High-strength, high-rigidity and high-toughness cement-based composite material and preparation method thereof
The invention discloses a cement-based composite material with high strength, high rigidity and high toughness. The cement-based composite material is prepared from the following raw materials in parts by mass: 1396 to 1543 parts of a cementing material, 274 to 303 parts of sand, 266 to 294 parts of water, 52 to 57 parts of a water reducing agent and 18 to 20 parts of fibers, the cementing material is selected from a mixture of 1330-1470 parts of cement and 70-78 parts of silica fume, and the mass of the silica fume accounts for 5% of that of the cementing material; the water-cement ratio of the cement-based composite material is below 0.2, and the sand ratio is below 0.4. The problem of brittleness of common concrete is solved; the problems that an existing ECC material is low in strength and rigidity are solved. The problem that quality control is difficult after mass production of an existing ECC material is solved.
本发明公开一种高强度高刚度高韧性的水泥基复合材料，该水泥基复合材料的原料质量份数配比包括：胶凝材料1396－1543份、砂子274－303份、水266－294份、减水剂52－57份、纤维18－20份；所述胶凝材料选自水泥1330－1470份和硅灰70－78份的混合物，其中硅灰质量占胶凝材料的5％；所述水泥基复合材料的水灰比在0.2以下，砂率在0.4以下。本发明解决普通混凝土脆性的问题；解决目前ECC材料强度低、刚度低的问题；解决目前ECC材料量产后品控困难的问题。
