What is Foam Concrete?
Foamed concrete is a new type of energy-saving and environmentally friendly building material that contains a large number of evenly distributed closed pores, is light, heat-resistant, moisture-proof and sound-proof, and is especially suitable for external wall insulation systems of buildings. It can be seen from here that in order to slow down the various properties of foam concrete, its additives must have these properties. Therefore, as the most important raw material of foam concrete, hydroxypropyl methylcellulose is a building material with high water retention, high temperature resistance and strong adhesion.
Why is hydroxypropyl methylcellulose added to foam concrete:
As far as the current production technology is concerned, many closed pores in foam concrete do not exist naturally, but are generated by putting raw materials such as hydroxypropyl methylcellulose into the mixing equipment and mixing them for a long time. This kind of closed pores effectively solves the phenomenon of excessive waste of fillers and saves costs to a large extent. Some people will ask if there is no such effect without adding hydroxypropyl methylcellulose? I can tell you with certainty, yes. Due to the special properties of hydroxypropyl methylcellulose, it can make various raw materials fit together well, so that a special cohesive force can be produced between them, and its tensile and extrusion resistance can be increased.
