Strength performance comparison of mortars made with waste fine aggregate and ceramic fume

This paper presents results of the research programme focused on utilising multiple waste materials in production of cement mortars. Waste sand of natural origin was harnessed as aggregate. Ceramic waste fume obtained as a by-product during manufacturing of coarse “post demolition” aggregate was used to partially replace binder in mortar mixtures. Properties of both fresh mixes and hardened mortars were tested and analysed. Such properties as: consistency of fresh mix, density, compressive strength and flexural strength of hardened composites prove that mortars in question can be used to fabricate elements characterized by less demanding mechanical characteristics.
