The loss of concrete slump is the result of a combination of factors. Understanding the mechanism of concrete slump loss is helpful to understand the role of polycarboxylate superplasticizer in reducing slump loss.
In order to ensure the construction progress, the construction unit sometimes needs to carry out concrete pouring at a lower temperature.Production is often solved by heating the mixing water.Not only can it ensure the mold temperature of concrete, but al
As the porosity of lightweight concrete is generally up to 50%-70%, and the pore diameter is more than 10 microns, the strength of lightweight concrete is much lower than that of ordinary concrete.As with normal concrete, the strength of the foam concrete
Foamed concrete is foamed by the foaming system of the foaming machine, and the foaming agent is fully foamed mechanically, and the foam and the cement slurry are uniformly mixed, and then casted by the pumping system of the foaming machine, and the natur
The water reducing agent produces a good water reducing effect in the concrete works and has a direct impact on the concrete performance.The surface of the water reducing agent has a good active substance. Under the chemical action of the active material,
High-performance concrete is becoming more and more widely used in current engineering applications, and high-performance water reducing agents are an essential component in the preparation of high-performance concrete.In recent years, polycarboxylate wat
