Problems solved by technology

However, waste concrete aggregates have lower density, higher water absorption and lower strength than ordinary aggregates.
On the one hand, due to the fact that there is more cement mortar attached to the surface of the recycled aggregate, and the strength of the cement mortar is low, the strength of the recycled agg

Embodiment Construction

[0024] The implementation steps of the present invention are as follows:

[0025] (1) The concrete recycled aggregate is crushed by the waste concrete through the crusher, and then the sundries other than concrete are sorted, and then passed through the mesh screen to screen out the recycled coarse aggregate with the size between 5mm and 30mm, and clean it with clean water. After washing, let it dry naturally.

[0026] (2) ABS / PC plastic granules are regenerated from waste plastics.

[0027] (3) Steel fiber, recycled ABS / PC plastic particles, concrete recycled aggregate, natural coarse aggregate, sand, cement, and water are mixed in proportion to prepare steel fiber ABS / PC plastic recycled aggregate concrete as shown in Table 1. The properties of fiber ABS / PC plastic recycled aggregate concrete specimens are shown in Table 2.

Abstract

The invention discloses a preparation method for steel fiber ABS/PC plastic reclaimed aggregate concrete, which comprises the following steps of smashing, separating, sieving, cleaning and drying waste building concrete to obtain reclaimed concrete aggregate; smashing waste ABS/PC plastics to obtain reclaimed ABS/PC plastic particles; and then stirring steel fibers, reclaimed ABS/PC plastic particles, reclaimed concrete aggregate, natural coarse aggregate, sand, cement and water in proportion. The toughness, rupture strength, compression strength, impact resistance and other properties of the reclaimed aggregate concrete can be effectively improved by steel fiber modification; the reclaimed ABS/PC plastic particles can improve the anti-cracking performance, thermal insulation performance, wear-resisting performance and compression strength of the concrete; and the production of the material can reduce the environment pollution and improve the performance of the material without increasing cost.

Description

technical field [0001] The invention belongs to construction engineering materials, and in particular relates to a concrete preparation method obtained by mixing steel fibers, ABS / PC plastic particles and concrete recycled aggregates in proportion. Background technique [0002] The research and development of recycled concrete technology is to realize the recycling and utilization of construction waste, form new concrete products and then use them in buildings, so it is considered to be the most effective measure to solve construction waste. On the one hand, it can greatly reduce the amount of waste concrete that is landfilled and simply piled up, solving the problem that waste concrete is difficult to handle and pollutes the environment; on the other hand, the use of construction waste instead of natural aggregate can reduce the continuous mining of natural aggregate. , reduce the increasingly serious environmental problems caused by the over-exploitation of natural sand an...
