Size Of Aggregate For Cement Block Making

Size Of Aggregate For Cement Block Making FOB Reference Price: Get Latest Price Along with the urgency of capital construction in cities, the aggregate demands for cement block machine are increasing fast so as to produce more and more cement blocks in Sri Lanka Larger aggregate diameters reduce the quantity of cement and water needed because of its lower Voids When the aggregate is sieved through 475mm sieve, the aggregate retained is called coarse aggregate Gravel, cobble and boulders come under this category The maximum size aggregate Different Types Sizes of Aggregate for Concrete For a given cement – aggregate ratio, block strengths theoretically should increase with an increase in the top size of the aggregate provided the aggregate is well graded and mix can be thoroughly consolidated in the machine Almost all concrete block producers today use aggregate smaller than ½ inch although scattered reports have GRADATION OF AGGREGATE FOR CONCRETE BLOCK
