The invention relates to the technical field of concrete, in particular to high-performance concrete. The high-performance concrete is prepared by the following steps: selecting materials, namely selecting composite Portland cement, fine sand, stones, fly ash, an air entraining agent, a water reducing agent, natural volcanic ash, silica fume, granite and other raw materials for later use; grinding: selecting 5kg of granite, stone, natural volcanic ash and other materials each time; crushing in a collision crusher; wherein the crushing sizes are 0.5 mm, 2 mm and 0.15 mm; placing and stacking the high-performance concrete in a classified manner after crushing. According to the present invention, the ratio of the composite Portland cement to the water is 1:3, such that the cement slurry is uniform after the cement is stirred, the stone, the fine sand, the natural volcanic ash and the like are gradually added so as to make the cement slurry more tightly mixed, and the gradually placed water reducing agent and other materials make the cement have a series of effects of high strength, permeation resistance, frost resistance and the like.
本发明涉及混凝土技术领域，尤其涉及一种高性能混凝土包括以下步骤：选料：选取复合硅酸盐水泥、细沙、石子、粉煤灰、引气剂、减水剂、天然火山灰、硅灰、花岗岩等原料进行备用；研磨:将花岗岩、石子、天然火山灰、等材料每次选取5公斤，放入碰撞粉碎机中进行破碎，破碎大小为0.5mm、2mm、0.15mm，破碎后分类放置堆积该高性能混凝土，通过复合硅酸盐水泥和水1比3的配比，使水泥搅拌后泥水均匀，后通过逐步添加石子、细沙、天然火山灰等，使水泥浆间混合的更加紧密，后通过逐步放置的减水剂等材料，使水泥具备强度高、抗渗、抗冻等一系列效果。
