| titleOfInvention | Super-dispersion-resistant and segregation-resistant concrete and preparation method and construction process thereof |
| abstract | The invention discloses super-dispersion-resistant and segregation-resistant concrete and a preparation method and a construction process thereof, and relates to the technical field of building materials. The super-dispersion-resistant and segregation-resistant concrete comprises the following concrete raw materials: 80-160 parts of cement, 70-150 parts of water, 5-12 parts of a water reducing agent, 1.5-3.5 parts of prenyl polyoxyethylene ether and 1.2-2 parts of 2-acrylamide-2-methylpropanesulfonic acid; the concrete raw materials also comprise concrete powder and modified sepiolite fibers, and the concrete powder comprises: 200 portions of crushed stone, 350 portions of sand and 250 portions of coal ash and 220 portions of coal ash; the modified sepiolite fiber comprises: sepiolite fibers, praseodymium nitrate and 2-hydroxyethyl trimethylammonium chloride. It has the advantage of good crack resistance. The preparation method comprises the following steps: mixing materials, preparing concrete and the like. The preparation method has the advantage of improving the cracking resistance of the product. |
