density of sand is higher than the density of sawdust, therefore as sand is replaced by an equal volume of sawdust the mass of the mixture reduced, leading to a decrease in density. An equation of ρ=0.0239x2-0.6.4806x+2330.9 with an R2value of 0.9866 may be used to represent the variation of the 28-day density of concrete (ρ) with sawdust ...
