Concrete admixtures yog dav siv nyob rau hauv lub tsev, yog li qhov zoo ntawm cov pob zeb admixtures tiag cuam tshuam rau qhov zoo ntawm qhov project. Cov chaw tsim khoom ntawm pob zeb dej txo tus neeg sawv cev qhia txog qhov tsis zoo ntawm cov pob zeb sib xyaw. Thaum muaj teeb meem, peb yuav hloov lawv.

Ua ntej, qhov teeb meem txawv txav tshwm sim thaum sib tov ntawm cov pob zeb tshiab, xws li kev teeb tsa sai, kev teeb tsa tsis tseeb thiab lwm yam tshwm sim, ua rau poob sai sai.

Qhov thib ob, los ntshav, cais thiab stratification ntawm pob zeb yog loj heev, thiab lub zog hardening yog pom tseeb txo.

Qhov thib peb, qhov poob ntawm cov pob zeb tshiab tsis tuaj yeem txhim kho, thiab zoo li cov dej txo cov nyhuv ntawm cov pob zeb ntxiv tsis zoo.

Plaub, lub pob zeb shrinkage nce, impermeability thiab durability txo, thiab cov nyhuv retarding nyob rau hauv loj cheeb tsam pob zeb yog tsis pom tseeb, thiab kub qhov sib txawv tawg tshwm.

Concrete admixtures tuaj yeem nqa tau yooj yim rau kev tsim kho, thiab tau siv dav hauv kev tsim kho kev lag luam. Peb twb tau qhia txog kev xaiv cov pob zeb sib xyaw ua ntej. Ntawm no dua peb hais txog kev xaiv ntawm additives.

1. Hom kev sib xyaw yuav tsum raug xaiv raws li kev tsim qauv engineering thiab kev tsim kho, thiab tom qab ntawd txiav txim siab raws li qhov kev xeem thiab cov kev sib piv ntawm kev lag luam thiab kev lag luam.

2. Nws yog txwv tsis pub siv cov khoom sib xyaw ua ke uas tsim kev puas tsuaj rau tib neeg lub cev thiab ua paug rau ib puag ncig.

3. Rau tag nrho cov cement ntawm cov pob zeb sib xyaw, peb pom zoo kom siv Portland cement, Portland cement, slag Portland cement, pozzolanic Portland cement, ya tshauv Portland cement thiab composite Portland cement. Cov lus qhia sov: peb yuav tsum zoo dua xyuas qhov kev hloov pauv ntawm cov khoom sib xyaw thiab cov cement ua ntej siv.

4. Cov ntaub ntawv siv rau kev siv cov khoom sib xyaw ua ke yuav tsum tau ua raws li cov qauv tam sim no. Thaum kev sim sib xyaw ua ke sib xyaw ua ke, peb yuav tsum siv cov khoom siv raw rau qhov project, raws li qhov tseeb ntawm qhov project.

5. Thaum siv ntau hom admixtures, tshwj xeeb yuav tsum tau them nyiaj rau lawv cov kev sib raug zoo thiab kev cuam tshuam ntawm kev ua tau zoo. Kev xaiv cov khoom sib xyaw ua ke tau hais meej dua, uas qhia nws qhov tseem ceeb thiab vam tias yuav pab tau rau txhua tus.
