uniaxial compressive strength from the results of the point load test. 4. Test Results and Discussion 4.1 Uniaxial Compressive Strength Test Results The mean values of uniaxial compressive strength of the tested rocks are listed in Table 2. The strength values range from a low of 9.16 MPa for Marl to a high of 101.08 MPa for

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 ...

Chapter 2 Design for Shear - Engineering

The compressive strut capacity of concrete is reached if Vn/(bwd) = 10.0√fc’. Additional stirrups cannot increase section shear strength, as the concrete strength is considered exhausted when Vn/(bwd) > 10√fc’. Design aid SHEAR 2 consists of 3 tables that may …

compressive strength up to about 1200 oF. Lightweight concrete has insulating properties, and transmits heat at a slower rate than normal weight concrete with the same thickness, and therefore generally provides increased fire resistance. Figure 2 shows the effect of high temperature on the modulus of elasticity of concrete. The

COMPRESSIVE STRENGTH TESTING THE CUBE CONFUSION

Compressive strength testing using 2” x 2” (50mm x 50mm) cubes is specified on many structural grouting projects, high strength topping projects, structural vertical/overhead repair projects and DOT projects in the industry today. Cube testing is also the most popular way of advertising compressive strength on technical data sheets.
