Study on Foaming Agent Foam Ability and Stability for Foam Concrete

Abstract:

Foam ability and stability of foaming agent are key factors for foam concrete properties. Through researching LAS, SDS and magnesite foaming agent commercially available, the results show that adding HPMC after can reduce LAS, SDS and magnesite foam bleeding quantity and subsidence distance and has little impact on foam expansion, magnesite foam ability and stability are inferior to LAS and SDS. LAS performance is the best, when the dilution ratio is 1:50 with 0.12% HPMC after, the foam expansion is 28.1 and bleeding is 14ml, subsidence distance is 5mm, the prepared foam concrete strength is 1.14MPa and dry density is 449kg/m³.
