Compared with UPV values in Table 3, the PKS concrete produced for all the mix proportions and w/c ratios of, and is good while the ones for w/c ratio of and are fairly good. This implies that PKS concrete at lower w/c ratios has low workability but high strength, which is adequate for structural works.
