Qhuav mix qhob, tseem hu ua qhuav-mix qhob los yog qhuav-sib tov mortar, yog ib tug pre-mixed mix ntawm cement, xuab zeb, thiab lwm yam additives uas yog tov nrog dej rau ntawm qhov chaw los tsim ib tug paste zoo li cov khoom uas yuav siv tau rau. ntau yam kev siv kev tsim kho. Qhov sib piv ntawm cov khoom xyaw hauv cov pob zeb qhuav qhuav yog qhov tseem ceeb rau kev ua tiav qhov xav tau lub zog, ua haujlwm tau zoo, thiab ua haujlwm ntev ntawm cov khoom kawg. Nyob rau hauv tsab xov xwm no, peb yuav tham txog ntau yam khoom ntawm qhuav mix qhob thiab qhov ratios siv nyob rau hauv nws ntau lawm.

Cheebtsam ntawm Dry Mix Concrete:

Cov khoom tseem ceeb ntawm cov pob zeb qhuav qhuav muaj xws li cov cement, xuab zeb, thiab lwm yam khoom ntxiv. Cov hom tshwj xeeb ntawm cov khoom siv ntxiv yog nyob ntawm qhov kev npaj siv ntawm cov pob zeb, tab sis lawv feem ntau suav nrog cov tshuaj tua kab mob uas txhim kho kev ua haujlwm, teeb tsa lub sijhawm, thiab lub zog ntawm cov khoom kawg.

Cement:

Cement yog qhov sib txuas tus neeg sawv cev hauv pob zeb uas muab nws lub zog thiab kav ntev. Cov hom cement feem ntau siv rau hauv cov pob zeb qhuav qhuav yog Portland cement, uas yog tsim los ntawm kev sib xyaw ntawm limestone, av nplaum, thiab lwm yam minerals uas tau muab rhaub kom kub kom tsim tau cov hmoov zoo. Lwm hom cement, xws li cov cement dawb lossis siab alumina cement, kuj tseem siv tau rau hauv cov ntawv tshwj xeeb.

Xuab zeb:

Xuab zeb yog siv rau hauv pob zeb los muab ntim thiab txo cov nqi sib tov. Hom xuab zeb siv hauv cov pob zeb qhuav yog feem ntau cov xuab zeb ntse, uas yog tsim los ntawm crushed granite los yog lwm yam pob zeb nyuaj. Qhov loj thiab cov duab ntawm cov xuab zeb hais txog kev ua haujlwm thiab lub zog ntawm cov khoom kawg.

Additives:

Cov khoom siv ntxiv yog siv rau hauv cov pob zeb qhuav qhuav los txhim kho nws cov khoom, xws li kev ua haujlwm, teeb tsa lub sijhawm, thiab lub zog. Cov additives feem ntau muaj xws li plasticizers, uas txhim kho kev ua haujlwm ntawm kev sib tov, accelerators, uas ua kom lub sijhawm teem sijhawm, thiab cov dej reducers, uas txo cov dej xav tau rau qhov sib tov.

Qhov ratio ntawm cov khoom xyaw nyob rau hauv qhuav Mix pob zeb:

Qhov sib piv ntawm cov khoom xyaw hauv cov pob zeb qhuav sib txawv nyob ntawm qhov kev npaj siv ntawm cov pob zeb, qhov xav tau lub zog, thiab lwm yam xws li hom xuab zeb thiab cement siv. Cov feem ntau siv nyob rau hauv qhuav mix qhob yog:

1. Standard Mix:

Cov txheej txheem sib xyaw rau cov pob zeb qhuav yog qhov sib piv ntawm 1: 2: 3 ntawm cov cement, xuab zeb, thiab aggregate (pob zeb lossis gravel). Qhov sib tov no yog siv rau kev siv dav dav xws li flooring, plastering, thiab bricklaying.

2. Mix Hindiaz :

Kev sib xyaw ua kom muaj zog yog siv thaum lub pob zeb xav tau los tiv thaiv cov khoom hnyav lossis kev kub ntxhov. Qhov sib tov no feem ntau muaj qhov sib piv ntawm 1: 1.5: 3 ntawm cov cement, xuab zeb, thiab sib sau ua ke.

3. Fiber Reinforced Mix:

Kev sib xyaw fiber ntau yog siv thaum xav tau lub zog tensile ntxiv hauv cov pob zeb. Qhov sib xyaw no feem ntau muaj qhov sib piv ntawm 1: 2: 3 ntawm cov cement, xuab zeb, thiab sib xyaw, nrog rau kev sib ntxiv ntawm fibers xws li hlau, nylon, lossis polypropylene.

4. Fast-Setting Mix:

Kev sib xyaw ceev ceev yog siv thaum lub pob zeb xav tau teeb tsa sai. Qhov sib xyaw no feem ntau muaj qhov sib piv ntawm 1: 2: 2 ntawm cov cement, xuab zeb, thiab sib sau ua ke, nrog rau kev sib ntxiv ntawm cov accelerators kom ceev lub sijhawm teem sijhawm.

5. Waterproof Mix:

Kev sib xyaw dej tsis sib haum yog siv thaum lub pob zeb xav tau dej-resistant. Qhov sib xyaw no feem ntau muaj qhov sib piv ntawm 1: 2: 3 ntawm cov cement, xuab zeb, thiab sib sau ua ke, nrog rau kev sib ntxiv ntawm cov dej tsis zoo xws li latex lossis acrylic.

Mixing Dry Mix Concrete:

Cov pob zeb qhuav qhuav yog sib xyaw los ntawm kev ntxiv cov khoom xyaw ua ntej sib xyaw rau hauv ib lub khob los yog lub thoob thiab tom qab ntawd ntxiv cov dej uas tsim nyog. Tus nqi ntawm cov dej ntxiv rau qhov sib tov yog nyob ntawm qhov xav tau sib xws ntawm cov pob zeb. Tom qab ntawd cov sib tov yog tov kom txog thaum nws yog homogeneous thiab tsis muaj lumps. Nws yog ib qho tseem ceeb uas yuav tsum tau ua raws li cov chaw tsim khoom cov lus qhia rau kev sib tov thiab siv qhov sib piv ntawm cov khoom xyaw kom ntseeg tau tias qhov xav tau lub zog thiab sib xws ntawm cov khoom kawg.
