Abstract

Timber Industry Ash (TIA) and ordinary Portland cement (OPC) were evaluated for its ability to increase the pH of an acidic meta-sedimentary residual soil. The residual soil samples were obtained from within the campus of Universiti Kebangsaan Malaysia (UKM), Bangi. The average initial soil pH is 4.75. The results showed (1) a trend of increasing pH over time, (2) a trend of increasing pH with increasing water content (decreasing pH over weight to volume dilution ratio), and (3) a general trend of increasing pH with the increase of the amount of ash, cement and mixture of ash and cement. The data also showed that the best results in increasing soil pH values to between 9.5 and 11.0 were a mixture of 20% to 75% TIA in a soil-TIA mix or 1% to 2% cement in a soil-cement mix. The results also illustrated the importance of specifying the duration of pH measurements, and the weight to volume ratio of samples to facilitate comparisons with other researchers' data.
