Abstract
1. Способ цементации слабых грунтов, включающий приготовление водной суспензии цемента с тонкодисперсным минеральным компонентом и введение в грунт приготовленной суспензии, отличающийся тем, что в качестве тонкодисперсного минерального компонента используют карбонатный шлам химводоподготовки для котельных установок ТЭС или ТЭЦ. ! 2. Способ цементации слабых грунтов по п.1, отличающийся тем, что водная суспензия цемента с добавкой карбонатного шлама содержит указанные компоненты в следующем соотношении, мас.%: ! портландцемент41,7-66,9карбонатный шлам3,4-22,3водаостальное ! 3. Способ цементации слабых грунтов по п.1, отличающийся тем, что тонкодисперсный минеральный компонент, в качестве которого используют карбонатный шлам химводоподготовки, вводят в состав твердой фазы цементно-водной суспензии в количестве 5-35 мас.% перед приготовлением указанной суспензии. ! 4. Способ цементации слабых грунтов по п.1, отличающийся тем, что максимальное значение концентрации Cm карбонатного шлама в составе твердой фазы (в мас.%), при котором происходит повышение механической прочности цементационного раствора после отверждения, определяют по формуле ! , ! где В/Ц - водоцементное отношение цементационного раствора без добавления карбонатного шлама.1. A method of cementing soft soils, including the preparation of an aqueous suspension of cement with a finely divided mineral component and the introduction of the prepared slurry into the soil, characterized in that the carbonate slurry of chemical water treatment is used as a finely dispersed mineral component for boiler plants of thermal power plants or thermal power plants. ! 2. The method of cementing soft soils according to claim 1, characterized in that the aqueous suspension of cement with the addition of carbonate sludge contains these components in the following ratio, wt.%:! Portland cement 41.7-66.9 carbonate sludge 3.4-22.3 water else! 3. The method of cementing soft soils according to claim 1, characterized in that the finely dispersed mineral component, which is used as a carbonate slurry of chemical water treatment, is introduced into the composition of the solid phase of a cement-water suspension in an amount of 5-35 wt.% Before preparing said suspension. ! 4. The method of cementing soft soils according to claim 1, characterized in that the maximum concentration Cm of carbonate sludge in the composition of the solid phase (in wt.%), At which the mechanical strength of the cementitious mortar after curing increases, is determined by the formula! ! where W / C is the water-cement ratio of the cementitious mortar without the addition of carbonate sludge.
