Aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the test aggregates are subjected to a specified load under standardized conditions and the strength of the aggregate used in road construction is expressed by numerical index ... As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.
The strength of concrete is generally measured by testing concrete cubes which are prepared from the concrete used in that particular construction The cube strength of concrete is specifi ed by a structural engineer and is assessed by crushing concrete cubes at a specifi ed age 28 days after castingFurther Details
30 Mpa This is a high strength concrete and is suitable for suspended structural beams precast beams and flagstones heavyduty workshop floors and suspended reinforced floors To make 1 cubic metre of 30 Mpa concrete you will need to mix 10 bags of cement with 065 cubic metres of sand and 065 cubic metres of stoneFurther Details

American Concrete Institute Code Cement Concrete Terminology–ACI 116R00 Standard Practice for selecting proportions for normal heavy weight and mask concrete–ACI 2111 91 Reapproved 1997 Guide for selecting proportions for High Strength concrete with portland Cement and Flyash–ACI 2114R93 Reapproved 1998Further Details
Minimum three specimens should be tested at each selected age If the strength of any specimen varies by more than 15 percent of average strength the results of such specimens should be rejected The average of three specimens gives the crushing strength of concrete The strength requirements of concrete Calculations of Compressive StrengthFurther Details
Strength of hardened concrete measured by the compression test The compression strength of concrete is a measure of the concretes ability to resist loads which tend to compress it The compressive strength is measured by crushing cylindrical concrete specimens in compression testing machine The compressive strength of concrete is calculated by the failure loadFurther Details
Highstrength concrete is specified where reduced weight is important or where architectural considerations call for small support elements By carrying loads more efficiently than normalstrength concrete highstrength concrete also reduces the total amount of material placed and lowers the overall cost of the structureFurther Details
