Abstract

1. СПОСОБ ЗИМНЕГО БЕТОНИРОВАНИЯ , включающий укладку бетонной смеси, обогрев ее нагретым воздухом с последующим укрытием теплоизолирующим материалом, отличающийс  тем, что, с целью обеспечени  заданной прочности и повышени  морозостойкости бетона без увеличени  расхода электроэнергии, обогрев бетонной смеси до начала твердени  осуществл ют нагретым до температуры 50-60 С воздухом, увлажненным водным раствором поташа. 2. Способ поп.1,отлича ющ и и с   тем, что увлажнение нагреi того воздуха производ т 2%-ным водным раствором поташа с расходом 25 (Л 27 г/м.1. METHOD FOR WINTER CONCRETING, which includes laying the concrete mixture, heating it with heated air and then covering it with heat insulating material, characterized in that, in order to ensure the specified strength and increase the frost resistance of the concrete without increasing the power consumption, the concrete mixture is heated before temperature 50-60 With air moistened with an aqueous solution of potash. 2. The method of pop. 1, which differs from the fact that the moistening of the heated air is carried out with a 2% aqueous solution of potash with a flow rate of 25 (L 27 g / m.
