FIELD: construction.
SUBSTANCE: invention can be used in construction, nature management, and in particular in the field of waste processing. Method of production of building materials includes mixing waste of calcareous limestone sawing, cement and water, dosing the mixture into a mold and pressing. In this case, before mixing, the sawing waste of limestone-shell rock is classified by size. For mixing use small to 5 mm and larger than 5 mm fraction waste. Portland cement is used as cement. Mixing of the components of the mixture is carried out in a concrete mixer in a ratio of 1:7:0.5, respectively. Before dosing the mixture into the mold, the resulting solution is fed from the concrete mixer to the main proprietress bunker. Vibropressing is carried out, followed by pushing the molded article onto the pallet, aging of molded articles on pallets at a temperature of 20 °C and relative air humidity of 90–95 % for 12–14 hours. After 24 hours, the products are transported to the warehouse of the finished product to form stacks.
EFFECT: technical result is to increase the strength, durability, thermal insulation of building materials.
