Impact of Suitable Replacement of Granite - Particles on Interlocking Tiles

Abstract

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.

Modeling and Simulation of Mechanical Properties of Pulverized Cow Bone and Lateritic Paving Tiles

“…The increasing population of the world has propelled both private and public organizations to constantly embark on infrastructural development, a scenario that has encouraged the use of building accessories and products such as paving tiles. It is therefore imperative to constantly explore sustainable materials to develop some of the infrastructural products that would guarantee a sustainable environment [1].…”

“…Paving tiles are usually of different shapes and sizes; they range from square, rectangle, star shape etc. The standard thicknesses are usually 60 mm with common dimensions of 60 x 30, 40 x 40, and 30 x 30 cm [5][6]. In Nigeria, the conventional materials used in the production of paving tiles are granite, silica sand, and cement as a binder.…”

“…Several works have been conducted on the use of readily available and affordable materials in the manufacturing of paving tiles. Ohijeagbon et al [1] used laterite as a partial replacement of granite in the production of interlocking tiles due to the availability of laterite. Ajao and Ohijeagbon [8] successfully utilized corncobs, an agro-waste and charcoal to produce paving tiles, but the sustainability of corncobs waste presents a limitation due to the seasonal availability of agricultural wastes.…”
