Problems solved by technology

[0003] Due to the fact that the recycled aggregate particles prepared by simple crushing and screening process of construction waste have many edges and corners, the surface is rough, and the components also contain hardened cement mortar. A large number of microcracks lead to large porosity, high water absorption, low bulk density, large porosity, and high crushing index of the recycled aggregate itself. The recycled concrete prepared by this recycled aggregate has a large amount of water and low strength after hardening. The elastic modulus is low, and the durability properties such as impermeability, frost resistance, carbonation resistance, shrinkage, creep and chloride ion penetration resistance are lower than ordinary concrete made of natural aggregates. Therefore, in order to obtain compression resistance Regenerated bricks with high strength and hardness, it is necessary to develop a kind of construction waste slag recycled floor tiles and its preparation method

Description

technical field [0001] The invention belongs to the technical field of energy-saving building materials, and in particular relates to a floor tile regenerated from building waste slag and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy, there are countless construction wastes produced by the demolition of old buildings every year in the country. Building energy conservation is imperative, and it is also an important part of sustainable economic development. Recycling of construction solid waste Utilization not only achieves the purpose of energy saving, but also helps to protect the environment and maintain the natural ecological balance. Therefore, it is a good and effective means to use construction waste to make recycled floor tiles for resource reuse. [0003] Due to the fact that the recycled aggregate particles prepared by simple crushing and screening process of construction waste have many edges and corner...
