ENGINEERING CHARACTERISTICS OF VOLCANIC ROCK AGGREGATES OF RWANDA

Applicability of the volcanic rock aggregates in the construction industry are still in the stage of exploration of finding best building materials. Usage of volcanic rock as an aggregate could prove one global identity of Rwanda in Infrastructure engineering as the place has abundance of rich volcanic rocks especially in the north-western part. This paper investigates the engineering behavior of volcanic rock aggregates with respect to performance standards e.g. compressive strength, point load test, and permeability analysis. Tested on International Standards of ASTM D4630-96(2008) and UNIEN 1926:2006, the outcome of the study is compared with one of the recent work on similar direction [19] to find volcanic rock aggregates from Rwanda could be suitably use in construction industry.
