The US Commerce Secretary has announced that the US will temporarily lift tariffs imposed on Ukraine during the Trump administration to help Ukraine recover its economy and continue to show support for the Russia-Ukraine situation. "For steel mills t…
As an admixture, superplasticizer is added to concrete to reduce water consumption and increase the strength of concrete. At present, the high-performance water-reducing agents used in concrete engineering are mainly polycarboxylic acid superplastici…
Concrete is a mixture of a graded aggregate, sand, water, and cement. It is necessary to study the influence of concrete components on the effect of the high-efficient superplasticizer in order to give full play to their due effect.…
Boron nitride powder is a pure white ceramic material with a hexagonal crystal structure similar to graphite. It is a product with high temperature resistance, corrosion resistance, high insulation and good lubricity.…
GH4049 is a nickel-based superalloy, which is an age-hardening alloy. The corresponding grade is GH49. Its nickel content is about 70%.…
Using concrete additives is the most effective, economical, and simple technical way to reduce the cement dosage, improve the utilization rate of industrial waste residue, and realize the high durability and performance improvement of concrete.…
Researchers at Chalmers University of Technology in Sweden have proposed that a new type of graphene could be used as a special effect material for the production of high-performance electrodes for sodium batteries.…
The foaming agent for cement form a foam with a certain tension and then mixing the foam and cement slurry at the same time. During the mixing process, the cement will continue to expand. When the expansion effect reaches the preset ratio, foamed cem…
