Description: The research presented in this paper focuses on sustainable building practices that promote the use of local, readily available material while implementing low cost building practices. Stabilized and un-stabilized rammed earth reinforced polyvinyl chloride (PVC) columns where tested in axial compression. The load-deflection behaviour was investigated. Based on the results of the test program a recommended design value was determined. Cylinders were also tested to evaluate unconfined rammed earth and provide the characteristics and behaviour under compression loading. Analysis of the data indicated that columns with a 10% cement-stabilized mix provided the highest resistance with an average maximum compressive strength of 3.12 MPa (452.40psi) and an average maximum deflection of 69.37mm (2.73in). The design value for deflection based on the column height of 2.44m (96in) was 4.88mm (0.19in) with a recommended design load of 22.35kN (5018lbs) for these columns. The un-stabilized rammed earth and the 5% cement stabilized columns had a proposed compressive design value of 5.68kN (1,274lbs) and 13.11kN (2,942lbs) respectively. A comparison of the average compressive strength of the cylinders and columns indicated an increase in compressive strength provided by the enclosing of the PVC on average was of 0.73MPa (105.85psi). Based on the research to date, it was concluded that this technique shows potential for building applications.
