Hardened concrete is concrete that must be sufficiently strong to withstand the structural and service applied loads and it must be durable enough for the environmental risk for which it is designed. It is the strongest and durable construction material. Characteristic strength, drying shrinkage, modulus of elasticity, permeability, and resistance to chemical attack are the rigid and time-dependen...

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...
