7 LAB TESTS ON AGGREGATE TO CHECK QUALITY FOR
The crushed aggregate is allowed to pass through 2.36 mm IS sieve. And the impact value is measured as percentage of aggregates passing sieve (W2) to the total weight of the sample (W1). Aggregate impact value = (W1/W2)*100. Aggregates to be used for wearing course, the impact value shouldn’t exceed 30Concrete Cube Testing, Cube Molds - Humboldt Mfg,Concrete Cube Mold, Steel. Single-cavity steel cube mold with base plate is 6 x 6 x 6" (152 x 152 x 152mm). H-2827MHD Concrete Cube Mold, Steel, Heavy-Duty. Single-cavity, two-part, steel cube mold with base plate. Used for compression testing of concrete cubes. H-2827MP Concrete Cube Mold, Plastic. Plastic metric cube mold, single-cavity.In concrete compression test, normally 150mm x150mm,Diffrent types Conrete Cube moulds may be used, 100x100x100, 150x150x150, 250x250x250 & 300x300x300. It depends upon the size of aggregates, for 20mm agg. 100mm / 150 mm cube mould are used. For 40 mm over size moulds are used.
