Technical Field

[0001] The utility model relates to the technical field of concrete, in particular to a concrete forming device for testing. Background Art

[0002] Concrete, abbreviated as "concrete," is a general term for engineering composite materials composed of aggregates bonded together by a cementitious material. The term "concrete" generally refers to cement as the binder, sand and stone as aggregates, mixed with water (which may contain admixtures and additives) in a specific proportion, and then mixed. Cement concrete, also known as ordinary concrete, is widely used in civil engineering. During the construction and civil engineering process, building materials or components often need to be transported to the site for preparation. For example, during the concrete molding process, molds are often assembled on-site, then the concrete is transported from the mixing plant to the site and poured into the molds to form the concrete.

[0003] Before concrete is put into use, it must first be tested. During the concrete forming process, the experimental concrete forming device pours the concrete into the mold and then places the formed concrete in the observation box for observation. The existing preparation mold is mostly a whole, which makes it inconvenient to take out the formed test block, easily causing the test block to break, resulting in low test result accuracy and inconvenience in cleaning the inner wall of the mold.

[0004] Therefore, it is necessary to invent a kind of experimental concrete forming device to solve the above problems. Utility Model Content
