Properties of Concrete - Memphis

Concrete compressive strength depends upon many factors: quality and proportions of the ingredients the curing environment. Stress–Strain Diagram 12 4 8 Strain Concrete Material Properties Most structural concrete have f’c values in the 3,000 to 5,000 psi range. High-rise buildings sometimes utilize concrete of 12,000 or 15,000 psi

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

Timber as a structural material - an introduction

Strength issues Timber has a very high strength-to-weight ratio. This is illustrated as a comparison between steel and timber in Figure 6. Commercial considerations When compared to other structural materials, softwood timber has a low density (Table 2). This means it can off er lightweight structural solutions
