Abstract
Description
Изобретение относится к области производства заполнителей для бетонов.The invention relates to the production of aggregates for concrete.
Известен способ изготовления крупного заполнителя для бетонов, включающий нанесение на поверхность зерен заполнителя слоя цементного теста с последующим его твердением [1]. Полученный таким способом заполнитель имеет достаточно ровную поверхность, что снижает прочность его сцепления с цементным камнем бетона.A known method of manufacturing a large aggregate for concrete, including applying to the surface of the grains of the aggregate layer of cement paste with subsequent hardening [1]. The aggregate obtained in this way has a fairly smooth surface, which reduces the strength of its adhesion to the concrete cement stone.
Задача изобретения состоит в повышении прочности сцепления заполнителя с цементным камнем бетона.The objective of the invention is to increase the adhesion strength of the aggregate with concrete cement stone.
Технический результат достигается тем, что по способу изготовления крупного заполнителя для бетонов, включающему нанесение на поверхность зерен заполнителя слоя цементного теста с последующим его твердением, на поверхность слоя до его затвердевания наносят крошку пористого силикатного материала.The technical result is achieved by the fact that according to the method of manufacturing a large aggregate for concrete, including applying a layer of cement dough to the surface of the grains of the aggregate followed by hardening, a crumb of porous silicate material is applied to the surface of the layer before it hardens.
Используют крошку фракции 0.5-5 мм любого природного (пемза, туф) или искусственного (пеностекло, газолит, вспененный шлак и др.) пористого силикатного материала.A crumb of a fraction of 0.5-5 mm of any natural (pumice, tuff) or artificial (foam glass, gasolite, foamed slag, etc.) porous silicate material is used.
Способ поясняется следующим примером.The method is illustrated by the following example.
Подготавливают цементное тесто состава, мас.%: портландцемент 65,0, вода 35,0. Предварительно очищенные (промытые от пыли и грязи) зерна заполнителя, например щебня фракции 20-40 мм, погружают в емкость с цементным тестом После обволакивания тестом зерен заполнитель извлекают из емкости и на его поверхность наносят (напыляют, обваливают) крошку пористого силикатного материала, например пеностекла, фракции 0,5-5 мм. Затем заполнитель укладывают в один слой, например, на сетку.A cement paste of the composition is prepared, wt.%: Portland cement 65.0, water 35.0. Pre-cleaned (washed from dust and dirt) grains of aggregate, for example gravel of a fraction of 20-40 mm, are immersed in a container with cement paste. After enveloping the grains with dough, the aggregate is removed from the container and crushed porous silicate material is applied (sprayed, crumbled), for example foam glass, fractions of 0.5-5 mm. Then the aggregate is laid in one layer, for example, on a grid.
После окончания твердения слоя цементного теста заполнитель используют по назначению. Предложенный способ позволяет повысить прочность сцепления заполнителя с цементным камнем на 5-7% по сравнению с прототипом, т.е. получить прочность сцепления порядка 82 кг/см2.After the hardening of the cement paste layer is completed, the aggregate is used as intended. The proposed method allows to increase the adhesion strength of the aggregate with cement stone by 5-7% compared with the prototype, i.e. to obtain adhesion strength of the order of 82 kg / cm 2 .
