Different water reducing agents have certain effects on the strength and late strength of the hardened cement paste.The high-efficiency water reducing agent can effectively reduce the mixing water consumption of the concrete mixture, and has a significant
On the question of how to add a water reducing agent, the problem worth noting is that its dosage should be scientifically controlled.Condensate will use different types of cement, and the same type of water reducer will have different types.
With the continuous evolution of human civilization, the scientific and technological knowledge is becoming more and more perfect, and the pace of electronic, informational, technical, and industrialization is striding forward. The city's high-rise buildi
Generally, the grouting method is adopted to repair the integrity cracks of building the structure. This method mainly USES pressure equipment to pour some cementing materials into concrete cracks.
Polycarboxylate superplasticizer is a newly developed type with a "flowing" structural feature. After being added to the concrete, the mixing degree of the mixture in the concrete can be enhanced, and a certain amount of fly ash can be added to the mixtur
The polycarboxylate water-reducing agent is a graft copolymer having a comb-like molecular structure, the main chain is an alkyl carbon chain having a carboxyl functional group, and the side chain is a polyoxyethylene (and/or polyoxypropylene) structural
