Abstract

The invention discloses a preparation method of regenerated fiber composite active ore material reinforced recycled concrete. The concrete is prepared from, by weight, 10-20 parts of plastic particles, 100-200 arts of concrete coarse aggregate, 50-100 parts of blinding, 10-20 parts of cement, 10-20 parts of sand, 5-10 parts of coal ash, 5-10 parts of activated water and 10-20 parts of water. The preparation method comprises the following steps of selection of plastic products, smashing of waste concrete, mixing of the raw materials, preparation of the concrete and discharging of the concrete.According to the preparation method of the regenerated fiber composite active ore material reinforced recycled concrete, the plastic products and the waste concrete are smashed separately, and then the smashed material is mixed with the blinding, the cement, the sand, the coal ash, the water and the activated water to generate modified concrete; the concrete is low in cost and raw material cost, reduces energy consumption and reduces the pollution to the environment, and through addition of the activated water, the bearing capacity of the prepared concrete is improved.

Description

technical field [0001] The invention relates to the technical field of concrete preparation, in particular to a preparation method of recycled fiber composite active mineral material reinforced recycled concrete. Background technique [0002] For a long time, sand and gravel aggregates have been considered as an inexhaustible raw material due to their wide availability and low price. With the rapid development of the construction industry, the demand for sand and gravel aggregates continues to increase. Due to the long-term disorderly and random mining, the sand and gravel aggregate resources are constantly being exhausted, causing the rapid development of the construction industry and the contradiction of resource shortage will become more and more prominent. However, at the same time, with the development of urbanization and the construction industry With the rapid development of China's rapid development, construction waste is piled up like mountains. The traditional exte...
