The hybrid aluminium matrix composites were developed using the stir casting method. Several samples of the composites consisting of AA6061 alloy with 3, 6, 9, 12 and 15% by wt. each of CCSp and SiCp with average particle sizes of 38μm and 42.3nm for SiC, and 63μm and 50.01nm for CCSp were produced and characterized for strength. The microstructures of the developed composite materials revealed uniform distribution of reinforcement particles in the base matrix and excellent bonding between the base matrix and reinforcements after casting. The results obtained showed that addition of CCSp and SiCp reinforcement to the alloy increased the tensile strength and hardness. Also, a mathematical model was proposed for predictive tensile strength of nano-composite and validated by comparison with results of the physical experiment and those of other authors. The proposed model is in excellent agreement with experimental data. The nano-particulates reinforced composite presented maximum improvement in ultimate tensile strength value (53.4% and 8.5% of that for the unreinforced matrix and micro-composite respectively) at reinforcement level of 15wt.% nSiC/nCCS.","PeriodicalId":159399,"journal":{"name":"International Journal of Mechanical and Civil Engineering","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131349344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, proper calibrations as per optimal mix proportions of these aggregates to give blocks that meet minimum requirements by various standards are lacking. In this study, a mix ratio of 1:8 (cement: aggregates) and a water-cement ratio of 0.5 was adopted at different percentages of laterite replacing sand. Block sizes of 450 x 225 x 150mm were used. Curing was done for 3, 7, 14, and 28 days. A total of 104 blocks were prepared and tested for density, compressive strength, static modulus, water absorption and thermal conductivity. Results showed a decrease in density, compressive strength and thermal conductivity values with the addition of laterite. On the other hand, the water absorption of sandcrete-laterite blocks increased, as the blocks became more permeable. The decrease in thermal conductivity indicates better insulating properties of the Sandcrete-Laterite Blocks. These blocks will, therefore, reduce the energy requirements in a building. The study recommends an optimal replacement level of 10% of sand with laterite which gave a strength of 1.87N/mm2 and is 6.9% greater than the minimum requirement of 1.75N/mm2 by the Nigerian Building Code for individual blocks.","PeriodicalId":159399,"journal":{"name":"International Journal of Mechanical and Civil Engineering","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133575559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
