So care should be taken while calculating the amount of Cement Sand and Aggregate required for 1 Cubic meter of Concrete Method 1 DLBD method to determine material requirement for 1 Cum concrete The DLBD Dry Loose Bulk Densities method is an accurate method to calculate cement sand and aggregate for a given nominal mix concrete 1 part cement 2 parts sand and 3 parts gravel This concrete mix proportions is perfect for making ponds elevated plant boxes and similar projects because this particular mix of concrete produces a water tight end product that allows only a limited amount of water to seep through
