Ultrahigh-strength light cement-based composite material and preparation method thereof
The invention discloses an ultrahigh-strength light-weight cement-based composite material and a preparation method thereof, and belongs to the technical field of building materials, the ultrahigh-strength light-weight cement-based composite material is composed of cement, silicon powder, ceramic hollow microspheres, water, a water reducing agent and copper-plated steel fibers, the water-binder ratio is 0.14, the total volume of the ultrahigh-strength light-weight cement-based composite material is taken as a reference, and the total volume of the ultrahigh-strength light-weight cement-based composite material is 1-5%. The silicon powder accounts for 9% of the total volume, and the copper-plated steel fiber accounts for 2% of the total volume. When the ultrahigh-strength light cement-based composite material is prepared, the added ceramic hollow microbeads play a dual effect, and the ceramic hollow microbeads are used as a light filler and an auxiliary cementing material. The steel fibers are added into the ultrahigh-strength light cement-based composite material, so that the cement-based composite material is good in toughness, not prone to shrinkage and good in durability. The hollow ceramic microbeads with low density are used as the filler, the density of the cement-based composite material is reduced to 1600kg/m < 3 >-1700kg/m < 3 >, the compressive strength is higher than 100MPa, and the two characteristics of high strength and light weight are balanced.
本发明公开了一种超高强轻质水泥基复合材料及其制备方法，属于建筑材料技术领域，所述超高强轻质水泥基复合材料由水泥、硅粉、陶瓷空心微珠、水、减水剂和镀铜钢纤维组成，水胶比为0.14，以超高强轻质水泥基复合材料的总体积为参考，硅粉为总体积的9％，镀铜钢纤维为总体积的2％。在制备的超高强轻质水泥基复合材料时加入的陶瓷空心微珠起到了双重效应，不仅作为了轻质填料，而且作为了辅助胶凝材料。本发明的超高强轻质水泥基复合材料中加入了钢纤维，水泥基复合材料韧性好、不易收缩，而且耐久性好。采用密度较低的空心陶瓷微珠作为填料，降低了水泥基复合材料的密度，密度降至1600kg/m3～1700kg/m3，抗压强度高于100MPa，平衡了高强度和轻质两特性。
