In general, three different types of wall products commonly used in the building sector, namely traditional clay brick, lightweight concrete blocks and aerated concrete, contain pumice and perlite. We have created alternative block walls with Bayburt stone (BS) containing zeolite, namely lightweight concrete masonry blocks (LCMBs). BS was an aggregate, cement dosages ranging from 150 to 250 kg/m3 were a binder, 3 different type of superplasticizers were selected as a chemical additive. Compressive strength, water absorption, unit weight, elevated heat effect, freeze-thaw resistance, capillary water absorption and thermal conductivity tests were performed. Compressive strength and freeze-thaw resistance of LCMBs are higher than the respective values for the other traditional wall products - with less amount of cement usage. Compressive strength values of lightweight concretes (LCs) were between 4 MPa and 9 MPa on the 3rd day, unit weights of the LCs were between 1.43 and 1.60 kg/dm3, thermal conductivity values of the so produced block wall elements were ≈ 0.55 W/mK.
