High-strength concrete with fire resistance and burst resistance and preparation method thereof
The invention relates to the technical field of building materials, and particularly discloses high-strength concrete with fire resistance and burst resistance and a preparation method of the high-strength concrete. The high-strength concrete with fire resistance and burst resistance is prepared from the following components in parts by weight: 250 to 300 parts of cement, 120 to 180 parts of fly ash, 90 to 120 parts of mineral powder, 950 to 1000 parts of coarse aggregate, 820 to 860 parts of fine aggregate, 7 to 11 parts of a water reducing agent, 115 to 125 parts of water, 10 to 20 parts of a high-temperature tackifier, 20 to 32 parts of a ceramic composite material and 18 to 36 parts of a high-temperature reinforcing material. The high-temperature tackifier comprises polyamide resin, paraffin and polystyrene in a mass ratio of 1: (0.3-0.5): (0.5-1). The high-strength concrete with fire resistance and burst resistance has the advantages of high compressive strength and good fire resistance and burst resistance.
本申请涉及建筑材料技术领域，具体公开了一种具有耐火性和防爆裂性的高强混凝土及其制备方法。具有耐火性和防爆裂性的高强混凝土包括以下重量份的组分：250‑300份水泥、120‑180份粉煤灰、90‑120份矿粉、950‑1000份粗骨料、820‑860份细骨料、7‑11份减水剂、115‑125份水、10‑20份高温增粘剂、20‑32份陶瓷复合材料、18‑36份高温增强材料；所述高温增粘剂包括质量比为1:0.3‑0.5：0.5‑1的聚酰胺树脂、石蜡和聚苯乙烯。本申请的具有耐火性和防爆裂性的高强混凝土具有抗压强度大，耐火性和防爆裂性好的优点。
