Description
(54) РАСШИРЯЮЩИЙСЯ ЦЕМЕНТ(54) EXPANDING CEMENT
1one
Изобретение относитс к строительным материалам.The invention relates to building materials.
Безусадочные и расшир ющиес композиции изготавливают с применением специально приготовленных добавок, глиноземистого цемента и других дорогосто щих и дефицитных продуктов.Известен расщир ющийс це мент включаюиИй шлакопорт андцемент,извес и сиштоф. Однако такой состав не обеспечи-iвает всех возможностей добавки по расшире- нию, цемента и прочностным его свойствам. Кроме этого, в воздушных услови х твердени наблюдаетс некотора усадка.Non-shrinking and expanding compositions are made using specially prepared additives, aluminous cement and other expensive and scarce products. Known for the expanding cement including slag port and cement, lime and sistof. However, such a composition does not provide all the possibilities of the expansion agent, cement and its strength properties. In addition, some shrinkage is observed in air curing conditions.
Цель изобретени - уменьшение усадки Б воздушных услови х твердени , повышениеэффекта расширени при твердении в воде и повышение прочности.The purpose of the invention is to reduce shrinkage B of air hardening conditions, increase the expansion effect during hardening in water and increase strength.
Это достигаетс тем, что расшир ющийс цемент дополнительно содержит неорганическую соль, например, хлористый кальций, в количестве 0,5-1,5% при следующем соотношении компонентов, вес. ч:This is achieved by the fact that the expanding cement additionally contains an inorganic salt, for example, calcium chloride, in an amount of 0.5-1.5% in the following ratio of components, weight. h:

2,7-13,5 9-11 0,5-1.52.7-13.5 9-11 0.5-1.5
Указанный состав быстро твердеет и дае более эффективное расширение в ранние сроки . Более того, к одним суткам твердени на воздухе наблюдаетс не усадка, а увеличение объема цементного камн . Добавка хлористого кальци в оптимальных количествах способствует значительному повышению прочности цемента.The composition indicated hardens rapidly and makes more effective expansion at an early date. Moreover, by one day of air cure there was not a shrinkage, but an increase in the volume of cement stone. The addition of calcium chloride in optimal quantities contributes to a significant increase in cement strength.
В таблице приведены свойства гфедлагаемого расшир ющегюс цемента.The table shows the properties of the hydrated expanding cement.
