Abstract

Изобретение относится к свежему бетону, который содержит в расчете на 1 мот 135 до 250 кг воды, от 135 до 400 кг цемента или от 135 до 455 кг смеси цемента и заменителей цемента при соотношении цемента и заменителей цемента от 30:70 до 70:30, от 28 до 52 кг микродисперсного диоксида кремния и от 1000 до 2000 кг заполнителя с верхней фракцией вплоть до 16 мм или вплоть до 8 мм, причем от 70 до 100% этого заполнителя составляет кирпичный, или керамический, или смешанный повторно используемый материал, полученный из инертных отходов от строительства и разрушения, с фракцией от 0 до 16 мм или от 0 до 8 мм и/или повторно используемый бетонный материал с фракцией от 0 до 16 мм, или от 1 до 16 мм, или от 0 до 8 мм, или от 1 до 8 мм. Из остальной части заполнителя вплоть до максимума, составляющего 30 мас.%, может составлять природный заполнитель с верхней фракцией вплоть до 16 мм или вплоть до 8 мм. Еще от 0 до 30 мас.% заполнителя может составлять по меньшей мере один известный улучшающий компонент, который улучшает термические, и/или акустические, и/или огнестойкие свойства бетона и который обычно используют в стандартных бетонах. Настоящее изобретение также относится к сухой смеси для получения этого бетона, а также к бетонному изделию или к предварительно изготовленному элементу, полученному из этого бетона. Кроме того, настоящее изобретение относится к способу получения этого свежего бетона.The invention relates to fresh concrete, which contains, per 1 mot, 135 to 250 kg of water, from 135 to 400 kg of cement or from 135 to 455 kg of a mixture of cement and cement substitutes with a ratio of cement and cement substitutes from 30:70 to 70:30 , from 28 to 52 kg of microdispersed silicon dioxide and from 1000 to 2000 kg of aggregate with a top fraction of up to 16 mm or up to 8 mm, and from 70 to 100% of this aggregate is brick, or ceramic, or mixed recycled material obtained from inert waste from construction and destruction, with a fraction of 0 to 16 mm or from 0 to 8 mm and / or recyclable concrete material with a fraction of 0 to 16 mm, or from 1 to 16 mm, or from 0 to 8 mm, or from 1 to 8 mm. The remainder of the aggregate up to a maximum of 30% by weight can be natural aggregate with a top fraction of up to 16 mm or up to 8 mm. A further 0 to 30 wt.% Of the aggregate can be at least one known enhancing component that improves the thermal and / or acoustic and / or fire resistance properties of concrete and which is usually used in standard concrete. The present invention also relates to a dry mix for the production of this concrete, as well as to a concrete product or to a prefabricated element obtained from this concrete. In addition, the present invention relates to a method for producing this fresh concrete.
