Ultrahigh-toughness concrete and preparation method thereof
The invention discloses an ultrahigh-toughness concrete comprising the raw materials: cement, water-borne epoxy resin emulsion, polypropylene fibers, silica fume, clay ceramsite, an expanding agent, a polycarboxylic acid high-efficiency water reducing agent, a polyamine curing agent, triethylene tetramine, methyl methacrylate and polyvinyl alcohol fibers. The mass ratio of the cement to the water-borne epoxy resin emulsion to the polypropylene fibers to the silica fume to the clay ceramsite to the expanding agent to the polycarboxylic acid high-efficiency water reducing agent to the polyamine curing agent to the triethylene tetramine to the methyl methacrylate to the polyvinyl alcohol fibers is (20-40):(1-4):(4-8):(1-5):(2-8):(1-2):(1-2):(0.1-1):(2-6):(1-3):(1-4). The particle size of the clay ceramsite is 5-16 mm, the apparent density is 1200-1500 kg/m<3>, the bulk density is 700-1100 kg/m<3>, and the cylinder compressive strength is greater than or equal to 6.5 MPa.
本发明公开了一种超高韧性混凝土，其原料包括：水泥、水性环氧树脂乳液、聚丙烯纤维、硅灰、粘土陶粒、膨胀剂、聚羧酸高效减水剂、多元胺固化剂、三乙烯四胺、甲基丙烯酸甲酯、聚乙烯醇纤维；水泥、水性环氧树脂乳液、聚丙烯纤维、硅灰、粘土陶粒、膨胀剂、聚羧酸高效减水剂、多元胺固化剂、三乙烯四胺、甲基丙烯酸甲酯、聚乙烯醇纤维的质量比为20‑40：1‑4：4‑8：1‑5：2‑8：1‑2：1‑2：0.1‑1：2‑6：1‑3：1‑4。粘土陶粒的粒径为5‑16mm，表观密度为1200‑1500kg/m3，堆积密度为700‑1100kg/m3，筒压强度≥6.5MPa。
