Description
Изобретение относитс к составу бетонной смеси и может найти применение в промьшшенности строительных материалов при изготовлении низко- марочных бетонов дл закладки выработанного пространства.The invention relates to the composition of a concrete mix and can be used in the industrial construction of low grade concrete for laying out the space.
Цель изобретени - повышение проности при сжатии в 28-ми суточном возрасте.The purpose of the invention is to increase the permeability during compression at the age of 28 days.
Пример. Бетонную смесь готов т путем перемешивани заполнител , электросталеплавильного тонкодисперсного шлака и портландцемента с последующим введением в полученну смесь воды затворени с введенной в нее добавкой.Example. The concrete mixture is prepared by mixing the aggregate, the electric steel-smelting fine slag and Portland cement, followed by the introduction of the mixing water into the resulting mixture with the additive introduced into it.
Совместное перемешивание всех компонентов бетонной смеси осуществл ют 10-12 мин. Водоцементное отно шение находитс в пределах 0,4-0,5.The combined mixing of all the components of the concrete mix was carried out for 10-12 minutes. The water-cement ratio is in the range of 0.4-0.5.
Составы бетонных смесей и свойства бетона приведены в табл.1 и 2 соответственно.The compositions of concrete mixes and concrete properties are given in Tables 1 and 2, respectively.
Из табл.2 Jcлeдyeт, что предлагаема бетонна смесь имеет более вы- ,From table 2 it is concluded that the proposed concrete mix has more
