Изобретение относится к области производства строительных материалов и может быть использовано при производстве безусадочных, расширяющихся и напрягающих цементов, в уплотнении структуры цементного камня и уменьшении проницаемости вяжущего на основе предлагаемой расширяющей добавки, а также упрощении технологии ее приготовления. Расширяющая добавка содержит в мас.%: тонкомолотую слюду - 40 - 60; тонкомолотый диопсид - 5 - 15; гипс - 35 - 45. Добавку вводят в цемент в процессе приготовления бетонной смеси. Прочность при сжатии 40 - 43 МПа, сопротивление проницаемости воздуха 50 - 80 с/см3.The invention relates to the field of production of building materials and can be used in the production of non-shrinking, expanding and annoying cements, in densifying the structure of cement stone and reducing the binder permeability based on the proposed expanding additive, as well as simplifying the technology for its preparation. The expanding additive contains in wt.%: Finely ground mica - 40-60; finely ground diopside - 5 - 15; gypsum - 35 - 45. The additive is introduced into the cement during the preparation of the concrete mixture. The compressive strength is 40 - 43 MPa, the resistance to air permeability is 50 - 80 s / cm 3 .
