Khoom noj: Cov huab cua nkag mus rau thaj tsam ntawm 5% mus rau 8% ntawm qhov ntim ntawm pob zeb. Cov dej txo qis tau dhau los ua qhov tseem ceeb hauv cov pob zeb, uas lawv tuaj yeem suav tias yog "thib tsib" cov khoom xyaw. Lawv tuaj yeem siv rau: (1) nce slump, (2) txo cov dej-cement piv, lossis (3) txo cov ntsiab lus cement.
Dab tsi yog qhov piv ntawm cov khoom sib xyaw hauv pob zeb?
Cov feem pua ntawm Sikament-163, uas tau ntxiv rau hauv cov pob zeb sib xyaw, yog0 % (ib txwm ua vaj tse), 0.75 %, 1 %, 1.25 %, 1.5 %, 1.75 %, 2% thiab 2.5% los ntawm cement hnyav. Kev tshawb fawb yog ua los ntawm kev siv cuaj cov qauv kuaj rau txhua feem pua ntawm Sikament-163 nrog tib qhov poob qis.
Yuav ua li cas yog qhov sib xyaw ua ke feem pua suav?
Calculation of Sand & Coarse Aggregate Quantities:
Admixture=1.2% by weight of cement=5.064 kg.
Dab tsi yog qhov feem pua siab tshaj ntawm cov khoom sib xyaw hauv pob zeb?
Los ntawm daim duab 3, peb tuaj yeem pom tias qhov siab tshaj plaws lossis qhov zoo tshaj plaws rau cov khoom sib xyaw yog 1.0%i.e, 1000 ml / 100kg ntawm cov cement uas tau los ntawm cov qauv S4. Lub zog compressive txo qis yog tias qhov ntau npaum li cas ntawm SP hloov pauv piv txwv li, siab dua lossis qis dua ntawm qhov txwv no.
Yuav ua li cas yog cov khoom siv hauv pob zeb?
Admixtures yog ntxiv rau kev sib xyaw ua ke uas tuaj yeem pab tswj lub sijhawm teem thiab lwm yam ntawm cov pob zeb tshiab. Common admixtures muaj xws li nrawm admixtures, retardingAdmixtures, ya tshauv, cua nkag admixtures, thiab dej-txo admixtures.
