Сущность изобретени : способ приготовлени  добавки дл  бетонной смеси включает обработку 0,5-5%-ного водного раствора мелассы на основе углеводородов микроорганизмами Bacillus species с концентрацией 107-108 клеток/мл с последующим выдерживанием полученного раствора при 15-35°С в течение 3-7 сут. Осадка конуса бетонной смеси 10,6 см; прочность бетона на сжатие 37,6 МПа, 2 табл.The method of preparation of additives for concrete mix. Use: area of production of building materials. SUMMARY OF THE INVENTION: A method for preparing an additive for a concrete mix comprises treating a 0.5-5% aqueous solution of hydrocarbon-based molasses with Bacillus species microorganisms with a concentration of 107-108 cells / ml, followed by keeping the resulting solution at 15-35 ° C. for 3-7 days. Sediment cone concrete mix 10.6 cm; concrete compressive strength of 37.6 MPa, table 2.

Description

Изобретение относитс  к области строительных материалов, в частности к спосо - бам приготовлени  добавок, используемых в производстве бетонных изделий.The invention relates to the field of building materials, in particular, to the methods of preparing additives used in the manufacture of concrete products.

Цель изобретени  - повышение прочности бетона при сохранении удобоукладыва- емости бетонной смеси.The purpose of the invention is to increase the strength of concrete while maintaining the workability of the concrete mix.

Способ приготовлени  добавки осуществл ют по следующей методике: раствор ют в воде мелассу до концентрации 0,5-5% и ввод т в раствор-микроорганизмы Bacillus species в количестве 107-108 клеток/мл раствора .The method of preparation of the additive is carried out according to the following method: the molasses is dissolved in water to a concentration of 0.5-5% and introduced into the solution-microorganisms of Bacillus species in an amount of 107-108 cells / ml of solution.

Бетонную смесь готов т путем смешени  портландцемента М-400, кварцевого пескасМкр 2,2 и грави  из потных горных пород с наибольшей крупностью зерен 20 мм при массовом соотношении Ц : П : Г 1Concrete mixture is prepared by mixing Portland cement M-400, quartz sand Mkr 2.2 and an engraving of sweaty rocks with the largest grain size of 20 mm at a mass ratio of C: P: T 1

: 1,5 : 4,7 и В/Ц 0.62:-добавку ввод т в бетонную смесь с водой затворени  в количестве 0,1 % от массы цемента.: 1.5: 4.7 and V / C 0.62: The additive is introduced into the concrete mix with mixing water in an amount of 0.1% by weight of cement.
