Comparative Analysis of Sandcrete Hollow Blocks and Laterite Interlocking Blocks as Walling Elements
This study considered the production and testing of sandcrete hollow blocks and lateriteinterlocking blocks with a view to comparing their physical characteristics and productioncost. Some units of sandcrete hollow blocks and laterite interlocking blocks were made usingmachine vibrated sandcrete block mould and hydraulic interlocking block making machinerespectively. The blocks were tested to determine their density and compressive strength. Theresults obtained from the tests were compared with the specifications of Nigerian Buildingand Road Research Institute (2006), Nigerian Building Code (2006), and Nigerian IndustrialStandards (2000). The results indicated that the compressive strength of 225mm and 150mmsandcrete hollow blocks varies from 1.59 N/mm2 to 4.25 N/mm2 and 1.48N/mm2 to3.35N/mm2 respectively, as the curing age increases from 7 to 28 days. For lateriteinterlocking blocks, the strength varies from 1.70N/mm2 at 7 days to 5.03N/mm2 at 28 days.All the blocks produced satisfied the minimum requirements in terms of compressive strength,by all available codes. The cost per square metre of 225mm and 150mm sandcrete hollowblocks are ₦2,808:00 and ₦2,340:00 respectively, while that of laterite interlocking blocks is₦2,121:20.It was concluded that laterite interlocking blocks have better strength and arecheaper than sandcrete hollow blocks.
