polycarboxylate superplasticizer for ready mixed concrete

Type of water reducing agent The types of water reducing agents are lignosulfonate, naphthalene water reducing agent, melamine water reducing agent, polycarboxylate water reducing agent, casein water reducing agent, sulfamate water reducing agent, acrylic water reducing agent and so on. Lignosulfonate: It is an ordinary water reducing agent, its raw material is lignin, generally extracted from conifers, lignin is polymerized by three kinds of lignin monomer, coniferol, coniferol, sinapol, used in mortar can improve the construction, fluidity, improve strength, water reduction rate in 5% -10%. Naphthalene sulfonate superplasticizer: is the earliest use of high efficiency superplasticizer in China, is the product of naphthalene through sulfuric acid sulfonation, and then condensation with formaldehyde, belongs to anionic surfactant. The appearance of this type of water reducer depending on the product can be light yellow to dark brown powder, easily soluble in water, and has a good dispe…
