete na-ewekarị oge iji gbanwee site na rọba gaa n'ọnọdụ siri ike. A na-ejikarị polyethylene glycols, chlorides, nitrates na fluorides metal eme ụdị ihe mgbakwunye ndị a. Enwere ike ịgbakwunye ihe ndị a na ngwakọta kọmpụta iji belata oge ọ na-ewe ijikọ na ịtọ.
Ngwa mgbakwunye ikuku
A na-eji admixtures ndị a eme ihe ngwakọta nke ikuku na-agbanye. Ha na-eme ka ntinye nke ikuku ikuku banye n'ime ngwakọta kọmpụta, yabụ na-emeziwanye ihe ndị dị ka ịdịte aka na ike site n'ịgbanwe nhịahụ nke ciment.
Ngwakọta azụ azụ azụ
N'adịghị ka accelerating admixtures na-ebelata bonding na ntọala, retarding admixtures na-abawanye oge ihe na-ewe ịtọ. Ngwakọta ndị dị otú ahụ adịghị agbanwe oke mmiri-ciment kama na-eji ígwè oxides na sugars gbochie usoro njikọ ahụ.
Ihe mgbakwunye ihe na ihe mgbakwunye bụ ụdị kemịkalụ ihe owuwu kacha mma ugbu a. Na Jufu Chemtech, anyị na ụlọ ọrụ admixture mpaghara na nke mba dị iche iche na-arụkọ ọrụ iji hụ na ndị ahịa anyị nwetara ngwaahịa kacha mma maka ọrụ owuwu ha.
