To investigate the impact of alternative replacement of granite-particles in the production of interlocking tiles. Aggregate mixes of homogeneously mixed raw materials was used for production of experimental interlocking tiles. The mortar method was used for casting purposes. Produced interlocking tiles were cured and treated for twenty-eight days before the physical and mechanical tests were conducted. For improved mechanical strength, an optimum mix of granite particles to lateritic soil to silica sand of 2:1:1 is recommended for suitable replacement for granite particles in the production of interlocking tiles. A simple model that relates the granite particles/cement ratio to water/cement ratio for interlocking tiles was determined, with a coefficient of correlation and standard error of estimate of 0.85 and 0.65 respectively. The investigation had shown that cheaper and easily available raw materials, such as lateritic soil and silica sand may be used as suitable replacement for granite particles in the production of interlocking tiles with acceptable properties. Developed model that relates the granite particles/cement ratio to water/cement ratio for interlocking tiles would be very useful for control studies or production purposes. © 2012 Kavala Institute of Technology.
