The invention relates to the field of concrete, in particular to concrete suitable for a high-temperature construction environment and a preparation method of the concrete. The concrete suitable for the high-temperature construction environment is prepared from the following raw materials in parts by mass: 185 to 205 parts of cement, 70 to 150 parts of mineral admixture, 130 to 160 parts of water, 650 to 710 parts of fine aggregate, 1100 to 1300 parts of coarse aggregate, 3 to 8 parts of water reducing agent, 25 to 40 parts of rice hull ash, 25 to 40 parts of pineapple leaf fiber and 5 to 15 parts of boron carbide, the preparation method comprises the following steps: uniformly mixing the cement and the mineral admixture to obtain a dry mixture; adding water, rice hull ash, pineapple leaf fiber and boron carbide into the dry mixture, and uniformly mixing to obtain a mixture; and adding the fine aggregate, the coarse aggregate and the water reducing agent into the mixture, and uniformly mixing to obtain the concrete. The method has the advantage that the influence of high temperature on the concrete strength is relieved.
本申请涉及混凝土领域，更具体地说，它涉及一种适用于高温施工环境下的混凝土及其制备方法。一种适用于高温施工环境下的混凝土，按照质量份数，包括以下原料：185‑205份水泥、70‑150份矿物掺合料、130‑160份水、650‑710份细骨料、1100‑1300份粗骨料、3‑8份减水剂、25‑40份稻壳灰、25‑40份菠萝叶纤维、5‑15份碳化硼；其制备方法为：将水泥、矿物掺合料混合至均匀，得到干混料；往干混料内加入水、稻壳灰、菠萝叶纤维、碳化硼，混合至均匀，得到混合料；往混合料内加入细骨料、粗骨料、减水剂、混合至均匀，得到混凝土。本申请具有缓解高温对混凝土强度的影响的优点。
