Environment-friendly high-strength quick-hardening concrete and preparation method thereof
The embodiment of the invention provides environment-friendly high-strength quick-hardening concrete and a preparation method thereof. The environment-friendly high-strength quick-hardening concrete is prepared from the following raw materials in parts by weight: 35-80 parts of a cementing material which comprises 27-60 parts of a quick-hardening cementing material and 8-20 parts of a geopolymer cementing material; 20 to 65 parts by weight of aggregate; 0.50 to 2.42 parts by weight of an additive; and 9-13 parts by weight of water. The environment-friendly high-strength quick-hardening concrete provided by the embodiment of the invention can be more compactly filled into cracks and more quickly coagulated and hardened under the flowability of the concrete, so that the concrete is tightly bonded with original concrete of a structure, and a crack repairing filler with relatively good compression resistance, fracture resistance and bonding strength is formed. Therefore, when the environment-friendly high-strength quick-hardening concrete is used as a crack repairing filler, time can be better gained in the process of repairing cracks in emergency, so that concrete cracks can be effectively repaired in a short time, the repaired concrete has high strength performance, and secondary damage is avoided.
本申请实施例提供了一种环保型高强快硬混凝土及其制备方法，该环保型高强快硬混凝土包括以下重量份数的原料：胶凝材料35～80重量份，胶凝材料包括快硬性胶凝材料27～60重量份、地聚合物胶凝材料8～20重量份；骨料20～65重量份；外加剂0.50～2.42重量份；水9～13重量份。本申请实施例提供的该环保型高强快硬混凝土可以在自身的流动性下更密实地填充入裂缝中并更快地凝结硬化，从而与结构物原有的混凝土粘结紧密，形成具有较好的抗压、抗折和粘结强度的裂缝修补填充物。可见，应用该环保型高强快硬混凝土作为裂缝修补填充物，可以更好地在抢险修补裂缝的过程中争取时间，以有效地在短时间内修补混凝土裂缝，并使修补混凝土具有高强性能，避免二次破坏。
