Production of Biodiesel from Waste Ube Fruit Oil Using Acid-Base Catalysis

Vol/Issue: Volume 1, Issue 2  •  Pages: 1-10  •  Published: 30 Nov 2016

A two step process consisting of esterification and transesterification was developed to produce biodiesel from crude waste ube fruit oil. The oil was extracted from the waste ube pulp using solvent extraction process. The free fatty acids (FFA) in the oil were converted to methyl esters in the pre-esterification ste…

DECAYING EXPONENTIAL MODELS FOR PREDICTING THE SETTING TIME OF CONCRETE AS A FUNCTION OF ITS PENETRATION BY PROCTOR NEEDLE USING SUGAR AS ADMIXTURE

Vol/Issue: Volume 1, Issue 1  •  Pages: 1-8  •  Published: 29 Feb 2016

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…
