What is the bulk density of asphalt vermiculite? Is it better to use asphalt, vermiculite or cement vermiculite when roofing?

Answer:

Cement vermiculite, that is, cement and vermiculite mixed together, construction needs water at the scene, solidification formed after a light insulation material, usually used for roofing or ground insulation. The bulk density of cement vermiculite is about 600-800KG/m3.If only from the bulk density angle, the asphalt vermiculite certainly is better than the cement vermiculite
Vermiculite is a kind of thermal insulation material, even if you do not do roofing waterproof, that after finishing the vermiculite ramming, also must use the cement mortar to make the 2~3CM protection layer. Finished cement mortar protection layer after drying, and then laying asphalt or SBS waterproof coiled material and other waterproof material. Need to say is that asphalt is a waterproof material, cement is a protective layer of thermal insulation material, but also waterproof material of the adhesion layer, and vermiculite is thermal insulation material! Can not be said to be good asphalt, vermiculite, or cement, vermiculite, good drops are a kind of Dongdong Oh!
Asphalt expanded vermiculite products are made of expanded vermiculite and hot asphalt by mixing, pouring, molding and pressing.Asphalt expanded vermiculite products have light weight, heat preservation, heat insulation, sound absorption, hydrophobic and corrosion resistance. Can be used in cold storage projects, industrial pipelines, building roofing insulation materials. The bulk density of asphalt expanded vermiculite products is about 300 ~ 400kg/m3.
