Read MoreIt is of great important that the compression strength of concrete is known in construction. The types of aggregate used in the concrete have great effect on the compression strength of the concrete. This paper looked into the compression strength of basalt fiber reinforced concrete when it bears expanded clay as aggregate and when it bears the usual gravel as aggregate.
Read MoreProperties obtained from compression tests included unconfined compressive strength, Youngs Modulus, axial strain at failure or at 50 of ultimate load, failure type, and failure plane angle to horizontal. The results indicate that there appears to be two different layers of rock
Read MoreNov 01, 2020 For basalt rocks, Malik et al. 12 investigated Deccan basalt rock and found the dynamic compressive strength between about 170 MPa and 260 MPa at a strain rate of about 400s to 1600s. Lindholm et al. 13 found a much lower dynamic strength of about 110 MPa to 125 MPa at a strain rate of about 600s and 1100s for Dresser basalt rock.
Read MoreRock mass strength is defined by three parameters including unconfined compressive strength of intact basalt and two others related to the degree of fracturing of the material. Experimental results for elevated temperature extend the applicability of these parameters to the near surface environment of

Some construction materials such as weak rock may lose strength due to weathering within the design life of the embankment. These long-term effects shall be considered when selecting properties to use for design. 5 .4. Methods of Determining Soil and Rock Properties
Read MoreRock hardness property is usually measured to determine the compressive fracture strength, to determine whether a rock is a soft rock or a hard rock. T. The rock hardness of basalt is 6 as per the Mohs scale and can be observed through a combination of its compressive strength. Generally, 100-300 Mpa or Megapascal is the compressive strength.
