| titleOfInvention | Frost crack resistant concrete and preparation method thereof |
| abstract | The invention relates to frost crack resistant concrete and a preparation method thereof, wherein the concrete comprises the following components in parts by weight: 380 parts of cement, 190 parts of water, 25-35 parts of expanding agent, 750 parts of fine aggregate, 1100 parts of coarse aggregate, 950-3.5 parts of water reducing agent, 2.5-3 parts of reinforcing fiber and 5.5-6 parts of anti-freezing agent, wherein the cross section of the reinforcing fiber is X-shaped; the preparation method comprises the following steps: 1) respectively adding the cement, the expanding agent, the fine aggregate, the coarse aggregate and the antifreeze into a stirrer, and uniformly stirring; 2) adding a water reducing agent into water, uniformly stirring to obtain a mixed solution, adding the mixed solution into a stirrer, and stirring for 1-2 min; (3) and (3) uniformly scattering the reinforced fibers into a stirrer, stirring for 4-6 minutes, and then casting, molding and curing. Compared with the prior art, the frost crack resistance of the concrete prepared by the invention is greatly improved compared with that of the common frost crack resistance concrete, and the problems of easy corrosion, easy agglomeration during stirring, difficult construction, poor acid and alkali resistance and the like of the common frost crack resistance steel fiber concrete are avoided. |
