Ardealite solid waste foam concrete and preparation method thereof
The invention discloses an ardealite solid waste foam concrete. The concrete comprises, by weight, 50-70 parts of ardealite, 10-20 parts of ordinary Portland cement, 40-50 parts of slag, 20-30 parts of modified bentonite, 10-20 parts of activated carbon nanotubes, 1-2 parts of a water reducing agent, 0.1-0.3 part of a foaming agent, 1-3 parts of a foam stabilizer, 35-40 parts of coarse aggregate, 25-35 parts of fine aggregate and 35-40 parts of water. According to the embodiment 1-2, the 28-day strength can reach 24.8 MPa, the heat conduction coefficient is 0.21 w/(m.K), the linear shrinkage rate is 0.11%, meanwhile, no modified bentonite is added, the activated carbon nanotubes are not subjected to thermal activation treatment, and the performance of the concrete can be reduced.
本发明公开了一种磷石膏固体废弃物泡沫混凝土，包括以下重量份的原料：磷石膏50‑70份、普通硅酸盐水泥10‑20份、矿渣40‑50份、改性膨润土20‑30份、活化碳纳米管10‑20份、减水剂1‑2份、发泡剂0.1‑0.3份、稳泡剂1‑3份、粗骨料35‑40份、细骨料25‑35份、水35‑40份。本发明实施例1‑2的28天强度可高达24.8MPa，导热系数为0.21w/(m·K)，线性收缩率为0.11%，同时未加入改性膨润土、活化碳纳米管未采用热活化处理，混凝土的性能都会下降。
