Description
(54) СПОСОБ ЗАЩИТЫ СВЕЖЕУЛОЖЕННОГО БЕТОНА(54) METHOD OF PROTECTING FRESH CONVERTED CONCRETE
дочны деформаций в бетоне и повыlueHtuo его прочности.Daughters of deformations in concrete and increasing its strength.
Пример. На свежеотформованные бетонные образцы-призмы размерами 7x7x28 см нанос т грунтовку состава, масс.ч.:Example. On freshly molded concrete prism samples measuring 7x7x28 cm, a primer was applied, mass:
Эпоксидна смола ЭД-20 31 Аминофёнольный отвердитель 7Epoxy resin ED-20 31 Aminophenol hardener 7
Ацетон62Acetone62
Затем укладывают поочередно эпоксидно-фурановую наполненную композицию состава, масс.ч.:Then alternately stack epoxy-furan filled composition of the composition, wt.h .:

Затем бумагу толщиной 0,03-0,1мм снова эпоксидно-фурановую наполненную композицию. Параллельно выполн ют защиту свежеформованных бетонных призм по известному способу.Then the paper thickness of 0.03-0.1 mm again epoxy-furan filled composition. At the same time, freshly molded concrete prisms are protected by a known method.
Во всех образцах толщина грунтовки составл ет 0,1-0,2 мм. Толщинатрехслойного покрыти по предлагаемому способу составл ет 1,1-1,2 мм, а толщина покрыти по известному способу - 1-1,2 мм. Все образцы твердеют 28 дней при 18-22°С и влажности воздуха 65-68%. Измерение усадочных деформаций производ т с помощью мессур часового типа с ценой делени 0,002 мм.In all samples, the primer thickness is 0.1-0.2 mm. The thickness of the three-layer coating according to the proposed method is 1.1-1.2 mm, and the coating thickness by the known method is 1-1.2 mm. All samples harden for 28 days at 18-22 ° C and air humidity of 65-68%. The measurement of shrinkage deformations is carried out using clock-type mesur with a division value of 0.002 mm.
Результаты испытаний бетонных образцов по предлагаемому и известному способам представлены в таблице.The test results of concrete samples on the proposed and known methods are presented in the table.
