PROPERTIES OF DENIZLI VOLCANICS AND POTENTIAL USING FOR CONCRETE PRODUCTION
Abstract
In this study, mineralogical, petrographical and chemical properties of volcanic rocks (Denizli Volcanics) with basaltic trachyandesite composition which are located in southern of Denizli province have been investigated. Their physical and mechanical tests have been carried out on the samples to find out their performance both as an aggregate in concrete and as building stone in the construction sector. Unit weights, water absorption, porosity and uniaxial compressive strength of the tested samples are between 2250-2960 kg/m3, % 0.06-0.4, % 0.15-10.22 and 52.4-170.2 MPa, respectively. Average 28-day compressive strengths of the concrete are 94.44 MPa and the results fit the mineralogical and petrographical characteristics. There is a total of 2750 million ton probable reserve and it is an alternative aggregate to limestone which has already been produced in the region. High strength concrete production is vital for high quality construction especially in earthquake zones.
