Copolyformaldehyde fiber reinforced ultra-high performance cement-based composite material and preparation method thereof
The invention relates to the technical field of building materials, in particular to a co-polyformaldehyde fiber reinforced ultra-high-performance cement-based composite material and a preparation method thereof.The co-polyformaldehyde fiber reinforced ultra-high-performance cement-based composite material is prepared from, by weight, 600-800 parts of cement, 160-440 parts of mineral admixture, 180-300 parts of superfine stone powder, 500-750 parts of fine aggregate, 600-900 parts of coarse aggregate, 11-22 parts of efficient water reducing agent, 120-198 parts of water and 7-28 parts of co-polyformaldehyde fiber; the length of the copolyformaldehyde fiber is 6-16 mm; according to the invention, the polyformaldehyde fiber is doped into the ultrahigh-performance cement-based composite material instead of steel fiber, so that the tensile strength and breaking strength of the ultrahigh-performance cement-based composite material can be improved, the ductility of the ultrahigh-performance cement-based composite material can be remarkably improved, and the high-temperature burst resistance of the ultrahigh-performance cement-based composite material can be enhanced; the concrete has very high practical value and popularization value in the technical field of high-performance concrete.
本发明涉及建筑材料技术领域，具体涉及一种共聚甲醛纤维增强超高性能水泥基复合材料及其制备方法，包括以下重量分数的原料：水泥600～800份，矿物掺合料160～440份，超细石粉180～300份，细骨料500～750份，粗骨料600～900份，高效减水剂11～22份，水120～198份，共聚甲醛纤维7～28份；共聚甲醛纤维长度为6～16mm；本发明将共聚甲醛纤维替代钢纤维掺入超高性能水泥基复合材料中，可提高超高性能水泥基复合材料的抗拉和抗折强度，显著改善超高性能水泥基复合材料的延性，增强其抗高温爆裂性能，在高性能混凝土技术领域具有很高的实用价值和推广价值。
