Abstract

This research project is an experimental investigation of the effect of low levels of macroporosity on the engineering properties of materials, specifically elastic modulus and unconfined compressive strength. This project will contribute to several years of research at Montana Tech involving the study of materials containing large voids, and will specifically address macroporosities of ~1.3% - 2.8%. The laboratory testing was carried out using cylindrical plaster and hydrocal specimens, nominally 3 inches in diameter and 5.5 inches in length, with one to two one inch diameter centered spherical styrofoam inclusions. Twenty four plaster samples including six solids, six single inclusions (~1.4% porosity), and twelve double inclusions (~2.8% porosity) were tested. Twelve hydrocal samples including four solids, three single inclusions, and six double inclusions were tested. This paper aims to evaluate the correlations between macroporosity and the corresponding elastic modulus and unconfined compressive strength, and compare the results with those of the previous large voids research that has been done at Montana Tech.
