information that present the geographical distribution of quarry fines, should be compiled to enable the identification of potential end markets. Some of the barriers to utilization are related to the location of quarry fines, the limited awareness of potential markets by aggregate producers, the limited knowledge about quarry dusts arising and their characteristics, and the absence of fully developed fit for use specifications for a wide range of end products. Often quarry fines require some degree of processing before they can be used, which may increase their cost and at the same time requires suitable infrastructure and equipment to become readily available. CHAPTER THREE 3.0METHODOLOGY 3.1 PREPARATION OF MATERIALS The quarry dust was sampled from Kitengela. The parent rock of the dust was established to be granite rock. The lateritic gravel was also sourced from Kitengela. This was obtained at a depth of two meters below the ground surface. The sample was a disturbed sample. Ordinary Portland cement class 32.5 was also used as a stabilizer for comparison purposes. The materials were blended in the following ratios as tabulated. STABILIZED STABILIZER PERCENTAGE OF STABILIZER MATERIAL LATERITIC GRAVEL NONE 0 LATERITIC GRAVEL QUARRY DUST 5 LATERITIC GRAVEL QUARRY DUST 10 LATERITIC GRAVEL QUARRY DUST 15 LATERITIC GRAVEL QUARRY DUST 20 LATERITIC GRAVEL CEMENT 0.5 LATERITIC GRAVEL CEMENT 2.5 The tests described below were all conducted for the tabulated materials.
