Compressive strength of stone for various stones
compressive strength: It is defined as the ratio of load by its cross-sectional area at which it fails. Mathematically, compressive strength (P)= load/cross-sectional area in N/mm2. The compression strength of the stone is carried out to determine the compressive strength of the stone. To perform this test take 6 test blocks of The values of compressive strength and split tensile strength are found by pa rtial replacement of cement in the mixture with varying percentage of 0%, 10%, 20%, 30% and 40% by wei ght of cementANALYSIS OF USE OF BASALT AGGREGATE IN CONCRETE MIXES WITH GRANITE

Diyarbakır and Karacadağ mountain basalt, found locally in deposits as thick as 150 m cover an area of 10,000 km 2 in Southeast Anatolia, Turkey and occur approximately a half meter below the soil cover or as a surface cover. The creeping basalt flow from It doesn’t bruise, which allows us to perform more aggressive carving techniques. In terms of resistance, granite has a compressive strength of 19,000 psi and a tensile strength of 4.8 MPa (700 psi). Granite is heavy but lighter than marble.

Types of stones used in the construction Basalt, Granite,
1) Basalt and Trap: Basalt is an igneous rock, formed by the solidification of molten magma under pressure. Basalt has a medium to fine-grained structure. These stones are basically used as road metals. It has a specific gravity of 1.8-2.9 and a compressive strength of 200-350 N/mm2. Basalt is mostly in dark grey to black in colour.According to the test results, there is no significant difference between the strength parameters measured in water-saturated and in freeze–thaw subjected conditions.

Effect of Aggregate Type on Properties of Ultra-High-Strength
Basalt is a magma effusive rock with a content of 45–52% SiO 2, which has a compressive strength of 150–300 MPa and a tensile strength of 10–20 MPa. Experimental investigations on the use of basalt aggregate in high-strength concrete mixes, which were conducted by Kishore et al. and presented in [ 20 ], indicate its influence on Compaction strength. After a threshold region the rock begins to show ductile deformation under confining pressure. The pressure under which a rock deforms is known as its compaction strength.

The propagation of the shear wave/blast wave causes a minimum effect in the dolomite and quartzite tunnel hence proved to be the This paper is focused on the influence of the geological nature and quality of the aggregates on the compressive strength of concrete and explains why it is important not to ignore the characteristics of aggregates in the estimation of the strength of concrete, even for virgin aggregates.
