Abstract

The invention discloses a foam concrete formula and a preparation process thereof. The foam concrete is prepared from the following components in parts by weight: 5 to 10 parts of Portland cement clinker, 10 to 20 parts of fly ash, 10 to 20 parts of stone powder or mineral powder or construction waste powder, 2 to 3 parts of acrylic acid, 7 to 9 parts of water, 0.1 to 0.2 part of a composite foaming agent, 1.5 to 3 parts of an exciting agent, 0.2 to 0.4 part of a thickening agent, 4 to 5 parts of aggregate, 6 to 10 parts of silica fume, 2 to 10 parts of calcium chloride, 1 to 5 parts of activated carbon and 2 to 5 parts of foam. According to the foam concrete disclosed by the invention, the silica fume and the calcium chloride are added in the preparation process of the foam concrete, so that the setting and hardening time of the foam concrete can be effectively shortened, meanwhile, the activated carbon is added in the preparation process of the foam concrete, so that water molecules generated during fusion can be adsorbed in the fusion preparation process; the water cement ratio and free moisture in a concrete mixture are reduced, and the hardness of the set and hardened foam concrete is improved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a foam concrete formula and a preparation process thereof. Background technique [0002] Foamed concrete is to fully foam the foaming agent mechanically through the foaming system of the foaming machine, and evenly mix the foam with the cement slurry, and then go through the pumping system of the foaming machine for cast-in-place construction or mold molding. A new type of lightweight insulation material containing a large number of closed pores formed by curing; however, in the process of preparing foam concrete, the hardness of foam concrete after preparation is low, and the setting and hardening time of foam concrete is longer. , for this purpose, we propose a foam concrete formulation and its preparation process. Contents of the invention [0003] The object of the present invention is to provide a foam concrete formula and its preparation process, which solves the proble...
