dc.description.abstract |
Quality controlling of aggregates is a major concern in aggregate industry. Cost
of quality controlling can be minimized via finding correlations between different test on
aggregates and rocks. Los Angeles abrasion value test, Aggregate impact value test,
Uni-axial compressive strength test, Point load index and Schmidt hammer rebound
value test were performed on a total of 22 gneissic metamorphic rock samples, which
were collected from selected two quarries in Meepe and Nebada areas of Sri Lanka to
investigate correlations between these test parameters. Correlations were developed
between each parameter to reduce the cost of quality controlling by means of regression
analysis. The study found a strong correlation between Loss Angeles abrasion value test
and Aggregate impact value test. By analysing correlation between tests, mineralogy and
rock properties validity of this correlation can be proved for common application |
