Abstract

Nowadays, foam concrete is widely used in construction. However, the structure and properties of foam concrete with a density < 1200 kg/m3 are greatly affected by different foaming agents. In this study, the effects of foaming agents (EABASSOC and AS) on the properties of foam concrete are presented such as compressive strength, flexural strength, shrinkage, water absorption, thermal insulation and microstructure. Research results show that EABASSOC foaming agent has better stability and durability than AS foaming agent; compressive strength of foam concrete using EABASSOC foaming agent is higher from 0.7÷1.1 MPa and water absorption is lower than foam concrete using AS foaming agent from 2.1÷6%. In addition, the pore structure of the foam concrete was tested by electron microscopy (SEM). Foamed concrete using EABASSOC foaming agent showed a narrower pore size distribution in concrete than using AS foaming agent. It can be proved that using EABASSOC foaming agent to produce foam concrete brings many practical meanings in the construction in Vietnam.
