I have a residential-concrete specification that calls for a 124 concrete mix. What does that mean A. This is a little-used method for showing the amount of cement sand and coarse aggregate in the concrete. The specification should also say if those proportions are by weight or volume
In the nominal mix concretes the constituents of concrete are measured by volume and the proportions are pre- determine such as 1816 148 136 and 124 etc. The unit of measurement of cement is a bag of 50 kg having a volume of 0.035 cum
