High-performance concrete for laminated slab, manufacturing method of high-performance concrete and laminated slab prepared from high-performance concrete
The invention discloses high-performance concrete for a laminated slab, a manufacturing method of the high-performance concrete and the laminated slab. The high-performance concrete is prepared from the following components in parts by weight: 490-510 parts of cement, 770-790 parts of coal ash, 450-460 parts of quartz sand, 9-11 parts of a water reducing agent, 300-305 parts of water and 15-17 parts of fibers, wherein the weight ratio of the cement to the coal ash to the quartz sand is (kg/m < 3 >) to the water reducing agent; the high-performance concrete is obtained by adding the fibers and mixing the cement, the fly ash, the quartz sand, the water reducing agent and the water according to a specific proportion, so that the compression resistance, the shear resistance and the crack resistance of the concrete are remarkably improved.
本发明公开了一种用于叠合板的高性能砼及其制作方法及其叠合板，所述高性能砼的重量配比按照kg/m3计：水泥490至510，粉煤灰770至790，石英砂450至460，减水剂9至11，水300至305，纤维15至17；本发明中通过加入纤维，并通过特定比例的水泥、粉煤灰、石英砂、减水剂和水进行拌合得到高性能砼，显著提高了砼本身的抗压、抗剪和抗裂能力。
