  • Effect of Concrete Strength and Slab Thickness on Floor
    Effect of Concrete Strength and Slab Thickness on Floor

    Mar 01, 2001 The load-carrying capacity of a floor varies as the square of the floor thickness. You can estimate the expected change in floor load-carrying capacity due to reducing the thickness from 6 inches to 5.62 inches instead of 6 inches as follows: (5.62/6) squared = 0.88. Thus the reduction in thickness causes a 12 percent reduction in load-carrying

    Crushing strength of concrete rings with a polyurea

    Jul 01, 2020 The concrete rings of this type lost their load-carrying capacity as soon as the concrete cracked in the tension areas of the shell. These components cracked already at very small straining. When the maximum load was reached, the cracks virtually did not develop, and the components broke up into four smaller pieces ( Fig. 13 , Fig. 14 )

    How to Calculate the Load Bearing of Concrete

    Knowing the load-bearing capacity of your concrete is essential to make sure that what you plan to have supported by the wall or slab will not be too heavy and cause it to crack and break. While cracks in a slab may not seem like a big deal, the smallest crack represents a large amount of downward pressure that may be crushing pipework beneath
