A compressive testing machine having capable of applying 40 tonnes.The rate of loading is 4 tonnes per minute. 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.
However the case of curing using Paint material gave values of compressive strength higher than the other curing methods, in all cases and at all ages, except in the case of () recycled aggregate which provided the maximum value of the compressive strength in the case of curing with water as shown in Fig. 3, Fig. 4, Fig. 5 and Table 2.
May 09, 2019· The crushing strength or aggregate crushing value of a given road aggregate is found out as per IS-2386 Part- 4. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement aggregate possessing low aggregate crushing value should be preferred.
In very high-strength concrete mixtures (greater than 70 MPa) the crushing strength of the aggregate can be a limiting factor to the ultimate compressive strength. In lean concretes (with a high water-cement ratio) the crushing strength of the aggregates is not so significant.
