| What are the characteristics of natural stone? Fire resistance of various stone are different, some stone under high temperature, the occurrence of chemical decomposition.waterproof roof panels b.c. patio covers
Granite: at 600 C due to composition of mineral heating uneven and split. Expansion and contraction of stone is also thermal expansion and contraction, but if the heat after cooling, the contraction can not return to the original volume, and will retain a part of a permanent expansion.composite decking for sale in florida
if the rock can not resist the power of such expansion, there will be damage. Generally, if the water absorption is less than 0.5%, the frost resistance is not considered. Compressive strength The compressive strength of the stone may vary depending on the mineral composition, the thickness of the crystal, the uniformity of the cemented material, the area of ??the load, the load and the angle of the cleavage.houses with red roofs in the philippines
If the other conditions are the same, the crystalline particles are usually compact and bonded together with each other, with a higher strength. Dense volcanic rocks in the dry and saturated water, the compressive strength is no difference (water absorption is very low), if it is porous and water-bearing cement, its dry and wet strength, there are significant differences.moisture protection for timber floor joists
