Pumpable normal-temperature-curing ultra-high-performance cement-based composite material
The invention relates to the technical field of construction materials, and discloses a pumpable normal-temperature-curing ultra-high-performance cement-based composite material which comprises a component A, a component B and a component C. The component A comprises the following components in parts by weight: 270-480 parts of cement, 8-40 parts of nano titanium dioxide, 330-600 parts of quartz powder, 10-100 parts of gypsum, 50-200 parts of ground fly ash and 100-150 parts of silica fume. The component B comprises 70-230 parts by weight of steel fibers, and the component C comprises the following components in parts by weight: 15-20 parts by weight of a superplasticizer, 10-20 parts by weight of a retarder and 100-125 parts by weight of water. According to the pumpable normal-temperature-curing ultra-high-performance cement-based composite material, the biological erosion resistance of the cement-based composite material is improved through the nano titanium dioxide, the compactness of the cement-based material can be improved through the nano titanium dioxide, and the water-binder ratio is reduced by adopting the active base material and the polycarboxylic acid water reducing agent with good compatibility with the active components.
本发明涉及建工材料技术领域，且公开了一种可泵送常温养护超高性能水泥基复合材料，包括A组份、B组份和C组份，所述A组份包括以下重量份的组份：水泥270～480重量份、纳米二氧化钛8～40、石英粉330～600重量份、石膏10～100重量份、磨细粉煤灰50～200重量份、硅灰100～150重量份，所述B组份钢纤维，钢纤维70～230重量份，所述C组份包括以下重量份的组份：高效减水剂15～20重量份、缓凝剂10～20重量份、水100～125重量份。该可泵送常温养护超高性能水泥基复合材料，通过纳米二氧化钛提高了水泥基复合材料的抗生物侵蚀性能，纳米二氧化钛可以增大水泥基材料的密实度，采用活性基材及与活性组分相容性良好的聚羧酸类减水剂，以降低水胶比。
