High-toughness high-cohesiveness C70 strength fiber concrete and preparation method thereof
The invention discloses high-toughness and high-cohesiveness C70 strength fiber concrete and a preparation method thereof. The concrete is prepared from cement, river sand, broken stone, fly ash, straw ash, silica fume, nano silicon, water, a water reducing agent, an exciting agent, a defoaming agent, a shrinkage reducing agent, ramie fiber, basalt fiber and CaCO3 whisker according to the mixing ratios of (350 to 360): (723): (1010): (105 to 112): (45 to 55): (14 to 17): (2 to 3.5): (155 to 160): (7.5 to 8.5): (12 to 13): (1.8 to 2.1): (6.8 to 7.8): (4.7 to 4.9): (7.9 to 8.1): (17.3 to 17.5). Through a layered stirring method, all the materials are uniformly mixed at intervals, and discharging, forming and curing are performed. The compression resistance, the fracture resistance, the splitting tensile strength, the toughness, the durability and the like of the concrete can be effectively improved, and the bonding strength and the cooperative deformation capacity between the concrete and profile steel are enhanced.
本发明公开了一种高韧高粘结性C70强度的纤维混凝土及其制备方法，混凝土配合比包括：水泥：河砂：碎石：粉煤灰：秸秆灰：硅灰：纳米硅：水：减水剂：激发剂：消泡剂：减缩剂：苎麻纤维：玄武岩纤维：CaCO3晶须＝350‑360：723：1010：105‑112：45‑55：14‑17：2‑3.5：155‑160：7.5‑8.5：12‑13：1.8‑2.1：6.8‑7.8：4.7‑4.9：7.9‑8.1：17.3‑17.5。通过分层搅拌法，将各材料间隔拌合均匀，出料、成型、养护。本发明混凝土的抗压、抗折、劈拉强度及韧性、耐久性能等能有效提高，并增强混凝土与型钢之间的粘结强度和协同变形能力。
