Abstract
The invention discloses a waste concrete module. The module uses a recycled concrete aggregate which is formed by crushing, screening and mixing according to certain ratio, cement and water as production raw materials. Due to taking the recycled concrete aggregate as the raw material, the module of cuboid, circular arc-shaped, right angle or other shapes can be produced. By adjusting the ratios of components of the recycled concrete aggregate, the ratio between the recycled concrete aggregate and the cement or the grain diameter of the recycled concrete aggregate, the module with different strength levels can be produced. The recycled concrete aggregate is used as the raw material to produce the waste concrete module, which not only recovers and utilizes the waste concrete, but also lowers the production cost of the module.
Description
Technical field
The present invention relates to a kind of material of construction that utilizes building waste to produce, specifically, the present invention relates to a kind of building slab that adopts waste and old concrete as raw material production.
Background technology
Produce a large amount of waste and old concretes in construction project construction, maintenance or the demolishing process; In addition, utilize in the concrete production building slab process and can form a large amount of waste product, substandard products and defective material, also produce a large amount of waste and old concretes, the processing of these waste and old concretes has become a urgent problem.Traditional way is abandoned these waste and old concretes as rubbish, this is undoubtedly a kind of waste.In " building waste is handled and resource utilization " book of Chemical Industry Press's publication in 2004, once mentioned the resource utilization problem of waste and old building concrete, after the fragmentation of waste concrete block process, cleaning, classification, form Aggregate of recycled concrete according to certain mixed.But the recovery of Aggregate of recycled concrete and utilization remain the problem that faces in building waste processing and the resource utilization process.In addition, because natural resource are tending towards exhausted, utilize traditional sand, stone, cement etc. also more and more higher as the cost of raw material production building block.
