The fire resistance of concrete masonry walls depends on the geometry of the concrete masonry units, and the density of the concrete block. inversely proportional to the compressive strength and the bulk density of the concrete hollow block. 12-14. Concrete masonry Hollow light weight blocks are manufactured with the lowest concrete density of 1100 Kg/m3 density and the block density at 963 Kg/m3 to 688 Kg/m3. Building Materials 8.

Filters. In general, Hollow Block is a Type of Concrete Block Used for building internal and external walls. 400x250x200. At Emcon, Hollow lightweight blocks are available with a face dimensions of 400 x 200 mm (L x H) and 390 x 190, with varying thickness of 100, 150, 200, 250 and 300 mm. Category. 8 items.

The blocks are available in a standard face size of 440 x 215mm and in thicknesses of 140mm and 215mm in … They are manufactured to BS EN 771-3 using Class 1 limestone aggregates. Hollow concrete block saves time in building walls due to its large dimensions.Due to the load-carrying capacıty, the Hollow Block is playing an important role in the construction industry. 750-875 For a given unit configuration, the fire resistance of a concrete masonry wall increases as the concrete density decreases.
