· The test techniques specified include the 10% Fines Aggregate Crushing Value (10%FACT) which is a wet and dry crushing test, the Durability Mill Index (Sampson and Netterberg 1989 ), which is a wet abrasion and impact test and a water soaking disintegration test.
Get PriceAs per IS 456, the individual compressive value of a concrete cube should not be less than 75% of its grade. Example – If the concrete grade is M20, then the individual crushing value should not be less than 15 N/Sqmm. The individual crushing value difference between the cube should not be greater than 15%. Hope you enjoyed the topic.

Get PriceThe test that is performed to measure the relative resistance is called the aggregate crushing value test. Impact value test – A relative measure of the resistance of aggregate due to the sudden shock or impact on it is called aggregate impact value. Abrasion test – The abrasion test is conducted to find the toughness of aggregate material.
Get Pricethe aggregate crushing value should not exceed 45% for aggregate used for concrete other than for wearing surfaces, and 30 % for concrete for wearing surfaces, such as runways, roads for pavements. aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, as an alternative to crushing .

Dry theme in an oven for 4 hours at a temperature of 100 °C to 110 °C and then cool at room temperature. Fill the aggregates up to about 1/3 full in the cylindrical measure and tamp for 25 times with rounded end of the tamping rod.
Get PriceThe aggregate shall be taken as in the case of crushing strength value test, the aggregate should pass through mm sieve and retained on 10 mm sieve. It should be oven dried at 100°C to 110°C for four hours and then air cooled before test.
Get PriceCrusher Product Gradation Charts Aggregates required for a given job are generally specified by a full set of gradation limits and other relevant properties of the material. When rock is crushed, the product includes material of the size of the crusher setting, some slightly larger and the rest of the material smaller than the crusher setting.
Get PriceIn mixes with slag aggregate, there are increases in compressive and indirect tensile strength in mixes with 2% cement content.
