Embodiment Construction

[0016] The present invention will be further described below in conjunction with specific examples and experimental data.

[0017] A process for making permeable concrete from recycled aggregates from construction waste is characterized in that it comprises the following process steps:

[0018] 1) Mix the water with the weight ratio of 1:20 and the recycled aggregate evenly to obtain the wet material of the recycled aggregate;

[0019] 2) Mix the wetting material of recycled aggregate, cement, and sulfamate in a weight ratio of 105:10:1 to obtain a wrapping material wrapped with cement and sulfamate;

[0020] 3) Mix the wrapping material wrapped with cement and sulfamate, cement, and water with a weight ratio of 30:3:1 to obtain permeable concrete made of recycled aggregate from construction waste.

[0021] The performance comparison of the present invention relative to existing conventional technology:

Abstract

The invention discloses a process for making permeable concrete by building rubbish recycled aggregates, and relates to the technical field of building rubbish regeneration. The process includes the steps: 1) uniformly mixing water and the recycled aggregates to obtain wetting materials of the recycled aggregates; 2) mixing the wetting materials of the recycled aggregates, cement and addition agents to obtain wrapping materials wrapped with the cement and the addition agents; 3) mixing the wrapping materials wrapped with the cement and the addition agents, the cement and water to obtain the permeable concrete made of the building rubbish recycled aggregates. By the aid of a method of aggregate wrapped with mortar, namely, raw materials are added in batches and uniformly mixed, residual raw materials or parts of raw materials are then added, the surfaces of the recycled aggregates can be uniformly wrapped with cement slurry, the aggregates can be sufficiently adhered, and the strength and the permeable rate of the permeable concrete are improved.

Description

technical field [0001] The invention relates to the technical field of construction waste recycling, in particular to a process for preparing permeable concrete from construction waste recycled aggregates. Background technique [0002] Permeable concrete is composed of cement, water and coarse aggregate (may contain a small amount of fine aggregate). Generally, aggregates with specific particle sizes are used as the skeleton to form a porous accumulation structure. There are a large number of interconnected pores inside, which is similar to ordinary concrete. It has good air permeability and water permeability, which can effectively alleviate the "urban heat island effect" and reduce the phenomenon of heavy rain and waterlogging. [0003] The water absorption of natural aggregate is not as good as that of recycled aggregate, and the water storage coefficient of recycled aggregate from construction waste is more than twice that of natural aggregate. While saving resources, i...
