CuO is the chemical name for copper oxide. Copper oxide is a black copper oxide with a slightly amphoteric, and slight hygroscopic chemical formula. Its relative molecular mass of 79.545 is 66.36.9g/cm3. It has a melting point of 1026 and a low melti…
Graphene oxide is an oxide formed by the oxidation of graphite by strong acid. It adopts the oxidation reaction of potassium permanganate in concentrated sulfuric acid and graphite powder to obtain a tan edge derivative carboxylic acid base and pheno…
Adding polycarboxylate superplasticizer can make the compressive strength of precast concrete reach 40MPa grade at 8h to 18h.…
With the wide application of polycarboxylate superplasticizer, the requirement of concrete early strength in practical engineering is more and more prominent, so the polycarboxylate superplasticizer has been the focus of research to meet the early st…
