  • Dynamic compressive properties of Kalgoorlie basalt rock

    01.11.2020· 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 400/s to 1600/s. Lindholm et al. 13 found a much lower dynamic strength of about 110 MPa to 125 MPa at a strain rate of about 600/s and 1100/s for Dresser basalt rock.

  • Assessing the uniaxial compressive strength and tangent

    Basalt was used as an ornamental stone in any historic and ancient cities in Jordan. Measuring the uniaxial compressive strength (UCS) and the tangent Young’s modulus (Et) in the laboratory requires premium quality specimens with special core dimensions. This research focuses on correlations both UCS and Et with Leeb Rebound Hardness Test (LRH).

    Key Words: basalt fibre, high strength concrete,durability, Spilt tensile,compressive, flexural strength. I: INTRODUCTION The use and definition of high-strength concrete (HSC) has seen a gradual and continuous development over many years. In the 1950s, concrete with a compressive strength of 5000 psi (34 MPa) was considered high strength. In the 1960s, concrete with compressive strengths of

    01.01.2020· The compressive strength of a material is to resist compressive loads which the material is being pushed together. The Compressive strength of basalt fibre reinforcement in the aluminium matrix alloy for 0 to 2.5 wt% gained an increased value of about 11.98% and up to 10 wt% reinforcement higher value of 41.66% was obtained. The increase in compressive strength is due to the presence of hard basalt fibre reinforcement which imparts high strength
