Russian term or phrase: равноподвижные растворы
В настоящей статье исследованы технологические, физико-технические свойства и коррозионная стойкость тампонажных цементно-песчаных растворов. Сравнительные данные прочности опытных образцов, изготовленных на равноподвижных растворах состава 1:1 (Ц:П) с использованием речного песка с модулями крупности (Mf): 1.50; 1.35; 1.25, показали наилучшие результаты в последнем случае. Применение пластификатора «Мылонафт М1» в составе раствора в количестве 0.5 % от массы вяжущего с песком с Mf = 1.25 позволили сохранить подвижность 200 мм при В/Ц = 0.6 без потери однородности смеси. Исследование коррозионной стойкости образцов раствора с введением в него 1 % Na2SO4 в процессе его приготовления позволило достичь стойкости в агрессивных сульфатных средах при пониженных (T = 20 °C) и нормальных температурах (T = 5 °C). С целью механизации работ по укреплению лёссовых грунтов тампонажным раствором проведено сравнение традиционного оборудования, используемого в производстве (стационарной растворной станции, с компрессором и насосом) и усовершенствованной мобильной установки УНБ-125×50 СО на базе КамАЗ 363501. Установлена эффективность применения мобильной установки УНБ-125×50 СО, которая позволяет сократить время производства работ и повысить производительность

of equal reactivity


Explanation:
равноподвижные may mean that the solutions are equivalent/identical not in terms of mobility (workability, pumpability, etc.) but in terms of the intensity of the chemical reaction when the ingredients are mixed.

"An element’s chemical activity is defined as its stability relative to the elements surrounding it on the periodic table. Chemical activity is also related to electronegativity. Elements that are highly electronegative are highly reactive, while elements that have low electronegativity are less reactive." https://www.reference.com/science/element-chemically-active-...

Example sentence(s):
  • This makes a very caustic, active solution...
  • Limit the reactive silica content

concrete (mixes) of equal workability


Explanation:
ACI (American Concrete Institute) defines workability as ‘that property of freshly mixed concrete or mortar which determines the ease and homogeneity with which it can be mixed, placed, consolidated and finished’.

ASTM (American Society for Testing and Materials) defines workability as “that property determining the effort required to manipulate a freshly mixed quantity of concrete with minimum loss of homogeneity".

Исходя из контекста "Применение пластификатора «Мылонафт М1» ... позволили сохранить подвижность"

Пластификаторы — это также поверхностно-активные добавки, которые вводят в строительные растворы и бетонные смеси (0,15…0,3 % от массы вяжущего) для облегчения укладки в форму и снижения содержания воды.

https://ru.wikipedia.org/wiki/Пластификаторы

Plasticizers or water reducers, and superplasticizer or high range water reducers, are chemical admixtures that can be added to concrete mixtures to improve workability.
