Concrete and Mortar Production using Stone Siftings

NOTE EDITORE

The monograph analyses the state of the art (problem) in using stone siftings and aspiration dust obtained in natural stone crushing for producing concrete aggregates and fillers for dry construction mixtures and mortars on their basis. The influence of disperse fraction in stone siftings and aspiration dust on structural, mechanical and rheological properties of cement composite construction materials is investigated. Hypothesis for obtaining technological conditions, providing positive effect of the disperse fraction on strength and other properties of cement based concrete and mortar is proposed. Experimental results on studying properties of dry mixtures and mortars on their basis using stone crushing aspiration dust as filler are presented. Efficiency of using fillers, based on igneous rocks, on adhesive and other properties of mortars is demonstrated. Methodology for design of mortars composition for given mortar properties in case, when aspiration dust is used as filler, is proposed. The monograph presents experimental results on fine-grained concrete including as a main filler stone siftings with up to 20% of disperse fraction. It is shown that it is possible to produce fine grain concrete class ?20/25…?60/75. Technological parameters of vibro-pressed fine-grained concrete with raw stone siftings are developed. Methodologies for composition design of fine-grained concrete with given workability are proposed. Possibility for producing macroporous light-weight concrete for walls and filtration materials, based on stone siftings fillers is shown.
