Abstract
Изобретение относитс к строительным материалам, в частности к способам приготовлени бетонных смесей, используемых при изготовлении дорожных и аэродромных покрытий, монолитных конструкций в зимних услови х . Цель изобретени - ускорение набора прочности бетона при температуре до -25°С, повышение прочности на сжатие, морозостойкости и водонепроницаемости бетона. Способ приготовлени бетонной смеси включает перемешивание портландцемента, заполнител и диметилдихлорсилана, затем в полученную смесь ввод т воду при следующем соотношении компонентов, мас.%: портландцемент 40-50, заполнитель 35-45, диметилдихлорсилан 1-2 и вода - остальное. Прочность бетона при температуре твердени - 25°С через 90 сут составл ет 60% от прочности бетона через 28 сут нормального твердени , прочность бетона при сжатии через 28 сут нормального твердени 79,8 МПа, морозостойкость 550 циклов, водонепроницаемость 0,79 МПа. 2 табл. О S (ЛThe invention relates to construction materials, in particular, to methods for preparing concrete mixtures used in the manufacture of road and airfield coatings, monolithic structures in winter conditions. The purpose of the invention is to accelerate the curing of concrete at a temperature of up to -25 ° C, increasing the compressive strength, frost resistance and water resistance of concrete. The method of preparing a concrete mix includes mixing Portland cement, aggregate and dimethyldichlorosilane, then water is added to the resulting mixture in the following ratio of components, wt%: Portland cement 40-50, aggregate 35-45, dimethyldichlorosilane 1-2, and water — the rest. The strength of concrete at a hardening temperature of 25 ° C after 90 days is 60% of the strength of concrete after 28 days of normal hardening, the strength of concrete under compression after 28 days of normal hardening is 79.8 MPa, frost resistance of 550 cycles, water tightness of 0.79 MPa . 2 tab.

Цель изобретени - ускорение набора прочности бетона при температуре до -25°С, повышение прочности на сжатие, морозостойкости и водонепроницаемости бетонаThe purpose of the invention is to accelerate the curing of concrete at temperatures up to -25 ° C, increasing the compressive strength, frost resistance and water resistance of concrete
Бетонную смесь готов т по следующей методике Вначале смешивают портландцемент М-500, песок речной с МКр 1,5, щебень с модулем крупности до 20 мм при СООТНОШЕНИИ мелкого заполнител к крупному 1:1,5 и диметилдихлорсилан , а затем в смесь ввод т воду затворени .,The concrete mix is prepared according to the following procedure. First, Portland cement M-500 is mixed, river sand with a MKp of 1.5, crushed stone with a modulus of 20 mm in size at a ratio of 1: 1.5 to a coarse aggregate and dimethyldichlorosilane, and then water is introduced into the mixture shutter.,
Составы бетонных смесей, приготовленных без добавки, по известному и предлагаемому способам, а также результаты твердени бетона при отрицательных температурах представлены в табло 1; физико-механические показател указанных бетонных смесей - в табл. 2.The compositions of concrete mixtures prepared without additives, according to the known and proposed methods, as well as the results of the hardening of concrete at negative temperatures are presented in board 1; physical and mechanical indicators of these concrete mixtures - in Table. 2
