## What's the permissible compressive strength of concrete

Answer (1 of 2): PERMISSIBLE STRESSES (CLAUSE B2, IS456:2000) The working stress method is based upon the concept of permissible stresses Permissible stresses are obtained by dividing the ultimate strength of concrete or yield strength of steel (02% proof stress) by appropriate factors of safNov 13, 2017· Permissible stresses are obtained by dividing the ultimate strength of concrete or yield strength of steel (02% proof stress) by appropriate factors of safety The factors of safety used in working stress method are: (i) For concrete (a) in bending compression – 30 (b) in direct compression – 40 (ii) For steel – 178PERMISSIBLE STRESSES (CLAUSE B2, IS456:2000)

## IS 516 (1959): Method of Tests for Strength of Concrete

IS:5161959 Indian Standard METHODS OF TESTS FOR STRENGTH OF CONCRETE o FOREWORD 01 This Indian Standard was adopted by the Indian Standards Institution on 10 November 1959, after the draft finalized by the Cement and Concrete Sectional Committee had been approved by the Building Division Council 02 Testing plays an important role inJul 07, 2016· Compressive strength as per American Codes In case of American codes, compression strength is defined in terms of cylinder strength fc’ Here compressive strength of concrete at 28 days curing is obtained from a standard cylindrical specimen 150mm diameter and 300mm high loaded longitudinally to failure under uniaxial compression pressive Strength of Concrete & Concrete Cubes |

## What Is The Characteristic Strength Of Concrete? [Civil

The characteristic strength of concrete is the result of the compressive strength of the concrete cube test The design strength is the required strength of concrete to be designed as per the IS code For example, assume that the strength of concrete required M25, and the target design strength is 285 N/SqmmSection 3 of BS EN gives principles and rules for normal and highstrength concrete (15–105MPa cube strength) and for normalweight concrete Lightweight aggregate concrete (< 2200kg/m3) is covered in section 11 of the Code and is not covered in this publicationProperties of Concrete sefindia
