Hi,
I hope someone can enlighten me on what is the reason for ASTM to change the limit of heat of hydration value on Table 4 from 255kJ/kg @ 3days to 335kJ/kg @ 3days? This is a huge increase on the limit making the common type 1 cement compliant to type 2-MH as well. Will this change leads to a higher risk of early stage concrete cracking?
