Abstract
Aggregates, or granular materials, are currently one of the most sought-after construction materials. Natural aggregate deposits are quite common in the world, but their widespread consumption and progressive environmental degradation forces many countries to take measures to reduce the depletion of natural resources. One of the solutions is the use of alternative aggregates. The use of this type of aggregates enables further minimization of the volume of wastes and their adverse impact on the environment and the neutralisation of the remaining waste by, among others, production of artificial aggregates. Forecasts for the future assume a reduction in the production of artificial aggregates, brought about by the production of alternative aggregates from recycling. Many research centres around the world conduct research on the assessment of the effect of various aggregates on the properties of concrete and mortar. This article compares selected properties, i.e. the flexural and compressive strength and bulk density of epoxy mortars, in which the natural aggregate has been partially replaced by perlite, expanded clay and rubber waste pellets. The type of filler used differentiates the mortar characteristics recorded. The tested properties of composites indicate the possibility of their use in construction industry.
