Abstract
Description
Technical Field
[0001] The utility model relates to the field of concrete, in particular to a concrete raw material proportioning device. Background Art
[0002] The term concrete generally refers to cement as the binder, sand and stone as aggregates, and water (which may contain admixtures and additives) mixed in a specific proportion.
