Description
ладку декоративного заполнител в форму, заливку его водой на высоту вскрыти и охлаждение до состо ни льда, укладку бетонной смеси на него, виброуплотнение смеси и твердние с оттаиванием льда и стоком вод в бетонную смесь предварительно ввод т противомороэную добавку и охлаждают до +1-0С перед укладкой на слой льда, а оттаивание последнего и сток воды осуществл ют после твердени издели .decorating a decorative filler into the form, opening it with water to a height and cooling it to ice, laying the concrete mix onto it, vibrating the mixture and solid with ice thawing and water flow into the concrete mix are pre-charged with antifreeze and cooled to + 1-0C before laying on the ice layer, and thawing of the latter and the water flow are carried out after the product has hardened.
Способ осуществл етс следующим образом.The method is carried out as follows.
В форму насыпают слой щебн узкой фракции, Например фракции 3040 мм.A layer of crushed stone of a narrow fraction is poured into the form, for example, a fraction of 3040 mm.
Рабочее вещество, воду заливают в форму в объеме, достаточном дл образовани необходимого прин того сло - глубины вскрыти структуры.The working substance, water, is poured into the mold in a volume sufficient to form the necessary adopted layer — depth of the opening of the structure.
Затем форму, слой щебн и рабочее вещество, воду охлаждают до превращени рабочего вещества в твердое состо ние. После отвердевани рабочего вещества в форму заливают бетонную смесь. Чтобы обеспечить возможность затвердевани бетонной смеси при минусовых температурах , в бетонную смесь ввод т противоморозные добавки (3% хлористого ;натри , 4,5% хлористого кальци , 5-10% нитрита натри от массы цемента ) .IThen the form, the layer of rubble and the working substance, the water is cooled to turn the working substance into a solid state. After the working substance has hardened, the concrete mix is poured into the mold. In order to allow the concrete mixture to harden at sub-zero temperatures, antifreeze additives (3% chloride; sodium, 4.5% calcium chloride, 5-10% sodium nitrite by weight of cement) are introduced into the concrete mixture. I
Температуру бетонной смеси перед заливкой, равную 0°С, обеспечивают применением охлажденных заполнителей , цемента и воды затворени с добавками.The temperature of the concrete mix prior to casting is 0 ° C, provided by the use of chilled aggregates, cement and mixing water with additives.
После отвердевани бетонной смеснабора ею распалубочной прочности форму нагревают и изделие вынимают из формы. Способ наиболее целесообразно примен ть в примере с водой в зимнее врем , когда на охлаждение воды нет необходимости дополнительно затрачивать анергию, охлаждение может быть произведено на открьатом воздухе.After the concrete mixing set hardens, the form-breaking strength of the mold is heated and the product is removed from the mold. The method is most expedient to use in the example with water in winter, when it is not necessary to spend additional energy on cooling water, cooling can be performed on open air.
П р и м е р. На дно формы укладывают слой щебн гранитного фракции 30-40 мм, заливают на высоту 10 мм водой, охлаждают до , на образовавшийс лед заливают бетонную смесь и добавкой 3%-ного .хлористого натри и охлажденную до 0°С производ т виброуплотнение смеси и отверждают изделие при отрицательной температуре до набора распалубочной прочности. Затем форму нагревают, производ т оттаивание льда и сток воды и распалубку издели .PRI me R. A layer of rubble of granite fraction 30-40 mm is placed at the bottom of the mold, poured to a height of 10 mm with water, cooled to, the concrete mixture is poured onto the formed ice and the mixture is cooled to 0 ° C and the mixture is vibrated the product at a negative temperature to set stripping strength. Then the mold is heated, the ice is thawed out and the water is drained and the product is dismantled.
