Lightweight wall special-purpose cell concrete, and production method thereof
The invention discloses a lightweight wall special-purpose cell concrete, and a production method thereof. The production method comprises following steps: (1) rapid hardening sulphoaluminate cement, ordinary Portland cement, and dry discharge fly ash are delivered into a double helix conical mixer so as to obtain a composite cementing agent via premixing; (2) water, cold-water-soluble polyvinyl alcohol powder, polypropylene reinforcing fiber, calcium stearate water repellent, a silane coupling agent, expanded perlite, and polyphenyl foam particle are delivered into an agitator; (3) the composite cementing agent obtained via step (1) is delivered into the agitator, and micropore foam prepared from a micropore foaming agent via compressed air is sprayed into the agitator, an uniform slurry is obtained via mixing stirring, and slurry volume weight is controlled to be 1000 to 1200kg/m3; (4) the uniform slurry is pumped into lightweight wall products or cast-in-situ wall forming moulds; and (5) finished products are obtained via curing, hardening, moulding, and demoulding. The lightweight wall special-purpose cell concrete can be used for producing various lightweight wall products and cast-in-situ lightweight concrete walls, and is an ideal material used for producing energy-saving lightweight walls and products.
