The book presents the technology of rational use of non-metallic natural resources and industrial waste with the possibility of using aggregates in the composition of heavy concrete. This technology will contribute to the rational use of natural resources, which will recycle accumulated over the years in the dumps, which will have a positive impact on the cost of products, and also considers the production technology for mining and transporting raw materials for the production of cement, given methods of laying concrete mixture and the duration of vibration when placing the concrete.

The book presents the technology of rational use of non-metallic natural resources and industrial waste with the possibility of using aggregates in the composition of heavy concrete. This technology will contribute to the rational use of natural resources, which will recycle accumulated over the years in the dumps, which will have a positive impact on the cost of products, and also considers the production technology for mining and transporting raw materials for the production of cement, given methods of laying concrete mixture and the duration of vibration when placing the concrete. Determination of the causes of overspending of cement and how to save cement - by chemical additives and the use of high-quality forms for test samples. Reducing consumption of cement in the separate technology of preparation of concrete mixture. Storage and transportation of cement. Considered ways of heating concrete in the manufacture of precast concrete and monolithic structures. The method of steam-heating provides the most favorable heat-moisture conditions for accelerated concrete hardening. This method is used mainly on sites where there is an excess of steam with a lack of free electric resources.
