Experimental Study on Preparation of Foam Concrete by Camellia Meal Green Foaming Agent

Abstract

Abstract: The green foaming agent was prepared by water extraction method with natural plant tissue camellia meal as raw material, and the foam concrete was prepared by physical foaming method. The effects of mixing time, water-binder ratio and foam content on the dry density, compressive strength and pore structure of foam concrete were investigated. The results show that the green foaming agent has high foam stability and can be used to prepare low-density foam concrete, so it is a high-quality new green foaming agent. When the foam content is 750 mL, the mixing time is 180 s, and the water-binder ratio is 0.45, the water absorption of the prepared A05 density grade foam concrete is 45%, and the compressive strength is 1.52 MPa. The foam concrete prepared by green foaming agent has uniform pore size distribution, small pore size (maximum pore size d_max<0.6 mm), and complete pore morphology.

Key words: camellia meal, green foaming agent, foam concrete, physical foaming, microscopic pore structure, pore size distribution
