FIELD: construction.
SUBSTANCE: method to manufacture haydite concrete blocks with a face texture layer includes preparation of a moulding mass, its laying into a mould in the form of split or detachable casing with a replaceable process tray installed in it and made in the form of a texture matrix. The moulding mass is applied for the face texture layer. At the same time the moulding mass is glass fibre concrete, which is first applied by spraying onto the texture matrix with a layer of 2-4 mm. The moulding mass for the main layer is prepared from the mix of haydite with fractions of 10-20 mm with concrete at the ratio of 65-75% haydite, balance is concrete. The specified mass is poured into the mould in 25-35 minutes after application of the face texture layer to the upper edge of the mould. The contents of the mould are exposed to vibration pressing for 1-2 minutes. The available free space in the mould of 1-2-5 cm to the edges of the mould is poured with concrete without haydite fractions. Afterwards the moulded mass is exposed to additional short-term (several seconds) vibration pressing. The moulded mass is exposed to drying in a drying chamber with subsequent withdrawal of the block from the mould.
EFFECT: expansion of functional capabilities due to production of blocks with stable size, their increased strength and reduced weight.
