Abstract
In this paper, the influence of four main factors on the compressive strength of cement-based foam concrete is studied by orthogonal test with L_9 (3 ^ 4) orthogonal table. They are the amount of foam agent, the amount of water reducing agent, the amount of foam stabilizer and the water cement ratio. The results show that the main factors affecting the 7-day compressive strength of cement-based foam concrete are: water cement ratio > foam agent content > water reducer content > foam stabilizer content. The best test mix is: water cement ratio 0.41, foam agent 0.66%, water reducer 0.20%, foam stabilizer 0.021%. Its 7-day compressive strength is 2.65 MPa, dry density is 444 kg/m^3, water absorption rate is 23%, in line with JG/T 266-2011 “foam concrete” and JGJ/T 341-2014 “foam concrete application technical specification” stipulated in the performance requirements.
