High-strength lightweight porous concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses high-strength light porous concrete and a preparation method thereof. The high-strength lightweight porous concreteis prepared from the following raw materials in parts by weight: 350-400 parts of cement, 700-800 parts of sand, 1100-1200 parts of stones, 170-230 parts of a mineral admixture, 220-280 parts of water, 20-30 parts of coarse whiting, 25-40 parts of straw fibers, 15-30 parts of kaolin, 5=10 parts of a foaming agent, 12=18 parts of a tackifier, 4=8 parts of expanded perlite and 3=5 parts of a waterreducing agent. The mineral admixture is prepared from the following raw materials in parts by weight: 50-70 parts of steel slag, 30-50 parts of fly ash and 90-110 parts of slag; the preparation method comprises the following steps: fully foaming the foaming agent through a foaming machine, and uniformly mixing the foam with cement paste to prepare the high-strength light porous concrete. According to the concrete, closed foam holes are formed in the concrete so that the lightweight effect is achieved, and the added straw fibers and mineral admixtures can improve the mechanical strength of theconcrete.
本申请涉及混凝土的技术领域，具体公开了一种高强轻质多孔混凝土及其制备方法。一种高强轻质多孔混凝土，由包含以下重量份的原料制成：水泥350‑400份、砂子700‑800份、石子1100‑1200份、矿物掺合料170‑230份、水220‑280份、重钙20‑30份、秸秆纤维25‑40份、高岭土15‑30份、发泡剂5‑10份、增粘剂12‑18份、膨胀珍珠岩4‑8份以及减水剂3‑5份；所述矿物掺合料由以下重量份的原料制成：钢渣50‑70份、粉煤灰30‑50份以及矿渣90‑110份；其制备方法为：通过发泡机将发泡剂充分发泡，然后将泡沫与水泥浆均匀混合，制备出高强轻质多孔的混凝土。本申请的混凝土，通过在混凝土内部形成封闭的泡沫孔，从而达到轻质的效果，加入的秸秆纤维和矿物掺合料能够提高混凝土的力学强度。
