Abstract

Due to the importance of the use of pozzolans in this study, we attempted to better understand the available pozzolans in Khash region. Therefore, two different rocks from Khash region were investigated for quality assessment. These two rocks are dacite and basaltic and after mill they are called dacite and basaltic ash. In this study, two different types of concrete were designed using inorganic polymer made from the mentioned ash and their mechanical properties were investigated, which significantly showed that the basaltic ash had higher compressive strength, so that the highest compressive strength was obtained from samples made with 72 MPascal basaltic ash. However, the highest compressive strength obtained from specimens made with dacite ash is 49 MPascal. Scanning electron microscopy also showed that many particles were not reacted in samples made with dacite ash. Also, mercury injection porosity test showed that samples made with dacite ash had more porosity than basaltic samples.
