The inhibitive action of the ethanol extract of oil from Picralima nitida seeds, towards acid corrosion of zinc, is tested using weight loss, and thermometry methods. It was found that the extract acts as a good corrosion inhibitor for zinc corrosion in 0.1M HCl solution. The inhibitory action of the extract was dis…
This paper studied the influence of water/cement ratio on the flexural strength of concrete made with unwashed local gravel from Abagana in Anambra state. In the research work, concrete beams of dimensions 600mm x 150mm x150mm —three for each experimental point were made. The water/cement ratio, w/c ranged from 0.46 …
This research work set out to develop decaying exponential models for predicting the setting time of concrete as a function of its penetration by proctor needle using common sugar as the admixture. Various percentages of sugar by weight of cement (0.01% —1%) were added to the concrete mix of 1:1:2/0.5 by weight and t…
