Beschreibung
Zusammenfassung:	FIELD: building, namely, methods for controlling shrinkage of concrete and solution, used in carrying and limiting concrete and reinforced concrete structures, special and trimming covers. ^ SUBSTANCE: method for controlling concrete shrinkage includes determining properties and flow of binding agent, filler and tempering liquid with production of concrete mixture, its placing, densification and exposure with production of concrete and determining of its shrinkage, relation between concrete shrinkage es and conditions of thermo-moisture processing - duration tau, temperature t and moisture - of filler is determined, and thermo-moisture processing of filler is performed with value tau0,t0, 0, providing required shrinkage of concrete ey0, and consideration of this relation. ^ EFFECT: increased range and increased precision of monitoring over concrete shrinkage by means of thermo-moisture processing of filler. ^ 4 tbl
