The largest boron reserves in the world are located in Turkey. The production of boron compounds and use of generated boron derivative waste during this production are extremely important for both economically and environmentally. This study evaluates boron derivative waste and investigates doping effects of heat-treated boron derivative wastes on mineralogical, microstructural, and mechanical properties of cement mortar. The waste, portland cement, and wastes heat-treated at temperatures of 400-900 degrees C are characterized. The cement is partially replaced with heat-treated wastes at 800 and 900 degrees C in weight ratios of 15, 25, and 35%. Compression tests are conducted for all mortars and proximate strength value to reference mortar is obtained with the incorporation of waste heat-treated at 800 degrees C by the 25% ratio. From a strength point of view, thermally processed waste is practical for use in the production of cement mortar at 25% by weight.
