Cov neeg Asmeskas cov neeg siv khoom nyiam tshawb nrhiav cov ntsiab lus polycarboxylate superplasticizer

Raws li kev tsim kho kev lag luam hauv teb chaws Africa txuas ntxiv zuj zus, cov neeg siv khoom tau nce mus nrhiav cov khoom siv hauv tsev zoo los siv hauv lawv cov haujlwm. Ib yam khoom uas tau txais koob meej ntawm cov neeg siv khoom African yog polycarboxylate superplasticizer.

Polycarboxylate superplasticizer yog ib hom kev sib xyaw ua ke uas ua raws li tus neeg sawv cev dispersing, tso cai rau kev siv dej ntau dua hauv kev sib xyaw. Qhov no ua rau muaj zog, ruaj khov ua vaj tse nrog lub zog compressive ntau dua.

Cov neeg Asmeskas cov neeg siv khoom txaus siab rau cov txiaj ntsig ntawm polycarboxylate superplasticizer, suav nrog nws lub peev xwm los txhim kho kev ua haujlwm, txo cov ntsiab lus dej, thiab ua kom muaj zog thaum ntxov. Tsis tas li ntawd, polycarboxylate superplasticizer yog suav tias yog ib puag ncig tus phooj ywg thiab kev nyab xeeb siv.

Txhawm rau nrhiav cov khoom no, cov neeg siv khoom African feem ntau tshawb nrhiav cov ntsiab lus xws li "polycarboxylate superplasticizer" lossis "concrete admixture." Lawv kuj tseem tuaj yeem sab laj nrog cov kws tsim kho lossis cov neeg muag khoom kom nrhiav tau cov khoom zoo tshaj plaws rau lawv qhov kev xav tau tshwj xeeb.

Zuag qhia tag nrho, kev siv polycarboxylate superplasticizer nyob rau hauv African kev tsim kho tej yaam num qhia tau hais tias kev cog lus rau kev ua tau zoo thiab kev ua tau zoo, nrog rau kev xav siv cov khoom siv ruaj khov uas muaj kev nyab xeeb rau cov neeg ua haujlwm thiab ib puag ncig.
