Lub teeb yuag qhob admixture.

Lightweight concrete is a type of concrete that weighs less than conventional concrete due to the use of low density aggregate. Aggregates used in lightweight concretes include pumice, tuff, scoria, diatomite and cinders.

Light weight concrete admixture is a special additive used in lightweight concrete to improve certain properties. Some admixtures are designed to reduce the amount of water needed for mixing and others can improve the compressive strength of lightweight concrete.

In general, lightweight concrete admixture increases the density of concrete, decreases the specific gravity, improves tensile and compressive strengths, and reduces the shrinkage of concrete. It can also enhance the flexural properties of concrete and the resistance of steel reinforcements to corrosion.

Yuav ua tau zoo rau kev sib xyaw pob zeb sib xyaw yog xaiv cov pob zeb sib xyaw kom raug. Cov no yuav tsum muaj qhov khoob tsawg, tab sis muaj qhov qhib siab.

Cov pob zeb me me no tuaj yeem tau los ntawm ntau qhov chaw xws li kev khawb pob zeb, cov khoom siv los ntawm kev tsim khoom, lossis qhov chaw khawb xuab zeb thiab pob zeb. Qee cov pob zeb sib xyaw uas pom ntau yog pumice, tuff, scoria, cinders, thiab shale uas tau ua tiav.

Muaj ob hom pob zeb me me lightweight concrete admixture, ib hom yog pob zeb gas concrete thiab lwm hom yog pob zeb ua npuas npuas. Hom thawj yog tsim los ntawm kev tso pa me me rau hauv batch mix los ntawm kev tshuaj lom neeg, hos hom thib ob siv pob zeb ua npuas uas muaj cua.

lightweight concrete admixture uas feem ntau ntxiv thaum sib xyaw thiab tom qab ntawd muab rau hauv qhov chaw. Vim cov khoom sib xyaw no ua haujlwm tsis tau yooj yim, Nws tseem ceeb heev kom siv lub twj tso kua mis uas tsis nrov dhau lossis ua rau muaj kev cais tawm.
