the cement mix increases to 6mm and then to 15 mm at replacement of sand with sawdust. Figure 2: Slump against Sawdust Fraction at Water/Cement Ratio The decrease in the workability of the concrete up to 50% sawdust replacement of sand can be attributed to the
cement amounts can be reduced because concrete strength is directly related to the water/cement ratio. Definition of Mineral Admixtures Mineral admixtures include fly ash, hydrated lime, silica fume and ground blast furnace slag. Many of these materials have cementlike properties, augmenting the strength and density of the finished concrete.
