FIELD: construction.

SUBSTANCE: invention relates to industry of construction materials and can be used in making wall articles in form of non-fired bricks and blocks. Method of making wall articles, involving mixing components of crude mixture to a homogeneous state, moulding with a seal, hardening and drying crude mixture in following proportions, wt%: 0-5 mm fraction burnt clay - 68-78, cement - 8-17, chemical modifier - 0.3-0.5 % of mass of cement, water - balance, moulding with a seal is performed at pressure 20.0-32.0 MPa to value of seal within 1.59-1.64 while hardening of moulded articles is carried out on trays in steps under waterproof film, wherein at first step hardening is performed at 35-45 °C for not less than 12 hours, and at second step - at 20-35 °C for 12 hours.

EFFECT: high strength and uniformity of wall material - unfired bricks based on burnt clay; higher efficiency of its production.
