Desert sand concrete for prefabricated part and prefabricated part
The invention discloses desert sand concrete for a prefabricated part and the prefabricated part. The desert sand concrete for the prefabricated part comprises the following raw materials in parts byweight: 145-170 parts of water, 240-300 parts of cement, 70-90 parts of fly ash, 1000-1060 parts of coarse aggregate, 140-175 parts of desert sand, 600-680 parts of medium sand, 4-6 parts of a water reducing agent and 5-10 parts of a lubricant. According to the technical scheme provided by the invention, the cement, the fly ash, the coarse aggregate, the medium sand, the desert sand, the lubricantand the water reducing agent are compounded according to a certain proportion, so that the compressive strength of the concrete is ensured; and medium sand is partially replaced by desert sand, so that the raw material cost of the concrete for the prefabricated part is reduced, and the concrete is environment-friendly and has extremely high economic benefits.
本发明公开一种预制件用沙漠砂混凝土以及预制件，所述预制件用沙漠砂混凝土包括如下重量份数的原料：水145～170份、水泥240～300份、粉煤灰70～90份、粗骨料1000～1060份、沙漠砂140～175份、中砂600～680份、减水剂4～6份以及润滑剂5～10份。本发明提供的技术方案中，通过将水泥、粉煤灰、粗骨料、中砂、沙漠砂、润滑剂以及减水剂按一定的份量复配，保证了混凝土的抗压强度；通过使用沙漠砂部分取代中砂，降低了预制件用混凝土的原料成本，环保且具有极高的经济效益。
