Polycarboxylate superplasticizer polyether macromonomer With the steady development of China's concrete water reducing agent manufacturing industry, especially the introduction of relevant national policies, China's concrete water reducing agent manufacturing industry has ushered in a good development opportunity. At present, China's concrete water reducer products are complete in variety and performance, and the output ranks first in the world. The annual growth rate exceeds 20%, meeting the railways, highways, airports, coal mines, municipal engineering, nuclear power plants and dams in recent years.
Superplasticizers, also known as high range water reducers, are chemical admixtures used where well-dispersed particle suspension is required. These polymers are used as dispersants to avoid particle segregation (gravel, coarse and fine sands), and to improve the flow characteristics (rheology) of s
Domestic most of the original road pavement structure of cement concrete panel, this kind of structure joints and cracks easily, eventually lead to diseases such as fault sets, escapes, pavement damage, and influence the comfort of driving.
Safe and efficient use of polycarboxylate superplasticizer must pay attention to the some problems, like the dosage and the proportion of the materials and avoid to use polycarboxylate superplasticizer with some admixtures, do more research on the polycarboxylate superplastcizer application is a must.
Our country stipulates that the average daily outdoor temperature for 5 days in a row stable below 5 ° C under the conditions of concrete construction, that is, the construction of concrete in winter. Concrete winter construction additives used are: early strength agent, antifreeze agent, water reducer and air entraining agent, can play early strength, frost resistance, procoagulant, water reduction and reduce the role of freezing point. This is an effective method of concrete construction in winter.
