how to calculate 20 mm metal in m 10 mix grade concrete

Overlapping Of Steel Bar | Steel Bar Overlap Formula

Lap length for concrete of 1:2:4 Nominal mix: The Lapping length in tension (MS bar – mild steel bar) along with anchorage value is 58d. Therefore, after deducting the anchorage value, the lap length should be = 58d – 2*9d = 40d. (Here 9d = hook allowance up to 25 mm and k=2) Lap length for M20 concrete:

Thermal conductivity of concrete – A review

 · BA was utilized as a Portland cement replacement in 0%, 10%, 20% and 30% by weight. It was reported that the thermal conductivity increased by adding BA to the mixture due to the increasing unit weight of concrete. The thermal conductivity values were,, and W/m °K for LWC with 0, 10%, 20% and 30% BA respectively.
