ABSTRACT
This chapter determines the effectiveness of using aspiration granite dust (AGD) obtained by crushing granite into crushed stone as filler for dry construction mixtures and mortars based on them. Aspiration systems at crushing and sorting plants and equipment are set to control the dust formed during crushing and to clean the air before it is emitted in the atmosphere. One of the main areas of aspiration dusts possible application is using it as a disperse filler in various purpose dry construction mixtures. Mineral fillers are used to reduce the cement consumption, improve the number of properties of mortars, including those based on dry construction mixtures. The most important task is providing adhesive properties for gluing and masonry mortars. To explain the effect of all investigated additives on the frost resistance of mortars, compressive method was used to determine the volume of entrained air for the characteristic compositions. The chapter explains methodologies for composition design of fine-grained concrete with given workability.
