“…Table 1.0 show the Classification of Lightweight Concrete. Source: ASTM C 330 and C 332-09 (2007) Several researches have been carried out on the utilization of alternatives material as aggregate in concrete production; Ramezanianpour et al (2009) and Ndoke (2006) assessed the performance of palm kernel shells as a partial replacement for coarse aggregate in asphalt concrete, while Falade (1992) explored the appropriateness of palm kernel shells as aggregates in light and dense concrete for structural and non-structural purposes. Nimityongskul and Daladar (1995) examined the utilization of coconut husk ash, corn cob ash and peanut shell ash as cement replacement in concrete production.…”

ABSTRACT:The properties of lightweight concrete, such as aggregate impact value, aggregate crushing value and compressive strength were assessed utilizing periwinkle shell (PWS) as partial replacement for coarse aggregate. Standard mix of 1:2:4 with varying percentages of 0%, 10%, 20%, 30%, 40%, 50% and 100% partial replacement of PWS using water/cement (W/C) ratio of 0.55 was used. Seventy two cubes of 150 mm x 150 mm x 150 mm were casted; allowed to set for 24 hours before remolding, and were properly cured. The strength characteristics of each cube were evaluated using Compressive Testing machine at the curing ages of 7, 14, 21 and 28 days. The ACV and AIV obtained are 31.59% and 22.61% respectively which is within the acceptable limit. An optimum compressive strength value of 16.79 N/mm 2 and 16.71 N/mm 2 was obtained with the addition 20% and 30% partial replacement of coarse aggregate with PWS in 28 days. These values are within 15-25 N/mm 2 and it is suitable for Lightweight concrete. The research demonstrates that the utilization of PWS in structural/insulating lightweight concrete, at lower volume of replacement, will reduce the utilization of granite in concrete. Thus, decreasing the production cost of concrete and the ecological contamination brought about by the dumping of periwinkle shell. © JASEM http://dx.doi.org/10.4314/jasem.v20i3.2

Right diaphragmatic eventration simulating neonatal pleural effusion: a case report

Abstract: This is a report of a 10-day-old term female infant with right diaphragmatic eventration in whom the initial diagnosis was right pleural effusion with probable ipsilateral lung hypoplasia. The diagnostic pitfalls in such a case and suggestions of how to avoid them are discussed.
