Abstract

This paper describes the effect of curing periods and bassanite content on strength-deformation characteristics of cement-stabilized soils mixed with bassanite obtained from waste plasterboard, and thus promotes waste plasterboard. The strengths of samples were determined by unconfined compression tests after 1, 3, 7, and 28 days of curing immediately following molding. The effects of curing periods and bassanite content on stress-strain behavior of cement-stabilized soils are quantified. Addition of 20 or 40 % bassanite to the soil increases the shear strength of cement-stabilized soil at short curing periods (1, 3, and 7 days), compared to cement-stabilized soil with no bassanite. This contribution of bassanite at an early stage of curing is significant for improvement of trafficability and the reduction of construction period for soft soil.
