The present study examined wear characteristics of A356/melon shell ash particulate composites. Dry-sliding the stainless steel ball against specimen disc revealed the abrasive wear behavior of the composites under loads of 2 and 5N. The composite showed lower wear rate of 2.182 × 10-4 mm3/Nm at 20 wt% reinforced material under load of 5N. Results showed that wear rate decreased significantly w...

Median third eye was found to develop from transplanted pineal gland of external gill stage tadpoles in the recipient 5 toe stage tadpoles of Bufo melanostictus. Pineal gland along with a bit part of brain tissue of the donor external gill stage tadpole was cut out and transplanted into a pit made between two lateral eyes of 5 toe stage recipient tadpoles. Half of the operated tadpoles were tre...

the present study was carried out to investigate the effects of different levels of canola meal eithr with or without phytase addition on laying hen's performance. a number of 288 layer hens (the strains of hy-line w36) at the 60th week of age, selected as based on the same egg production percentage and body weight were, assigned to a factorial arrangement with a completely randomized desi...

In studies conducted to determine the workability of concrete, the bagasse ash and rice husk ash were added as a partial replacement for cement. Trial mixes with the varying water cement ratio, replacement percentage, quantity of super plasticizer and viscosity modifying agent, were prepared and tested. The results were used as the basis for defining three optimum cement replacement mix proport...

Fly ash is a waste produced mostly from the burning of coal in thermal power stations, which contributes to environmental pollution. Also, a number of studies have been conducted to investigate the influence of randomly oriented fibers on the engineering behavior of coarse grained and fine grained soils. The influence of randomly oriented polypropylene fibers on the engineering behavior of soil...

This study investigates the feasibility of co-firing fly ashes from different boilers, circulating fluidized beds (CFB) or stokers as a sustainable material in alkali activators for ground granulated blast-furnace slag (GGBS). The mixture ratio of GGBS and co-firing fly ashes is 1:1 by weight. The results indicate that only CF fly ash of CFB boilers can effectively stimulate the potential chara...

The coal utilization in thermal power plants in Malaysia has increased significantly which produces an enormous amount of coal combustion by-product (CCBP) or coal ash and poses severe disposal problem. As each coal ash is distinct, this study presents the geochemistry of the coal ash, in particular fly ash, produced from the combustion of local coal from Kuching Sarawak, Malaysia. The geochemi...

P. Priyadharshini, G. Mohan Ganesh, A.S. Santhi Abstract— The reduction in moisture of fresh concrete results in plastic shrinkage due to tensile stress induced by capillary pressure. When the tensile strength signs beyond the capacity of concrete, it cracks and this effect in early stage of concrete is termed as plastic shrinkage of concrete. This becomes a serious issue for large surface area...
