Floor heating using foam insulation, such bubbles due to the thickness will be limited to 3 cm, pipe and foam thickness is only 1.5- 2 cm, to this kind of insulating foam material stays high, in addition to carrying the effect of heat insulation, but also
We have made a brief summary of the development of polycarboxylate water reducers in recent years, focusing on the latest research results of different types of polycarboxylate water reducers.With the continuous improvement of technical requirements for e
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
