Aggregate Crushing Strength Test Machine
Recycling of Concrete (Recycling Coarse Aggregate)
Crushing value test: The crushing value test was carried out by compression testing machine (CTM). The total load of 40 tones was applied at the rate of 4 ton per minute. The percentage crushing value was determined by divided the passing weight from total weight of aggregate. Slump Test: The Unsupported fresh concrete, flows to the sides and a sinking in height takes place. This vertical ...
