In the preparation of underwater self-compacting concrete (SCC), it is required to have both high fluidity and strength. Compared with ordinary concrete which is of low tensile strength and poor toughness, SCC has an even lower water/binder...
The construction industry is an area where silica fume has the earliest research and is mostly used and applied. A reasonable dosage rate of silica fume, which must be determined through tests, can improve various properties of mortar and c...
Steel fiber reinforced concrete is a fast-developing composite material with short steel fibers distributed in random directions. As shown in the table below, a 2% steel fiber dosage is enough to improve various properties of concrete. Stee...
Material reference of steel fiber reinforced concrete Steel fiber: The mechanical properties of the selected steel fibers should not be lower than the requirements of first-grade carbon steel, and its geometric parameters should meet the re...
Gasoline is a mixture of various hydrocarbons, of which the light components are highly volatile. In the process of gasoline storage and transferring, a part of the light components will volatilize and be discharged out. Vapor recovery is i...
Composite Hose Handling Guide The operation personnel must be trained before handling a standardized and safe operation of composite hoses. Before use The following should be checked before each use of the composite hose: Whether the surfac...
What is reactive powder concrete (RPC) Reactive powder concrete (RPC), as a type of ultra-high-performance concrete (UHPC), is a cement-based composite material with high compressive strength, high durability, high toughness, low porosity. ...
Corrosion prevention with high performance concrete (HPC) Embedded steel and other metals of reinforced concrete in coastal and marine areas are subject to corrosive environments where the presence of chloride ions, as well as oxygen is one...
High rebound percentages of shotcrete will not only cause a great waste of raw materials, increase the construction cost and working time, but also lead to a construction site with high dust content, which seriously affects the health and s...
Epoxy resins are thermosetting polymers containing epoxy groups. As they have characteristics such as excellent mechanical properties, processing properties, corrosion resistance, low price, they are widely used as adhesives, structural mat...
