HPC concrete is a new generation of concrete developed at the end of the 20th century and the beginning of the 21st century. It has excellent quality and can meet the needs of various applications. It is worthy of promotion and use. HPC is called High Performance Concrete (HPC) . Under the condition that the concrete meets all the normal properties, it is particularly required to have relatively high performance, including high strength, high workability, high durability, and low permeability, low drying shrinkage, etc. HPC is a kind of concrete for special purposes. The application of HPC can ensure its more safety and more durability. 

SCC (Self-Compacting Concrete) refers to a building material with very good properties of fresh concrete. It can fill the gaps between steel bars and steel bars , and between steel bars and formwork by its own gravity and fluidity characteristics special concrete. SCC has the characteristics of high fluidity and can fill the gaps by itself. SCC has become a new material gradually adopted in building construction and civil engineering. It can solve the problem of floating water, separation, honeycomb, cold joints, floating ash, floating slurry . It is an excellent and good material that can be selected in construction engineering . In fact, SCC is a type of high-performance concrete (HPC), and its requirement is "self-filling, vibration-free tamping" to ensure the compactness and durability of the RC structure. In Taiwan , domestic public engineering (such as MRT , Highway engineering) and private construction industries have also promoted and started to use SCC for many years to solve the above problems, but the process equipment is still traditional concrete batching plant . The traditional production processing  has to be improved, the formation of slurry needs to be improved, and the decline in production capacity , more economical benefits. Our team work has many years of practical experience to develop "Mortar Mixing Gravels " technology which is more suitable for HPC and UHPC concrete production, which can share the ready-mixed concrete industry, in order to supply high-quality concrete and obtain better profits.
