METHOD FOR WINTER CONCRETING OF BUILDING STRUCTURES

摘要

FIELD: construction.;SUBSTANCE: method for winter concreting of building structures includes preparation of a concrete mix and laying of the mix into a formwork as a concreted layer, at the same time blind boreholes are created in the concreted layer, porous inserts are installed into the specified boreholes with provision of capillary removal of released excessive hardening water via the installed inserts, besides, ratios between the depth Hb of boreholes, diameter Db of boreholes, thickness H"п" of the concreted layer and the distance between adjacent boreholes Lb is set in compliance with the following conditions: Hb/H"п"=0.40-0.60, Lb/Hb=0.90-1.10, Db/Hb=0.10-0.20.;EFFECT: improved operating characteristics.;3 tbl, 1 dwg
