Abstract
29Nov 2017 AN OPTIMUM EVALUATION OF FOUR DIFFERENT NIGERIAN PORTLAND CEMENTS FOR HIGHWAY RIGID PAVEMENTS. Isaac Akiije. Department of Civil and Environmental Engineering, Faculty of Engineering, University of Lagos, Akoka, Yaba, Lagos, Nigeria.
Highlights
This study investigated the trend of four different types of new brands
Each brand of fresh concrete produced based upon the cement type was subjected to slump and compaction factor tests
Four newly produced brands of cements that are made in Nigeria were employed whilst optimizing same for the purpose of highway pavement design and construction independently
Summary
Rt. It involved using nominal maximum size of 19 mm granite as coarse aggregate in the individual concrete production. The four different types of cement were individually subjected to tests that included specific gravity, fineness, consistency, setting time, chemical and metallic compositions. According to ASTM C33 (2016) and AASHTO M 6 (2013) aggregates are classified by standard specification for concrete production as fine and coarse.
