Basalt Boulders, 8 14 inches diameter Specific Gravity (Apparent) = Soundness test (Sodium Sulphate, % Loss) = Compressive Strength = 13,810 psi

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: 2060 Mpa, which denotes that depending on the mineral makeup, basalt rocks fall in the strong .

The optimum compressive strength was obtained with 1% basalt fiber content. Increase in the content of basalt fiber increased splitting tensile strength and flexural strengh for both treated and untreated recycled concrete aggregate . Use of untreated recycled concrete aggregate reduced compressive,splitting tensile and flexural strength of concrete.

 The percentage increase of split tensile strength of basalt fiber concrete mix compared with 28 days compressive strength of Plain Concrete is observed as 62% .  The flexural strength of basalt fiber concrete is also found have a maximum increase of 54% at 4kg/m3 of fiber content.

Keywords: Basalt, Regression analysis, Point load strength index, Uniaxial compressive strength Introduction Uniaxial compressive strength (UCS) is an important property of rock. Uniaxial compressive strength is widely used in the slope stability analysis and in .

compressive strength of basalt rock . is concluded that the highest concentrated stress of surrounding rock is lower than the approved compressive strength of basalt rock mass in the worst condition,the incl...

Feb 17, 2016· The compressive strength of concrete increases with increasing basalt fibre content up to %: after this, the concrete compressive strength tends to decrease gradually by 12%. This is due to the cohesive decrease between the cement paste and the aggregate that plays a significant role in the compressive strength of concrete.

SSRG International Journal of Civil Engineering (SSRGIJCE) – volume 2 Issue 4 April 2015 ISSN: 2348 – 8352 Page 38 gravity and lower in absorption and abrasion loss values. Based on this comparison, it is clearly obvious that basalt is likely to be suitable for use in .

The basalt is classified according to Walker's classification system based on petrology and texture of the rock and is divided into the following three different petrographic types (Walker, 1959): Olivine Tholeiite basalt, Olivine basalt, Porphyritic basalt. Table 1 gives a number of rock engineering

the uniaxial compressive strength (UCS), and to propose appropriate Is50 to UCS conversion factors for different coal measure rocks. The rock strength determined by the PLT, like the load frame strengths that they estimate, are an indication of intact rock strength and not necessarily the strength of the rock mass. THE UNIAXIAL COMPRESSIVE STRENGTH TEST
