Download Solution PDFअवधारणा:
लक्ष्य औसत सामर्थ्य (fm) = fck + 1.65δ
जहाँ δ = मानक विचलन
| कंक्रीट का ग्रेड | मानक विचलन (δ) |
| M10 - M15 | 3.5 |
| M20 - M25 | 4.0 |
| M30 - M50 | 5.0 |
गणना:
दिया गया है
ग्रेड M20
M20 गेड कंक्रीट की अभिलक्षणिक संपीड़न सामर्थ्य (fck) = 20 MPa
M20 ग्रेड कंक्रीट की लक्ष्य औसत सामर्थ्य (fm) = 20 + 1.65 × 4
M20 ग्रेड कंक्रीट की लक्ष्य औसत सामर्थ्य (fm) = 26.6 N/mm2
