Expanding agent containing modified phosphate tailing concrete and preparation method thereof
The invention is suitable for the field of building materials, and discloses an expanding agent containing modified phosphate tailing concrete and a preparation method of the expanding agent. Comprising the following components in parts by weight: 45-50 parts of modified phosphate tailings, 10-15 parts of anhydrite powder, 20-25 parts of waste ceramic powder and 10-25 parts of water-quenched slag powder. The concrete expansive agent is simple in raw material source, low in cost and capable of remarkably reducing shrinkage of the concrete volume and improving the anti-cracking and anti-seepage performance of the concrete.
本申请适用于建筑材料领域，公开了一种含有改性磷尾矿混凝土的膨胀剂及其制备方法，含有改性磷尾矿混凝土的膨胀剂包括所述膨胀剂以重量份数计算,包括以下组分：改性磷尾矿45‑50份、硬石膏粉10‑15份、废弃陶瓷粉20‑25份、以及水淬矿渣粉10‑25份。本申请的混凝土膨胀剂原材料来源简单、成本较低，能够显著减小混凝土体积的收缩，提高混凝土的抗裂抗渗性能。
