Properties of lightweight concrete blocks with waste zeolitic tuff

Abstract

In general, three different types of wall products commonly used in the building sector, namely traditional clay brick, lightweight concrete blocks and aerated concrete, are produced with 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.
