Abstract
This study examined the weathering characteristics of laterized concrete with laterite-granite fine ratio as a factor. This was done with a view of ascertaining the suitability of laterite and granite fine as substitutes to the conventional fine aggregate (sand) used in the construction industry. The weathering characteristics was examined by conditioning laterized concrete cubes to varying temperatures and alternate wetting and drying, which all represent the operating weather conditions (wet and dry seasons) in the tropics, including Nigeria. The mix proportion used was 1:2:4, the curing age of the laterized concrete was based on 28-day curing age, while the Avery Denilson Testing Machine was used in determining the compressive strength of the treated laterized concrete cubes. The result of this research showed that the compressive strength of laterized concrete with laterite-granite fine ratio variation decreases when subjected to alternate wetting and drying. It was also discovered that a laterized concrete with a laterite-granite fine ratio of between 40 and 60% conditioned to a temperature range of 75-125°C attained compressive strengths as high as 22.52 Nmm 2.
