The feldspar grinding process is the most important of the mill production line, so we must pay attention to the choice of the equipment.
normalweight sand a wide range of concrete densities may be obtained Aggregates for structural lightweight concrete usually have a top size of minus 34 in or minus 12 in Most lightweight concretes use a lightweight coarse aggregate 34 in to 4 mesh 12 8 with ordinary sand minus 4 mesh minus 48 mm however other combinations of

The basic design for lightweight concrete is covered in Eurocode 2 Part 11 with section 11 having particular rules required for lightweight aggregate concretes Concrete is considered to be lightweight is the density is not more than 2200kgm 3 the density of normal weight concrete is assumed to be between 2300kgm 3 and 2400kgm 3 and a
Lightweight concrete mixture is made with a lightweight coarse aggregate and sometimes a portion or entire fine aggregates may be lightweight instead of normal aggregates Structural lightweight concrete has an inplace density unit weight on the order of 90 to 115 lb ft³ 1440 to 1840 kgm³ Normal weight concrete a density in the range
specifications for structural lightweight concrete do not typically have a requirement for maximum watertocementitious materials wcm ratio The wcm ratio of structural lightweight concrete cannot be precisely determined because of the difficulty in determining the absorption of lightweight aggregate
