CONCRETING METHODOLOGY Cement mortar was cast in 70.6 mm × 70.6 mm × 70.6 mm moulds. Mixing has been carried out at room temperature (27 ± 2 °C).

pozzolana. Saw dust is in abundance in Nige-ria and other parts of the world. Chemical properties of SDA are presented in Table 1, and their comparison with other related ma-terials is presented in Table 2. 3. Materials and Method The materials used were saw-dust ash (SDA), slaked lime, ordinary Portland ce-ment (OPC), sand and water. Saw dust was

There are four batches of sawdust concrete that are concrete containing 0%, 5%, 10% and 15% of sawdust replacing sand by volume. The effect of sawdust content can affect the mixing efficiency and ...

the cement mix increases to 6mm and then to 15 mm at replacement of sand with sawdust. Figure 2: Slump against Sawdust Fraction at 0.65 Water/Cement Ratio The decrease in the workability of the concrete up to 50% sawdust replacement of sand can be attributed to the
