Fireproof concrete and preparation method thereof
The invention relates to the field of building materials, and particularly discloses fireproof concrete and a preparation method thereof. The fireproof concrete is prepared from the following raw materials in parts by weight: 50 to 100 parts of cement, 200 to 300 parts of aggregate, 10 to 30 parts of refractory fiber, 15 to 30 parts of polyvinyl alcohol, 10 to 25 parts of polyolefin elastomer, 0.5 to 3 parts of water reducing agent and 40 to 80 parts of water, the preparation method comprises the following steps: S1, uniformly mixing the polyolefin elastomer with the polyvinyl alcohol and the refractory fibers in a molten state to prepare a standby material; and S2, uniformly mixing the standby material with a water reducing agent, adding cement, aggregate and water, and uniformly mixing to obtain the fireproof concrete. The fireproof concrete has relatively high compressive strength at high temperature.
本申请涉及建筑材料的领域，具体公开了一种防火混凝土及其制备方法。防火混凝土的制备原料按重量份计，包括水泥50‑100份、骨料200‑300份、耐火纤维10‑30份、聚乙烯醇15‑30份、聚烯烃类弹性体10‑25份、减水剂0.5‑3份、水40‑80份；其制备方法为：S1、将聚烯烃类弹性体在熔融状态下与聚乙烯醇、耐火纤维混合均匀制得备用料；S2、将备用料与减水剂混合均匀，后投入水泥、骨料和水混合均匀后制得防火混凝土。本申请的防火混凝土在高温下具有较高的抗压强度。
