Stenovye from concrete produce stones, from cellular easy concrete, without emptiness (continuous) and hollow (on porous fillers). Hollow stones happen through and with closed shchelevidnymi emptiness. Stones subdivide: the cores (the size 390Х190Х188мм) and additional. The additional stones corresponding to three quarters and half of the basic stone, use for bandaging of a laying and formation of quarters in apertures. From concrete stones put up walls in the thickness 90, 190, 240, 290, 390мм and above. Weight of the stones applied to a laying of a land part of buildings, 14... 25кг.
To a laying of walls from natural stones apply, as a rule, pilenye stones from easy breeds in the size 390X190X188; 490X240X188 and 390X190X288мм, and also additional, equal to three quarters or half of length of the basic stones.

The Laying from continuous and hollow concrete and natural stones conduct with displacement of cross-section vertical seams in adjacent numbers on a quarter or a half-stone. Sequence of performance of operations the same, as at a laying from ceramic stones. A laying from the continuous and hollow stones having smooth end faces, tie up on dvuhrjadnoj to system (fig. 89, and, with packing tychkovyh numbers through everyone two lozhkovyh a number or with bandaging tychkami through everyone lozhkovyj a number (fig. 90,).

Sometimes to the irresponsible poorly loaded designs apply a laying from concrete stones with through emptiness without cross-section bandaging, thus in horizontal seams necessarily stack cross-section steel sheaves not less often than through 2... 3 numbers on wall height. The number and section of these communications specify in the project.
The Thickness of seams in a laying from concrete and natural stones should be same, as well as in a laying from a brick or ceramic stones (horizontal not less 10мм and no more 15мм; vertical - limits 8... 15мм). At a laying lozhkovyh numbers (fig. 90, and, the mason of 2nd rjazrjada costs ahead of the mason of 4th category.
Moving in the laying direction, the first submits stones on a wall and establishes them with the intervals equal approximately to length of one stone. An apportion of stones begin on distance 2... 2,5 lengths of a stone from a place of a laying for lozhkovo th number to take place for the device rastvornoj beds.
At a laying tychkovyh numbers (fig. 90, stones preliminary display on a wall on distance 80... 100мм one from another.
Carrying out a laying, the mason puts kelmoj on the top surface of the stone put on a wall two strips from a solution in width on 60мм. Then takes a stone two hands and, gradually turning it on 90° presses closely to earlier laid stone, rebuffing it on bed from a solution, pressing of both hands, and acting of seams on an obverse surface of a laying the solution cuts off kelmoj and dumps on a laying. For filling of cross-section seams a solution in addition throw in a seam from above kelmoj.
The Laying from legkobetonnyh stones with closed shchelevidnymi emptiness (not through) on a way of manufacture does not differ from a laying from continuous stones as stones stack emptiness downwards. A laying tie up and form quarters in apertures by means of not half-number stones and the stones having quarters for apertures. With that end in view alternate numbers of a laying from the whole stones and longitudinal halves with which provide displacement of longitudinal seams of a laying on half of stone (fig. 91).

The Laying from concrete and other stones in weight to 16кг is carried out by a link "фтющър" at heavier stones - "=Ёющър" as for lifting and packing of stones efforts of two persons are required. A workplace at a laying from concrete stones will organise basically the same as and at a bricklaying.
