Phosphogypsum lightweight high-ductility cement-based composite material and preparation method thereof
The invention discloses a phosphogypsum lightweight high-ductility cement-based composite material, and belongs to the technical field of building materials. The high-ductility cement-based composite material is prepared from the following raw materials in parts by weight: 450 to 600 parts of cement, 150 to 300 parts of fly ash, 100 to 300 parts of silica fume, 400 to 500 parts of phosphogypsum lightweight aggregate, 200 to 300 parts of elastic asphaltic sand, 12 to 18 parts of composite fiber, 60 to 90 parts of steel fiber, 20 to 30 parts of water reducing agent and 170 to 200 parts of water, the preparation method of the elastic asphaltic sand comprises the following steps: screening waste asphalt concrete to obtain waste asphaltic sand; the waste asphaltic sand is washed with an organic solvent, dried, soaked in industrial oil and dried, and the elastic waste asphaltic sand is obtained; the preparation method comprises the following steps: adding the elastic waste asphaltic sand into a mixed solution of water, a silane coupling agent and absolute ethyl alcohol to react, filtering and drying to obtain the elastic asphaltic sand. The light high-ductility cement-based composite material has the advantages of light weight, low shrinkage, high tensile strength and high impact strength.
本发明公开了一种磷石膏轻质高延性水泥基复合材料，属于建筑材料技术领域。本发明的高延性水泥基复合材料，包括以下重量份数的原料：水泥450‑600份，粉煤灰150‑300份，硅灰100‑300份，磷石膏轻质集料400‑500份，弹性沥青砂200‑300份，复合纤维12‑18份，钢纤维60‑90份，减水剂20‑30份，水170‑200份；其中，弹性沥青砂的制备方法，包括以下步骤：将废弃沥青混凝土筛分，得到废弃沥青砂；废弃沥青砂经有机溶剂冲洗，干燥后置于工业油中浸泡，干燥，得到弹性废弃沥青砂；将弹性废弃沥青砂加入水、硅烷偶联剂和无水乙醇的混合溶液中反应，过滤，干燥，得到所述弹性沥青砂。本发明的轻质高延性水泥基复合材料具有轻质、低收缩、高抗拉强度和高抗冲击强度的优点。
