Inona avy ireo karazana simenitra maivana

What is lightweight concrete？

Beton maivana dia matetika ampiasaina amin'ny trano injeniera maro, ary ny simenitra maivana dia manondro ny simenitra vita amin'ny akora sy simenitra maivana sy maivana. Ny simenitra maivana dia teny ankapobeny ho an'ny simenitra manana hakitroky betsaka tsy mihoatra ny 1950kg/m3. So what types of lightweight concrete are included?

There are three main types of lightweight concrete

1. Lightweight aggregate concrete has an apparent density of 800~1950 kg/m3. Lightweight aggregates include pumice, volcanic slag, ceramsite, expanded perlite, expanded slag, tain-drendrika, sns.

2. Hollow concrete (simenitra foamed, aerated concrete), its apparent density is 300-1000 kg/m3. Foamed concrete is made of cement slurry or cement mortar and stable foam. Aerated concrete is made of cement, water and gas generating agent.

3. Macroporous concrete (ordinary macroporous concrete, light aggregate macroporous concrete) has no fine aggregate in its composition. The apparent density of ordinary macroporous concrete ranges from 1500 ny 1900 kg/m3, and is prepared with crushed stone, soft stone, and heavy slag as aggregates. The apparent density of light aggregate macroporous concrete is 500-1500 kg/m3, and it is prepared with ceramsite, pumice, broken brick, tain-drendrika, sns. as aggregates.
