1. Способ получения легкого крупноячеистого бетона, включающий подготовку вяжущего раствора, отличающийся тем, что в форму для бетонного изделия помещают крупные гранулы льда, являющиеся временным заполнителем, имеющие температуру не более -5oC, затем заполняют пустоты между гранулами вяжущим раствором с температурой не более +5oC с применением виброуплотнения, а после начального схватывания бетона изделия извлекают из формы, температуру его повышают до +80 - 95oC в течение 20 - 24 ч и выдерживают при указанной температуре до полного освобождения от воды пустот, образованных гранулами льда.1. A method of obtaining light coarse concrete, including the preparation of a binder solution, characterized in that large granules of ice are placed in the form for a concrete product, which are temporary aggregates, having a temperature not exceeding -5 o C, then fill the voids between the granules with a binder solution with a temperature not more +5 o C using a vibrocompaction, but after the initial setting of concrete products extracted from the mold, its temperature is raised to 80 - 95 o C for 20 - 24 hours and kept at this temperature until the freeing Ia water voids formed ice granules. 2. Сырьевая смесь для изготовления легкого крупноячеистого бетона, содержащая цемент, гипс и песок, отличающаяся тем, что в качестве временного заполнителя используют крупные гранулы охлажденного льда и мыльную стружку при следующем соотношении компонентов, мас.%:
Цемент - 20 - 25
Гипс - 2 - 3
Песок - 15 - 20
Мыльная стружка - 0,5 - 1
Гранулированный лед - 55 - 60н2. Raw mix for the manufacture of lightweight coarse-grained concrete containing cement, gypsum and sand, characterized in that large granules of chilled ice and soap chips are used as temporary aggregate in the following ratio, wt.%:
Cement - 20 - 25
Gypsum - 2 - 3
Sand - 15 - 20
Soap chips - 0.5 - 1
Granulated ice - 55 - 60n
