Embodiment 1

[0007] Embodiment 1: the concrete composition of the present invention is made up of water, cement, sand, coal ash, strengthening agent, blowing agent; Mass ratio is between the above-mentioned composition: water: blowing agent=1: 30, cement: strengthening agent= 100:0.6, cement: coal ash: sand = 5:3:2, the required fly ash must not have large particles and agglomerates, and the cement uses ordinary Portland cement No. 42.5, and all materials after mixing and proportioning are fully Stir evenly, pour into shape, and then keep it moist for curing. The diameter of the pores of the foamed concrete is 0.5mm-0.7mm, the pores are closed and unconnected, the shape of the pores is close to spherical, and the diameter is uniform and moderately dense.

Embodiment 2

[0008] Embodiment 2: the specific composition of the present invention is made up of water, cement, ceramsite, coal ash, strengthening agent, blowing agent; This invention process step is: the mass ratio between the above-mentioned components is: water: blowing agent=1: 30. Cement: reinforcing agent = 100:1, cement: coal ash: sand = 5:3:2, the required fly ash must not have large particles and agglomerates, and the cement should be ordinary portland cement No. 42.5. All the materials after mixing and proportioning are fully stirred evenly, cast into shape, and then kept moist for curing treatment. The pore diameter of the finished foam concrete is 0.8mm-1.0mm, the pore is closed and unconnected, the shape of the pore is close to spherical, and the diameter Even and moderately dense.

[0009] Through the above-mentioned embodiments, the foamed concrete is tested in terms of dry bulk density, wet bulk density, strength grade, and slump. The detection results are as follows:

Abstract

The invention relates to a process for preparing waterproof foam concrete. The waterproof foam concrete comprises the specific components of water, cement, sand, coal ash, a reinforcing agent and a foaming agent, wherein the mass ratio of the water to the foaming agent is 1:30, the mass ratio of the cement to the reinforcing agent is 100:1-0.8, and the mass ratio of the cement to the coal ash to the sand is 5:3:2; the coal ash is required not containing large particles and cakes, and ordinary Portland cement NO.42.5 is suitably used as cement. The process comprises the following steps of: mixing all proportioned materials, fully stirring uniformly, pouring, molding, keeping wet and maintaining. The foam concrete prepared by the process has strong waterproofing and heat-insulating properties, flame retardance, small deformation coefficient, light volume weight, strong earthquake resistant property, good endurance, low production cost, low elasticity and excellent shock-absorbing property.

Description

technical field [0001] The invention relates to a preparation process of concrete, in particular to a preparation process of waterproof foam concrete. Background technique [0002] At present, in order to promote wall reform and innovation, according to the research results of high-efficiency wall materials at home and abroad and the performance requirements of modern new buildings for building materials, an ideal wall material can be summarized, which must have good thermal insulation, heat insulation, and sound insulation. Good performance, good fire and flame retardancy, small deformation coefficient, good aging resistance, high durability, stable performance, simple construction, low cost, and at the same time meet the requirements of energy saving and environmental protection, and do not harm the human body and the environment during production and construction adverse effects, and can achieve recycling, but the existing technology can not meet the above-mentioned needs...
