Phosphogypsum-based anti-freezing mortar
The invention relates to the field of mortar, and discloses ardealite-based anti-freezing mortar which comprises the following components in parts by weight: 100 parts of cement; 45 to 55 parts of water; 4-5 parts of silica fume; 40 to 50 parts of slag; 0.8 to 1.2 parts of a gypsum retarder; the mass ratio of the modified ardealite powder coated with the nano montmorillonite powder to the cement is (1.2-1.5): 1. The silica fume and the slag supplement the strength of the mortar, and the nano montmorillonite powder can fill gaps in the mortar and improve the connection tightness of the cement and the modified phosphogypsum, so that a large amount of phosphogypsum is conveniently doped under the condition of ensuring certain strength, the phosphogypsum is rapidly consumed, and the storage cost and environmental pollution of the phosphogypsum are reduced.
本申请涉及砂浆的领域，公开一种磷石膏基抗冻砂浆，包括以下重量份的组分：水泥100份；水45‑55份；硅灰4‑5份；矿渣40‑50份；石膏缓凝剂0.8‑1.2份；纳米蒙脱石粉末包覆的改性磷石膏粉末，纳米蒙脱石粉末改性磷石膏粉末与水泥的质量比为(1.2‑1.5)：1。硅灰和矿渣补充砂浆的强度，并且纳米蒙脱石粉末能够填充砂浆内间隙，提高水泥和改性磷石膏的连接紧密度，从而方便在保证一定强度的条件下，大量的掺入磷石膏，从而快速消耗磷石膏，减少磷石膏的储存成本和环境污染。
