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.…
Other five kinds of water-reducing agents: sulfamate high-efficient water reducer, fatty acids high-efficient water reducer, HSB aliphatic superplasticizer, powder polycarboxylate, casein will be introduced.…
Melamine water reducing agent is the product of the reaction that melamine is first sulfonated by sulfuric acid and then condensed with formaldehyde, so the chemical name is sulfonated melamine-formaldehyde resin, which belongs to the anionic surfact…
Naphthalene Sulfonate Water Reducing Agent is the product of naphthalene sulfonated by sulfuric acid and then condensed with formaldehyde, which belongs to an anionic surfactant.…
Concrete superplasticizer is high efficienct water reducing agent. Its difference from ordinary water reducing agent lies in the high-water reduction rate. The water reduction rate of ordinary water reducing agent is generally 5%-10%, and the water r…
Plant meat is a product made from plant raw materials such as soybeans and peas, adding some substances to imitate the taste and flavor of meat.…
Importantly, Boron has the potential to induce cardiomyocyte cell cycle entry and potentially cardiac tissue regeneration after injury. Boron might be beneficial as a supplement in MI and may be a good candidate substance for the anti-fibrosis approa...…
Apart from improving the field emission efficiency by optimizing the aspect ratio (length/diameter) of 1D nanostructures, other methods were also used to enhance the field emission current. Wang and Li found that laser irradiation could effectively i...…
