Ultra-high performance concrete and preparation process thereof
The invention relates to the field of concrete, and particularly discloses ultra-high performance concrete and a preparation technology thereof.The concrete is prepared from cement, glass beads, mineral powder, silica fume, fine aggregate, water, a water reducing agent, steel fibers, an expanding agent, modified nano-porous carbon fibers, magnesium slag powder and a casein-water absorption composition; the modified nano-porous carbon fibers are obtained by soaking nano-porous carbon fibers in a cesium sulfate solution and then modifying the nano-porous carbon fibers; the casein-water absorption composition is obtained by mixing casein, a chitosan-based water absorption polymer and genipin; the preparation process comprises the following steps: mixing the cement, the glass beads, the mineral powder, the silica fume and the fine aggregate, and adding the expanding agent, the magnesium slag powder and the casein-water absorption composition; and dissolving the water reducing agent in water, adding the water reducing agent, adding the steel fibers and the modified nano-porous carbon fibers in batches, and adding the residual water to obtain the ultra-high performance concrete. The ultra-high performance concrete has the characteristics that the self-constriction value of the ultra-high performance concrete is improved, and meanwhile, the ultra-high performance concrete has higher mechanical strength.
本申请涉及混凝土领域，具体公开了超高性能混凝土及其制备工艺，混凝土包括以下原料：水泥、玻璃微珠、矿粉、硅灰、细骨料、水、减水剂、钢纤维、膨胀剂、改性纳米多孔碳纤维、镁渣粉以及干酪素‑吸水组合物；改性纳米多孔碳纤维由纳米多孔碳纤维经过硫酸铯溶液浸泡后改性得到；干酪素‑吸水组合物由干酪素和壳聚糖基吸水聚合物以及京尼平混合得到；其制备工艺包括以下步骤：将水泥、玻璃微珠、矿粉、硅灰和细骨料混合，加入膨胀剂、镁渣粉和干酪素‑吸水组合物；将减水剂溶解于水中加入，将钢纤维和改性纳米多孔碳纤维分次加入，加入剩余水，得到超高性能混凝土。本申请具有改善超高性能混凝土的自收缩值，同时具有更高的力学强度的特点。
