Should all-lightweight concrete be tested with insulation layer?

All-light concrete needs to be sent for inspection when it is used for insulation layer.

All-lightweight concrete is a kind of concrete made of lightweight aggregate instead of traditional aggregate, which has the advantages of high strength and good seismic performance. When using all-light concrete for building and decoration, there are usually some auxiliary materials, including some insulation materials and insulation layers. The performance and quality of these materials and surface directly affect the use and effect of all-light concrete. Therefore, when using insulation layer in all-light concrete, it is necessary to test the material, thickness, density, thermal conductivity and other related parameters of insulation layer, and judge and evaluate all indicators according to relevant standards and specifications to ensure that the quality of insulation layer meets the standards and requirements stipulated by the state.

In public building projects, such as large supermarkets, hotels, hospitals, cultural venues, etc. The insulation layer used for all-light concrete needs to be submitted for inspection as required, and can only be used after obtaining the corresponding quality certificate.
