USAGE OF AKSARAY IGNIMBRITES AS NATURAL LIGHWEIGHT AGGREGATE AND EVALUATION OF THE PRODUCTION FOR LIGHTWEIGHTHOLLOW MASONRY UNITS

Solid and/or hollow masonry wall elements on the form in construction sector is the main component of the basic elements of the wall. nowadays light weight form of masonry wall elements are commonly used as construction industry. taspinar region and around aksaray ignimbrite volcanic formations in the form of mass shows a very wide spread areas. these ignimbrite formations in the high proportions of pumice grains are also included. as is known, the production of ignimbrite rocks in the world and our country are considered elements of masonry block wall. therefore in this study, eligibility criteria of ignimbrite formation for en standards related to lightweight aggregate have been analyzed and the evaluation of their usability for obtaining a light form-cavity wall blocks have been investigate in detail.
