SUBSTANCE: method to manufacture concrete and reinforced concrete products, solid structures and facilities from concrete mix consists in the fact in a mixer for 1.5-3 minutes they mix sand, cement and crushed stone with water and electrolyte. The produced mix is poured into a curb, a cassette or a form, working surfaces of which are electrodes, and the mixture is exposed to electric stabilisation by sending alternating current pulses, the current density of which is in the range of 10-49 A/m2, with duration of 3-7 min with a stop before each change of polarity of the pulse for more than 2 min. At the same time in process of mixture pouring into a curb, cassette or a form the mixture is exposed to vibration, then into the poured mix they install an emitter and a receiver of ultrasound at the fixed distance, for instance, 1 m. Ultrasound pulses, which are recorded in the ultrasound receiver, are generated in the emitter via identical equal time intervals, in the period of each pause before each change of polarity of the current pulse. Duration of the specified fixed distance travelling by each ultrasound pulse is determined, and by results of the measurements they calculate the value α according to the given mathematical expression. At that moment of time, when the value α takes the value below 1, they disconnect the pulse current and perform secondary vibration of the mix poured into the curb, cassette or form for 1-2 minutes. Afterwards the product is maintained for 5-6 hours until structural strength is achieved.

EFFECT: increased efficiency and improved characteristics of manufactured products.

SUBSTANCE: invention relates to a novel method of making articles in form of slabs, porous slabs, blocks made from a conglomerate consisting of pieces of stone. The method is based on the existing technology of compaction by means of vacuum compression and involves preparation of a mixture consisting of a granulate and binder which is an aqueous dispersion of an acrylic prepolymer. The granulate is selected from stone-like materials. The mixture also contains a finely dispersed inorganic aggregate. The mixture is deposited in form of a layer onto a substrate or inside a mould and is compacted via vacuum vibro-compression. Further, the binder which is present in the moulded article is hardened. At the step for compaction using vacuum vibro-compression, the article hardens in conditions which enable to prevent removal of water from the mixture due to evaporation. When making porous slabs, at the compacting step, the article hardens in conditions which enable to remove water from the mixture. When making blocks, the mixture is deposited only inside the mould. When using the method, blocks can also be made, which can then be sawed.

EFFECT: articles have high mechanical strength, resistance to UV radiation and are environmentally safe.
