Rice hull ash doped high-strength energy-saving dust-falling concrete and preparation method thereof
The invention provides rice hull ash doped high-strength energy-saving dust-falling concrete and a preparation method thereof, and belongs to the technical field of building materials. Comprising the following steps: S1, raw material preparation: taking the following raw materials in parts by weight: 300-360 parts of cement, 10-60 parts of rice hull ash, 630-640 parts of sand, 1200-1210 parts of stones, 210-260 parts of water and 2-4 parts of a water reducing agent; s2, mixing the raw materials: uniformly stirring and mixing the cement, the sand and the stones in parts by weight, adding the rice hull ash, uniformly stirring and mixing, then mixing the water and the water reducing agent, adding, and stirring until the concrete is thick; s3, preparing the high-strength energy-saving and dust-reducing concrete: after the materials mixed in the S2 are subjected to die filling, vibrating and forming, covering the surface with a waterproof thin film, performing thin film curing, removing the die, and performing standard curing, so as to obtain the high-strength energy-saving and dust-reducing concrete. The high-strength energy-saving dust-falling concrete is prepared by mixing the cement, the rice hull ash, the sand, the stones and the water according to a certain proportion, and the rice hull ash is doped, so that the compressive strength and the splitting tensile strength of the concrete are improved.
本发明提供了一种掺加稻壳灰的高强节能降尘混凝土及其制备方法，属于建筑材料技术领域。包括以下步骤：S1.原料准备：按重量份计取原料，水泥300‑360份、稻壳灰10‑60份、砂子630‑640份、石子1200‑1210份、水210‑260份和减水剂2‑4份；S2.原料混合：先将重量份计的水泥、砂子、石子搅拌混合均匀，加入稻壳灰搅拌混合均匀，然后将水和减水剂混合后加入，搅拌至混凝土呈稠和状；S3.制备高强节能降尘混凝土：将S2混合后的物料进行装模、振捣、成型后，表面覆盖不透水的薄膜进行薄膜养护后拆模进行标准养护，即得所述高强节能降尘混凝土。本发明的高强节能降尘混凝土由水泥、稻壳灰、砂子、石子、水按一定比例混合配置而成，其中稻壳灰的掺入，提高了混凝土的抗压、劈裂抗拉强度。
