Testing of Building Stones Rock Tests on Lab Field

Jun 14, 2016· The approximate values for ordinary stone are: Granite 10 – MPa; limestone – 20 MPa and sandstones in the range 4 – 15 MPa. 4. Impact test. For toughness; A steel hammer of 20 N is allowed to fall axially in the specimen. The blow at which the specimen breaks represents the toughness of the stone. 5. Fire resistance test

7 Lab Test on Aggregate Should Satisfy for Use in Concrete

Place the mould in the aggregate impact testing machine and administer 15 numbers of blows of a metal hammer. After that, remove the crushed aggregate and sieve it through a mm sieve. The aggregate impact value is measured as % of aggregates passing through the sieve (W2) to the total weight of the sample (W1).

Impact Test on Aggregates GharPedia

Aggregate impact value (The value of aggregate impact test) = (W1/W2)*100. The value of aggregate impact test should not be more than 45% by weight of aggregates, used for concrete other than wearing surface. An impact value 35% is permissible for the bituminous macadam. Maximum permissible impact value for the water bound macadam is 40%.

Effects of Aggregate Properties on Concrete Size, Grading

Effects of aggregate properties on Concrete like Grading of aggregates depends on the proportions of coarse and fine aggregate. If grading of aggregate is varied, it also changes cement paste content (cost economy), workability of the mix, density and porosity. It is an important factor and has a maximum influence on workability.
