Ua li cas Foam Beton cuam tshuam rau lub zog ntawm cov pob zeb?

ua npuas ncauj yog ib lub pob zeb sib sib zog nqus uas muaj cua npuas thiab foamed cement slurry. Nws tau yog qhov kev xaiv nrov rau kev tsim kho vim nws xav tau cov khoom siv tsawg dua kom ua tiav tib lub zog. ua npuas ncauj kuj muaj qhov ntom ntom ntau dua li cov pob zeb tsoos, txo kev txhawj xeeb ntawm ib puag ncig.

Cov hom sib xyaw siv tuaj yeem muaj txiaj ntsig zoo rau lub zog ntawm cov pob zeb ua npuas ncauj. Piv txwv li, RCA tau pom tias ua kom lub zog compressive ntawm cov pob zeb ua npuas ncauj thaum hloov cov xuab zeb. Qhov no yog vim qhov khoob khoob ntawm RCA nce qhov porosity, ua rau kom zoo dua dej nqus. Cov tshuaj tiv thaiv pozzolanic ntawm FA ua rau muaj zog ntau dua thiab [2].

Ntxiv rau qhov sib sau ua ke, tus neeg sawv cev foaming tuaj yeem cuam tshuam qhov zoo ntawm ua npuas ncauj. Cov surfactant siv yuav tsum muaj peev xwm stabilizing ua npuas ncauj, thiab nws cov dilution piv yuav tsum tau txwv. Qhov no yuav tiv thaiv kev sib cais, thiab tseem pab kom muaj kev sib xyaw ua ke.

Ntau qhov kev tshawb fawb tau sim qhov ruaj khov ntawm cov pob zeb ua npuas ncauj. Ib qho kev sim ntsuas tau muab cov khoom sib txawv ntawm qhov hnyav thiab qhov loj me rau hauv beakers uas muaj cov protein thiab hluavtaws hluavtaws, ces ntsuas lub sij hawm uas nws coj mus rau lub pob rau tog. Cov txiaj ntsig tau pom tias ua npuas ncauj nrog cov protein ntau ruaj khov, thiab hais tias qhov qis dilution ratio yuav tsum tau ua kom tau raws li qhov sib xws.

Ntau cov khoom xyaw ntxiv tau kawm txog lawv cov teebmeem ntawm lub zog ntawm cov pob zeb ua npuas ncauj. Granulated blast furnace slag tau pom tias muaj txiaj ntsig zoo hauv kev kho tus nqi thiab tus nqi ntawm cov dej kub, nrog rau kev tswj qhov kub thiab txias nce thaum sib tov thiab kho. Qhov no ua rau kom muaj zog compressive thiab splitting tensile lub zog ntawm cov pob zeb ua npuas ncauj. Silica fume yog lwm cov tshuaj ntxiv uas muaj txiaj ntsig zoo rau lub zog ntawm cov pob zeb ua npuas ncauj.
