Composite admixture for foamed concrete and preparation method and application thereof
The invention discloses a composite admixture for foamed concrete and a preparation method and application thereof. The admixture comprises the following raw materials by weight: 82-90 parts of zirconium-silicate slag, 4-6 parts of calcium nitrate, 3-10 parts of calcium stearate, and 0.5-2 parts of a water reducer. The invention has the following beneficial effects: (1) simple production and application technology; (2) obvious effects of adjusting thickening, foam stabilization and foam solidification; (3) significant coagulation promotion, early strength and shortened production cycle; (4) significantly increased effect, addition of 2%-8% of foamed concrete into the admixture, no autoclave curing or heat curing requirement, strength reaching or exceeding that of the autoclaved aerated concrete masonry block of a same density grade in national standard after maintenance for 7d in natural conditions; and (5) utilization of zirconium silicon slag of 100%, no secondary by-products, waste utilization and environmental protection.
