Crushing Strength Test For Ash

The specimen so placed in the compression testing machine is loaded in the rate of 14 N/mm 2 per minute. The crushing load is noted. Then crushing strength is equal to this crushing load divided by the area where the load is applied. At least three specimens must be tested, and the average ought to be taken as crushing strength.

How To Determine The Aggregate Crushing Strength Value …

Procedure for crushing strength of aggregate. Before testing, the aggregate should be in surface dry condition.You can achieve the dry condition of aggregate by placing aggregates in an oven for 4 hours at 100-degree Celcius. The aggregates passing through 12.5mm and retained on 10mm IS sieves are selected for finding aggregate crushing strength.
