Difference Between Tensile and Compressive Stress Pediaa.Com

If it is a tensile (stretching) force, the material experiences a tensile stress. If it is a compressive (squeezing) force, the material experiences a compressive stress. The main difference between tensile and compressive stress is that tensile stress results in

Curing Techniques for Improving the Compressive Strength

Similarly, more time may be needed for curing when concrete or ambient temperatures are lower. Typically, 20 degrees Celsius (68F) is considered an ideal curing temperature. moisture of in-situ concrete are therefore important for proper hydration so that concrete can gain sufficient compressive strength. Curing directly influences the
