What about the 3 Gorges Dam? From old times to the present, concrete has played an important duty in the human building and construction of houses and significant projects. This synthetic blend made from natural materials such as limestone and clay i…
A new high-performance polycarboxylate superplasticizer with a high slump retention type is available. Made of isopentenyl, polyoxyethylene ether, and small monomer via free radical polymerization it can make a significant difference in water reducti…
HPEG is most commonly used for the production superplasticizer products of polycarboxylic Acid. HPEG2400 1. Scope of HPEG2400 1. HPEG is most commonly used for the manufacturing of superplasticizer polycarboxylic acid products. 1. Mix the oil direc…
A new type of superplasticizer polyoxyethylene-ether macromonomer is known as concrete water reduction. This superplasticizer uses polyoxyethylene-ether macromonomer as well as unsaturated and sulfonic acids group monomers by radical polymerization.…
Polycarboxylate superplasticizer is the third generation of high performance superplasticizer after common superplasticizer and superplasticizer.…
Because the steric hindrance of the extended polymer side chain effectively hinders the secondary agglomeration between cement particles, so the product has high dispersion performance and can maintain this performance for a long time to realize the…
Common superplasticizers include lignosulfonates and their derivatives, advanced polyols and polyol complexes, hydroxy carboxylic acids and their salts, polyvinyl ethers and their derivatives, etc.…
Polycarboxylate superplasticizer has more advantages than traditional naphthalene and aliphatic superplasticizer in mixing high strength grade concrete, but its advantages of high water reduction cannot be brought into full play when the strength is…
In order to improve the early strength of concrete, some manufacturers will add triethanolamine, calcium chloride and industrial salt to the superplasticizer, especially in winter or prefabricated component factories and cement products factories tha…
The wide application of mineral admixtures mainly derived from industrial solid wastes diversifies the composition of cementitious materials, which is one of the main characteristics of modern concrete.…
Adding polycarboxylate superplasticizer can make the compressive strength of precast concrete reach 40MPa grade at 8h to 18h.…
The impermeability of concrete is related to its porosity and pore structure.…
The World Platinum Investment Association (WPIC) said recently that carmakers are accelerating reductions in palladium use and increased use of platinum due to concerns about Russian palladium supplies. However, it still expects a significant surplus…
Tantalum carbid is a white metal-like cubic cubic crystalline product that falls under the category of sodium chloride. Tantalum carbide has been used in the past to stop cemented carbide-sintered grain growth.Particle Size: -325mes Tantalum-Carbid…
Following the progress in Russia-Ukraine peace talks, the gold price fell more than 1% the next day, hitting its lowest in a month, and palladium prices briefly tumbled by nearly 9%."We have seen metal prices going into free fall when the Russia-Ukra…
