| titleOfInvention | Concrete with fine aggregate |
| abstract | The invention belongs to the technical field of concrete, and particularly discloses concrete with fine aggregate, which consists of a cementing material, coarse aggregate, fine aggregate, a water reducing agent and water; the mixing amount of the fine aggregate is 15-23%; the fine aggregate is composed of limestone powder, butyl stearate, silicon powder and fine sand; the mixing amount of the silicon powder among the fine aggregates is 10 to 20 percent; the fine aggregate is used for replacing medium and coarse sand in an equal volume, and the silicon powder is used for replacing cement in an equal mass. The invention particularly discloses a modified concrete prepared by proportioning fine aggregate with good performance and then replacing natural medium-coarse sand. The product has better improvement on the durability of concrete. The method can obtain the mixture with good fluidity, segregation resistance and less bleeding by using less water adding amount, and can obtain uniform and compact concrete under corresponding forming conditions, thereby achieving the purpose of saving cement and protecting the environment. |
