Description

Technical Field

[0002] Concrete, simply referred to as "tóng", is a general term for engineering composite materials in which aggregate is cemented into a whole by a gelling material. Usually, the concrete mentioned refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as the gelling material, sand and stone as the aggregate, and water (which may contain additives and admixtures) in a certain proportion and then stirred. It is widely used in civil engineering. For example, a kind of concrete disclosed in the patent with the application number CN201610738626.1 is composed of the following parts by weight: 75 - 90 parts of cement, 50 - 55 parts of medium sand, 60 - 70 parts of crushed stones, 30 - 45 parts of waste calcined material, 5 - 11 parts of aggregate, 0.8 - 9.9 parts of sodium sulfite powder, and 150 - 180 parts of water;
