High-performance concrete with ultrahigh strength and toughness and preparation method thereof
The invention belongs to the technical field of concrete, and provides ultrahigh-strength and ultrahigh-toughness high-performance concrete and a preparation method thereof.The ultrahigh-strength and ultrahigh-toughness high-performance concrete is prepared from, by mass, 500-600 parts of cement, 40-60 parts of mineral powder, 90-110 parts of microbeads, 40-60 parts of silica fume, 490-500 parts of II-zone medium sand, 340-355 parts of 5-10 mm gravel, 800-815 parts of 10-20 mm gravel, 20-30 parts of additives, 40-50 parts of fibers and 110-120 parts of water; 5-6 parts of a compacting agent; 8-15 parts of a polycarboxylic acid water reducing agent; 10-25 parts of epoxy resin; the additive is prepared from N-n-butyl-N-methylethanolamine and dodecyl benzene sulfonic acid triethanolamine according to the mass ratio of 1 to (0.4 to 0.6). According to the invention, the concrete formula is improved, so that the compactness and toughness of the concrete are improved, and meanwhile, the concrete can meet the C120 compressive strength requirement, and the breaking strength of the concrete is also improved.
本发明属于混凝土技术领域，提出了一种超高强韧性高性能混凝土及其制备方法，按质量份数计，原料包括：500‑600份水泥，40‑60份矿粉，90‑110份微珠，40‑60份硅灰，490‑500份Ⅱ区中砂，340‑355份5‑10mm碎石，800‑815份10‑20mm碎石，20‑30份外加剂，40‑50份纤维，110‑120份水；5‑6份密实剂；8‑15份聚羧酸减水剂；10‑25份环氧树脂；所述外加剂包括质量比为1：0.4‑0.6的N‑正丁基‑N‑甲基乙醇胺和十二烷基苯磺酸三乙醇胺。本发明中通过对混凝土配方的改进，提高了混凝土的密实性、韧性性能，同时使得混凝土既可以满足C120抗压强度要求，同时还提高了其抗折强度。
