Ultra-high performance concrete and preparation method thereof
The invention belongs to the technical field of concrete, and particularly relates to ultra-high performance concrete and a preparation method thereof. The invention provides ultra-high performance concrete, which is prepared from the following components in parts by mass: 600 to 650 parts of cement, 150 to 180 parts of stone powder, 120 to 150 parts of silica fume, 100 to 450 parts of ardealite aggregate, 510 to 1140 parts of sand grains, 30 to 35 parts of water reducing agent, 150 to 160 parts of steel fiber and 120 to 160 parts of water. The ardealite aggregate is adopted to replace sand grains, so that the addition amount of the sand grains can be reduced on the basis of ensuring the mechanical strength and avoiding cracking.
本发明属于混凝土技术领域，具体涉及一种超高性能混凝土及其制备方法。本发明提供了一种超高性能混凝土，以质量份数计，包括以下组分：水泥600～650份、石粉150～180份、硅灰120～150份、磷石膏骨料100～450份、砂粒510～1140份、减水剂30～35份、钢纤维150～160份和水120～160份。本发明采用磷石膏骨料代替砂粒，能够在保证力学强度和避免开裂的基础上降低砂粒的添加量。
