C15 concrete with excellent carbonization resistance and shrinkage performance
The invention relates to the technical field of concrete, in particular to concrete. The C15 concrete provided by the invention is prepared from the following components in parts by mass: 100 to 150 parts of cement, 80 to 160 parts of coal gangue powder, 60 to 100 parts of other admixtures, 170 to 180 parts of water, 1030 to 1040 parts of stones, 840 to 845 parts of sand and 6.0 to 7.0 parts of a water reducing agent, the other admixtures comprise waste brick powder and/or steel slag powder; the specific surface area of the coal gangue powder is 400-450m < 2 >/kg, the specific surface area of the waste brick powder is 500-550m < 2 >/kg, and the specific surface area of the steel slag powder is 300-350m < 2 >/kg. According to the record of the embodiment, the C15 concrete disclosed by the invention has good workability and plasticity, and the compressive strength, carbonization resistance and shrinkage resistance all accord with related national standards.
本发明涉及混凝土技术领域，尤其涉及一种混凝土。本发明提供的C15混凝土，按照质量份数计，包括以下组成：水泥100～150份，煤矸石粉80～160份，其他掺合料60～100份，水170～180份，石子1030～1040份，砂840～845份和减水剂6.0～7.0份；所述其他掺合料包括废砖粉和/或钢渣粉；所述煤矸石粉的比表面积为400～450m2/kg，所述废砖粉的比表面积为500～550m2/kg，所述钢渣粉的比表面积为300～350m2/kg。根据实施例的记载，本发明所述的C15混凝土具有良好的工作性和可塑性，抗压强度、抗碳化性能和抗收缩性能均符合相关国家标准。
