Problems solved by technology

[0002] A large amount of waste stone and stone powder will be produced during the construction, maintenance or demolition of construction projects. The disposal of these waste stone or stone powder has become an urgent problem. The traditional method is to landfill the waste stone or stone paste powder, which is undoubtedly is a waste of resources
[0003] Foamed concrete block, also known as foamed concrete, is to introduce gases such as air into the concrete slurry by chemical or physical means, and form a concrete product containing a large number of holes and having a certain strength through molding and curing; the foamed concrete of the prior art Autoclave steam curing is often required in the block production process, and the concrete blocks formed by autoclaving are less stable, and the process wastes a lot of energy and pollutes the environment.
