LABORATORY EVALUATION OF VOLCANIC ASH IN PORTLAND CEMENT CONCRETE

A laboratory test program was undertaken to determine the effects of volcanic ash as a substitute for Portland cement concrete. Concrete mixtures with zero, 10, 15, 20 and 25 percent replacement of volcanic ash were evaluated in the study by compressive strength determination, air-void system analysis and rapid freeze-thaw durability testing. The results of the study indicate that volcanic ash can be utilized as a partial replacement of Portland cement in concrete to produce strong, durable concrete. However, replacement of more than 10% volcanic ash for Portland cement resulted in a very non-durable concrete. (FHWA)
