Aerogel felt is a flexible insulation made of nano silica or metal aerogel as the main material, carbon fibre or ceramic glass fibre cotton, or pre-oxidized fibre felt through a special process, whose characteristics are low thermal conductivity, certain tensile and compressive s...……

Aerogel powder refers to SiO airgel powder products with nanoporous structures.……

Crack generation is more prominent in the summer construction of concrete with a large horizontal surface of concrete. For example, summer construction of cement concrete pavement, cement concrete bridge deck, and bridge deck pavement, etc., have appeared to varying degrees of ea...……

Concrete foaming agent is a type of admixture that helps create stable and uniform foam by reducing the surface tension of a liquid.……

Many problems are often encountered in concrete construction in winter. In the case of low temperature, the internal structure of concrete will also change, and this change leads to the later construction can not be carried out, the material can not meet the construction standard...……

Cement is the main raw material of foam concrete. Because foamed concrete is mostly cured at room temperature and mixed with a large amount of foam, these two points determine its high cement proportion.……

Foam concrete with different strengths shall be constructed in strict accordance with the design requirements. The anti-seepage geomembrane on the top of the foamed concrete subgrade shall be laid under the metal mesh, and the lap joint shall be thermally welded, and the lap widt...……

Before construction, ensure that all kinds of instruments used during construction can operate normally, check their status and break the work, and the materials must be in place.……

In the case of extremely high temperature in summer, it is best to add some retarders in the construction of refractory castables.……

Foamed concrete is a highly entrained sand cement with at least 20% air volume in the cured product.……
