Abstract:
The relationship between porosity and compressive strength of foamed mixture lightweight concrete with different density and water-binder ratio is investigated for foamed mixture lightweight concrete of 600 kg/cm3 and 800 kg/cm3 densities for engineering fields. The results show that the average pore size of foamed lightweight concrete increases with increasing water-binder ratio; the average pore size of foamed lightweight concrete decreases with increasing density grade,and the average pore size changes about 24.5%~25.4%,and the porosity changes about 2.8%~16.6% with the density grade of foamed lightweight concrete increasing from 600 kg/cm3 to 800 kg/cm3; the compressive strength of the foamed lightweight concrete increases with increasing water-binder ratio,and then decreases.
