The AIV is the percentage of fines produced from the aggregate after subjecting it to a standard amount of impact. Below 10 would be regarded as strong, above 35 would normally be regarded as too weak to be used in road surfaces.

Syenite is also an igneous rock which is hard and durable like granite. The structure of syenite is coarse-grained and its crushing strength varies from 90 to 150 MPa. It is available in different colors but typically they are light in color. Uses. Crushed syenite is commonly used as aggregate in pavement construction and concrete making.
marble aggregate crushing value Construction aggregate Wikipedia Construction aggregate, or simply aggregate , is a broad category of coarse particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates.
Sep 01, 2020 Consistent with the smaller crushing value of aggregates, their compressive strength was greater because the compressive strength of sandstone, basalt, and marble aggregate concrete mainly depended on the strength of mortar and the strength of the interface between mortar and aggregate although the crushing value of marble was lower than that ...
Dec 09, 2013 marble rock aggregate falls below the minimum value given above by 29. The higher the bulk density, the lower is the void content to be filled by sand and cement 38. The results obtained from the research indicate that metamorphic rock marble aggregate is less densely packed.

Oct 12, 2015 Aggregate crushing value ACV and aggregate impact value AIV are two well-known British tests for assessing the degradation of aggregate. ... The tests were carried out on 20 types of crushed aggregate produced from limestone, marble and granite. All tests were conducted on the samples with natural moisture content as well as saturated samples.
The aggregates crushing value gives a relative measure of resistance of an aggregate to crushing under gradually applied compressive load. The aggregate crushing strength value is a useful factor to know the behavior of aggregates when subjected to compressive loads.

Jul 20, 2018 Bending strength test. This test is compulsory for knowing about the power of the stone in bending. There are three common types of tests done for the same purpose. Modulus of rupture test application of the load at a mid-point. ASTM C99 test and ASTM C120 Slate test application of the load at a mid-point.
5.1 This test has been widely used as an indicator of the relative quality or competence of various sources of aggregate having similar mineral compositions. The results do not automatically permit valid comparisons to be made between sources distinctly different in origin, composition, or structure.
Crushing Limestone to produce fine aggregate results in the generation of a substantial amount of fine sizes minus 0.075mm or 200 mesh commonly referred to as dust. These fines do not aid in the production of good quality concrete and therefore must be removed from the sand before combining with Coarse Aggregate and cement.
