Calculating the Load Bearing Capacity of Concrete Floors

Re: Calculating the Load Bearing Capacity of Concrete Floors 12/04/2009 7:28 AM There isn't any one formula, the selection of which one depends on how the slab is supported, where the rebar is placed, the type and placement of loads, etc. etc.

Compressive Strength of Concrete Hollow Blocks (Formula

Nov 15, 2017 · This is the ultimate failure strength of the block, not the usually quoted compressive strength. The compressive strength that is used for design purposes and specified in catalogs or standards will only be a fraction of this.

High-Strength Concrete

High-strength concrete is typically recognized as concrete with a 28-day cylinder compressive strength greater than 6000 psi or 42 Mpa. More generally, concrete with a uniaxial compressive strength greater than that typically obtained in a given geographical region is considered high-strength, although the preceding values are widely recognized.

Concrete Compressive Strength

Compressive strength Facts for Kids

When the limit of compressive strength is reached, materials are crushed. Concrete can be made to have high compressive strength, e.g. many concrete structures have compressive strengths in excess of 50 MPa, whereas a material such as soft sandstone may have a compressive strength as low as 5 or 10 MPa. Introduction

Understanding Minimum Specified Compressive Strength ( f c
