Due to the irregular shape of the diamond material, there are many concave angles and rough surfaces, the resin bond has a stronger holding force on the abrasive material than ordinary diamond, so under the same grinding parameters, compared with ordinary diamond grinding wheels, the self-sharpening diamond grinding wheel has a grinding ratio increased by more than 60%. And since the interior of t...

Self-healing concrete is a new type of concrete. It imitates the automatic healing of body wounds by the secretion of some kind of material. To create self-healing concrete, some special materials (such as fibers or capsules), which contain some adhesive liquids, are dispensed into the concrete mix. When cracks happen, the fibers or capsules will break and the liquid contained in them will then he...

Fresh concrete is an unset mixture made by mixing cement, sand and coarse aggregate with water. The workability of fresh concrete is a comprehensive index, such as fluidity, pumpability, filling, uniformity, etc. The workability of a concrete mix is the relative ease with which concrete can be placed, compacted and finished without separation or segregation of the individual materials. Workability...

Diamond powder is mainly divided into single crystal diamond powder and polycrystalline diamond powder. Single crystal diamond powder is produced from synthetic diamond single crystal abrasive grains, which are crushed and shaped, and produced by a special process. Polycrystalline diamond powder is made from graphite using a unique directional blasting method. The shock wave of the directional bla...

The development of concrete technology has a history of more than 170 years. During the slow development process, there have been several changes. The discovery of the water-cement ratio theorem in 1919, the discovery of air-entraining agents in 1938, and the emergence of superplasticizers in the early 1960s. At present, the development of concrete technology is in a period of change. The emergenc...
