Abstract

The invention relates to a common cement micro-foaming modified additive and a micro-foaming concrete mixture. The physical foaming powder mainly exerts a physical foaming effect, the physical foamingaction time is short, and the foam is easily collapsed. Aluminum sulfate and light calcium carbonate mainly exert a chemical foaming effect, the chemical foaming action time is long and the foam is easily expanded. The chemical foaming and the physical foaming are simultaneously started, and after the physical foaming action time is over, the chemical foaming still continues acting, and can be used for expanding the collapsed foam in the foaming spheres formed by using the physical foaming. Sodium dodecyl benzene sulfonate can be used to promote foaming for formation of sufficient foaming spheres, and zinc stearate exerts an effect of thickening to inhibit the foaming expanding phenomenon in the chemical foaming, so that the formed foamed spheres are stable. Calcium stearate, soluble sodium aluminate and sodium aluminate can be used to shorten the condensation time of the concrete, so that the foaming spheres can be fixed. The complexity of the foaming process in the prior art is reduced, and the problems that the foaming sphere body is uneven in size and density of the foaming spheres are solved.

Description

technical field [0001] The invention relates to the technical field of ordinary Portland cement modifiers, in particular to an ordinary cement micro-foaming modification additive and a micro-foaming concrete mixture. Background technique [0002] The existing lightweight concrete foaming technology is usually used in chemical foaming method or physical foaming method. Chemical foaming is easy to expand, which will lead to excessive foaming pores and reduced bulk density, but at the same time will cause the strength of lightweight concrete to decrease. The problem of physical foaming is easy to collapse, which will lead to too small foaming pores and increased bulk density, but at the same time it will cause the problem that lightweight concrete is no longer light; the simple use of chemical foaming methods or physical foaming methods cannot balance Lightness and strength contradict each other. In the prior art, the method of first physical foaming followed by chemical foami...
