Objective Question & Answer

QUESTION

Objective Question

Q.1

Flexure strength of concrete is determined as:

कंक्रीट की आनमन सामर्थ्य (Flexural Strength) किसके द्वारा निर्धारित की जाती है?
A
Modulus of rigidity

दृढ़ता मापांक

B
Modulus of rupture

विभंग मापांक

C
Modulus of plasticity

प्लास्टिकता मापांक

D
Modulus of elasticity

प्रत्यास्थता मापांक

Answer ( Option B)

Modulus of rupture

विभंग मापांक

Solution

The flexural strength of concrete is expressed in terms of the Modulus of Rupture. It

represent the maximum tensile stress developed at the extreme tension fibre of concrete at

bending failure.

कंक्रीट की आनमन सामर्थ्य को विभंग मापांक (Modulus of Rupture) के रूप में व्यक्त किया जाता है। यह

bending failure के समय कंक्रीट के बाहरी तनन फाइबर पर उत्पन्न अधिकतम तनन प्रतिबल होता है।

According to IS 456:2000, the estimated flexural strength of concrete is:

IS 456:2000 के अनुसार कंक्रीट की अनुमानित आनमन सामर्थ्य का सूत्र है:

Where

fcr = Flexural strength or Modulus of Rupture / आनमन सामर्थ्य या विभंग मापांक

fck = Characteristic compressive strength of concrete / कंक्रीट की अभिलाक्षणिक संपीड़न सामर्थ्य

Hence, the flexural strength of concrete is determined in terms of the Modulus of Rupture.

अतः कंक्रीट की आनमन सामर्थ्य को विभंग मापांक (Modulus of Rupture) के रूप में निर्धारित किया जाता है।
