Quick-drying concrete material for pavement leakage stoppage and preparation method of quick-drying concrete material
The invention discloses a quick-drying concrete material for pavement plugging and a preparation method thereof. The quick-drying concrete material comprises the following components in parts by weight: 80-120 parts of Portland cement clinker; 30 to 60 parts of fly ash; 1-6 parts of a curing agent; 1-3 parts of a quick drying agent; 1-5 parts of a defoaming agent; 2-10 parts of calcium sulfate; 5-25 parts of an organic adhesive; 50-75 parts of fresh water; 120 to 200 parts of fine aggregate; 100 to 150 parts of coarse aggregate; 50 to 80 parts of glass particles; 10 to 40 parts of steel-polyolefin hybrid fiber; 1-5 parts of a thickening time control agent; and 1-5 parts of a flow regulator. The quick-drying concrete material has the advantage of being convenient to pour, and the problems that in the using process of an existing quick-drying concrete material for road surface leaking stoppage, the concrete setting time is too short, the flowability is low, the difficulty that a worker pours concrete into cracks is increased, the using strength and the bearing pressure of the concrete are low, and the service life of the concrete is prolonged are solved. And subsequent cracking and damage are easily caused.
本发明公开了一种用于路面堵漏的快干型混凝土材料及制备方法，按重量份计数包括以下成分：硅酸盐水泥熟料80‑120份；粉煤灰30‑60份；固化剂1‑6份；速干剂1‑3份；消泡剂1‑5份；硫酸钙2‑10份；有机粘连剂5‑25份；淡水50‑75份；细骨料120‑200份；粗骨料100‑150份；玻璃颗粒50‑80份；钢‑聚烯烃混杂纤维10‑40份；调凝剂1‑5份；流性调节剂1‑5份。本发明具备便于浇注的优点，解决了现有的用于路面堵漏的快干型混凝土材料在使用的过程中，混凝土的凝结时间过快以及流动性较低，增加了工作人员把混凝土浇注在裂缝内部的难度，以及混凝土的使用强度和承压力较低，容易导致后续开裂损坏的问题。
