METHOD FOR CONTROLLING CONCRETE SHRINKAGE Russian patent published in 2007 - IPC G05D21/00 

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 e_s and conditions of thermo-moisture processing - duration τ, temperature t and moisture φ - of filler is determined, and thermo-moisture processing of filler is performed with value τ₀,t₀,φ₀, providing required shrinkage of concrete e_y0, and consideration of this relation.

EFFECT: increased range and increased precision of monitoring over concrete shrinkage by means of thermo-moisture processing of filler.
