C50-grade pumping fiber concrete

The invention discloses C50-grade pumping fiber concrete, and relates to the technical field of power grid infrastructure engineering, and the C50-grade pumping fiber concrete comprises the following components by mass: 450 parts of cement; 125 parts of desert sand; 162 parts of water; 1162 parts of coarse aggregate; 4.5 parts of a water reducing agent; 500 parts of natural sand; 9 parts of fiber. The cement, the fiber, the desert sand, the water, the coarse aggregate, the water reducing agent and the natural sand are proportioned according to the mass components, so that the 28d strength and the cubic splitting tensile strength of the C50-grade pumping fiber concrete can be improved, and the slump of the concrete is reduced. 本发明公开一种C50级泵送纤维混凝土，涉及电网基建工程技术领域，所述C50级泵送纤维混凝土以质量配比以下组分：水泥450份；沙漠砂125份；水162份；粗骨料1162份；减水剂4.5份；天然砂500份；纤维9份。本发明通过采用水泥、纤维、沙漠沙、水、粗骨料、减水剂、天然砂按照质量组分配比，可以提高C50级泵送纤维混凝土的28d强度及立方体劈裂抗拉强度，降低混凝土的塌落度。
