Cement-based modified composite material and preparation method thereof
The invention provides a cement-based modified composite material. The cement-based modified composite material comprises the following components in parts by weight: 300-550 parts of Portland cement;200-400 parts of slag; 50-500 parts of incineration fly ash; 1-7 parts of a polycarboxylate superplasticizer; 0.5-1 part of a water-absorbing polymer; and 192-580 parts of water; according to the cement-based modified composite material, Portland cement, slag and incineration fly ash are used as main components and cooperate with a water-absorbing polymer and a polycarboxylate superplasticizer, so that heavy metal ions are effectively absorbed into the water-absorbing polymer and retained in the water-absorbing polymer, the curing effect is achieved, and meanwhile, the leaching process of theheavy metal ions is slowed down; the precipitation concentration of heavy metals in the composite material is greatly reduced by the water-absorbing polymer, and the performance of the molecular structure of the cement-based modified composite material is improved, so that the cement-based modified composite material reaches the use standard of building materials.
本申请提供了一种水泥基改性复合材料，所述水泥基改性复合材料包括如下重量份的下列组分：300～550份硅酸盐水泥；200～400份矿渣；50～500份焚烧飞灰；1～7份聚羧酸减水剂；0.5～1份吸水性聚合物；192～580份水；该水泥基改性复合材料以硅酸盐水泥、矿渣、焚烧飞灰为主要组分，协同吸水性聚合物和聚羧酸减水剂，使重金属离子被有效吸收进入吸水性聚合物内部，并被滞留在内部，达到固化效果，同时缓重金属离子浸出的过程；使得吸水性聚合物大幅降低复合材料中重金属的析出浓度并提高水泥基改性复合材料的分子结构的性能，使该水泥基改性复合材料达到建材使用的标准。
