Coincident with the investigation of the utilization of Mount Pinatubo ejecta on the production of paving blocks for sidewalks, parking areas and other footpaths, a study on the durability of the blocks was also undertaken. Blocks with a plan area of 1OOmm x 200mm and a thickness of 85mm were prepared with three mixture proportions. The mixture proportions were prepared to represent three strength levels. Specimens from each mixture were subjected to both natural and accelerated weathering conditions. The compressive strength in accordance with ASTM C 936 and the abrasion resistance in accordance with ASTM C 779 were determined for various ages. The test results as shown in this paper for the durability parameters selected, show favorable long term properties of the paving blocks.
