Abstract
Изобретение относитс к области технологии бетона и направлено на повьшение водонепроницаемости бетона . Способ приготовлени бетонной смеси заключаетс в перемешивании цемента, мелкого и крупного заполнител и введении алюмокалиевых квасцов в количестве 0,5-1,2% от массы цемента и карбоната кали в количестве 0,3-0,6% от массы цемента с водой затворени . 2 табл. (ЛThe invention relates to the field of concrete technology and is aimed at increasing the water resistance of concrete. The method of preparing a concrete mix consists of mixing cement, fine and coarse aggregate and introducing potassium alum in an amount of 0.5-1.2% by weight of cement and potassium carbonate in an amount of 0.3-0.6% by weight of cement with mixing water. 2 tab.

Description
Изобретение относится к строительным материалам, в частности к технологии приготовления бетонной смеси, и может быть использовано при производстве сборных железобетонных изделий.The invention relates to building materials, in particular to a technology for the preparation of concrete mixtures, and can be used in the manufacture of precast concrete products.
Цель изобретения - повышение водонепроницаемости бетона.The purpose of the invention is to increase the water resistance of concrete.
Примеры конкретного выполнения бетонных смесей приведены в табл.1.Examples of specific performance of concrete mixtures are given in table 1.
Алюмокалиевые квасцы и карбонат калия вводят раздельно в смесь портландцемента М 400, песка и щебня фракции 5-20 мм при соотношении 1:2,70:3,47 совместно с водой затворения .Potassium alum and potassium carbonate are introduced separately into a mixture of Portland cement M 400, sand and gravel fractions of 5-20 mm fraction at a ratio of 1: 2.70: 3.47 together with mixing water.
Физико-механические показатели бетонных образцов приведены в табл.2.Physico-mechanical properties of concrete samples are given in table.2.
Предлагаемый способ позволяет повысить водонепроницаемость бетона, 20 а также сохранить подвижность бетонной смеси к моменту укладки·ее в фор му. Кроме этого, бетон, приготовленный по предлагаемому способу, способен быстро набирать прочность, необходимую для распалубки бетонных изделий»The proposed method improves the water resistance of concrete, 20 and also maintains the mobility of the concrete mixture at the time of laying · its shape. In addition, concrete prepared by the proposed method is able to quickly gain strength necessary for the dismantling of concrete products "
