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 С20/25...С60/75. 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.

Jens Jensen was one of America's greatest landscape designers and conservationists. Using native plants and "fitting" designs, he introduced the influential Prairie Style of landscape architecture. He championed the preservation of natural landscapes such as the Indiana Dunes (now a national lakeshore), the State Park System in Illinois, and numerous parks in Wisconsin. When he died in 1951 at the age of 90, the New York Times called him the "dean of American landscape architecture." Now that environmental issues have recaptured public attention, Jensen's visionary work and remarkable career are being rediscovered by a new generation of admirers.
