Kruskal-Wallis Test as Analytical Tool for Key Components of a Newly Developed Core Mixture
Journal Title: Leonardo Electronic Journal of Practices and Technologies - Year 2011, Vol 10, Issue 18
Abstract
The use of Kruskal-Wallis test as an analytical tool for the key components of a newly developed core mixture was studied. The study showed that Kruskal-Wallis test can be use to analyze a core mixture using data collected on the properties of the core mixture. In this work the data used was the dry compression strength of cores produced using the core mixture. The key components of the core mixture; the binders and the sands were analyzed. The result showed that the dry compression strength values of the core mixture depend on the type of sand and on the nature of the binder used. This analysis agreed with previous works carried out by several other authors using conventional methods for analysis of core mixtures.
