Rock mass strength is defined by three parameters including unconfined compressive strength of intact basalt and two others related to the degree of fracturing of
3.5.2 Concrete. Concrete is a widely used construction material, consisting of Portland cement, water, sand, gravel, crushed stone, and other materials such as expanded slag.
The table here gives the compressive strength of different stones obtained from rocks in Newton per mm square. Rock. Stone. Range of Crushing Strength
Abstract— In this paper studied the properties of the basalt stone to fusibility of the basalt stone tile. Tests on basalt available in Kerli Tal: Panahala Dist.: Kolhapur of
The more compact grained and heavier a stone the harder it is. Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 30
Hence, stones possessing high crushing strength and silica presence in addition to hardness are preferable. Granite and Basalt can be used. Stone building near sea shore. 3. Heavy
The crushing strength for a good building stone should be higher than 100 N /mm 2. Crushing strength values of some of the stones are as given here. Rock:

Stress strain relationships of concretes and rocks under instantaneous stress: a) w/c = 0.70 b) w/c = 0.58 c) w/c = 0.45 d) w/c = 0.28 * Due to the high strength of the basalt rock and the high compressive strain in the granite rock at peak stress, the curves for these rocks are shortened; the values of compressive strength (peak stress fc
The strength of the stone improves if this moisture is removed before The compressive strength of basalt varies from 200 to The specific gravity varies from 2.5 to 3.0 and crushing

The rock hardness of basalt is 6 on the Mohs scale, and can be seen through a combination of its compressive strength: 100300 Mpa (Megapascal), its tensile strength: 1030 Mpa, and its shear strength: 20
The more compact grained and heavier a stone the harder it is. Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 3040%. Being dry stones allow more crushing strength than when wet. It is the ability of a stone to endure and maintain its essential and distinctive characteristics i.e. resistance to
The sand stone may show a very low crushing strength when loaded parallel to bedding planes than when loaded perpendicular to the same structure. Except for sandstone, quartzite and most other sedimentary Bulk density values in gram/cubic cm for some common building stones are granite2.7, basalt2.9, sandstone2.6, and limestone

Basalt sand making process. 1 Sand making: The crushed basalt (≤40mm) is conveyed to sand making machine through the belt conveyor for fine crushing and shaping, to obtain basalt sand. 2 Sand washing: If the impurity content of basalt is relatively high, or the sand is strictly required, a sand washing machine can be used to clean the
Limestone: It can be used as raw material for sand and aggregate production and the stone powder can also be collected. Basalt: mixed in the concrete, sand made of basalt can reduce the weight of the concrete, but not reduce the strength, and has the characteristics of sound insulation and heat insulation, which is a good aggregate for

Based on the results obtained, the impact of aggregate crushing resistance on the mechanical properties of HPC was assessed. To this end, three properties were analyzed: modulus of elasticity; splitting tensile strength and compressive strength of HPCs in dependency on aggregate crushing resistance (Fig. 5, Fig. 6, Fig. 7).Download :
Considering the lack of highquality stone materials in some highway’s construction areas of China, coupled with the high cost of procurement and transportation, the road engineering cost is more and more expensive. The strength of syenite was the lowest, and the strength of basalt was the highest. The early compressive strength of
Table 1 shows the crushing strength of various stones. Due to the nonuniformity of the material, usually, a factor of safety of 10 is used to find the permissible stress in a stone. Basalt: 153 to 189: Granite: 104 to 140: Slate: 70 to 210: Marble: 72: Sand Stone: 65: Lime Stone: 55: Laterite: 1.8 to 3.2: Table 1. Crushing Strength of
A higher compressive strength between1,800 psi (12.45 MPa) and 19,000 psi (131 MPa) means the stone can endure an upper crushing load. Dry or wet conditions as per load determine the compressive strength of the
Table 1.1 shows the crushing strength of various stones. Due to nonuniformity of the material, usually a factor of safety of 10 is used to find the permissible stress in a stone. Hence even laterite can be used safely for a single storey building, because in such structures expected load can hardly give a stress of 0.15 N/mm2.
The produced concrete mixtures in this research work were prepared using Portland cement type I (OPC) with 3.15 g/cm3 specific gravity and 371 m 2 /kg surface area following the ASTM C150 (Ghahfarokhi et al., 2014) along with a watercement ratio (w/c) of 0.37.Also, micro silica sand with an average particle size of 200 μm and 2.65 specific gravity was
