Resilient Modulus of Cement-Stabilized Phosphogypsum
Publication: Journal of Materials in Civil Engineering
Volume 8, Issue 1
Abstract
This paper presents the findings of a preliminary study of the dependence of resilient modulus of cement-stabilized phosphogypsum on various material parameters. In particular, the dependence of the resilient modulus on cement content, dry unit weight, moisture content, and curing time was determined. It was found that the resilient modulus increases with increasing density, cement content, and time of curing before testing, but decreases with increasing moisture content. Relationships between resilient modulus and the parameters were estimated and a multiple correlation between the resilient modulus all four parameters mentioned was also derived.
