Light ultra-high performance concrete based on pre-wetted spherical pottery sand and preparation method of light ultra-high performance concrete
The invention discloses light ultra-high performance concrete based on pre-wetted spherical pottery sand. The light ultra-high performance concrete is prepared from the following components in parts by weight: 730 to 750 parts of Portland cement, 480 to 500 parts of pre-wetted spherical pottery sand, 175 to 190 parts of silica fume, 185 to 200 parts of fly ash hollow microspheres, 20 to 25 parts of hybrid fibers, 11 to 15 parts of a composite additive, 5 to 10 parts of an expanding agent and 200 to 240 parts of water, the composite admixture is compounded by taking a polycarboxylic acid water reducer, a water-retaining agent, an air entraining agent, cellulose ether, a silicon resin polyether emulsion and water as main raw materials; the hybrid fibers comprise fine copper-plated steel fibers and polypropylene fibers. The lightweight ultra-high performance concrete disclosed by the invention has good pumping, lightweight, high strength and durability, the bearing capacity of a building structure is effectively improved, the section size of a component is reduced, and the service life of the building structure is prolonged; and the related preparation method is relatively simple, relatively low in cost and suitable for popularization and application.
本发明公开了一种基于预湿球形陶砂的轻质超高性能混凝土，各组分及其所占重量份数包括：硅酸盐水泥730～750份，预湿球形陶砂480～500份，硅灰175～190份，粉煤灰空心微珠185～200份，混杂纤维20～25份，复合外加剂11～15份，膨胀剂5～10份，水200～240份；所述复合外加剂以聚羧酸减水剂、保水剂、引气剂、纤维素醚、硅树脂聚醚乳液和水为主要原料复合而成；混杂纤维包括微细镀铜钢纤维和聚丙烯纤维。本发明所述轻质超高性能混凝土可兼顾良好的泵送、轻质、高强和耐久性能，有效提升建筑结构承载能力、减小构件截面尺寸延长建筑结构服役寿命；且涉及的制备方法较简单、成本较低，适合推广应用。
