In engineering, the quality of materials is an important factor to ensure the safety and stability of the project. This paper will introduce the related contents of product quality to help readers better understand how to ensure the engineering quality.

defective goods

Unqualified products include unqualified final setting time, fineness and strength lower than the grade index stipulated by the commodity, etc. These products can be used in secondary engineering, but not in civil engineering.

waste

Waste products include unqualified initial setting time, unqualified stability test (F-Cao), excessive F-MgO content, excessive SO3 content and strength below the minimum strength grade. Waste products are strictly prohibited for civil engineering.

Strictly control the quality of materials

In engineering, we need to strictly control the quality of materials to avoid unqualified or waste products. Only by ensuring the stability and reliability of material quality can the safety and stability of the project be guaranteed.
