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 смеси на основе минерального вяжущего (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 a layer of a mixture based on a mineral binder (cement paste) with its 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 заполнителя слоя смеси на основе минерального вяжущего с последующим его твердением, в качестве заполнителя используют щебень из доменного шлака, а в качестве смеси на основе минерального вяжущего - смесь шлакопортландцемента с песком, полученным дроблением доменного шлака, взятых в массовом соотношении 1:3-1:2, при водоцементном отношении 0,8-1,2.The technical result is achieved by the fact that according to the method of manufacturing a large aggregate for concrete, including applying to the surface of the aggregate a layer of a mixture based on a mineral binder followed by hardening, blast furnace slag is used as a filler, and a mixture of slag Portland cement is used as a mixture based on a mineral binder with sand obtained by crushing of blast furnace slag taken in a mass ratio of 1: 3-1: 2, with a water-cement ratio of 0.8-1.2.
Примеры соотношения шлакопортландцемента с песком, полученным дроблением доменного шлака, приведены в таблице.Examples of the ratio of slag Portland cement to sand obtained by crushing blast furnace slag are given in the table.
Способ поясняется следующим примером.The method is illustrated by the following example.
Песок, полученный дроблением доменного шлака, смешивают со шлакопортландцементом и водой. Щебень из доменного шлака, например фракции 20-40 мм, погружают в емкость с приготовленной смесью. После обволакивания смесью щебня заполнитель извлекают из емкости и укладывают в один слой, например на сетку, и отставляют до затвердевания смеси на его поверхности. Возможно нанесение нескольких слоев смеси на поверхность щебня. При этом каждый последующий слой наносят после отверждения предыдущего. Готовый заполнитель используют по назначению.Sand obtained by crushing blast furnace slag is mixed with slag Portland cement and water. Crushed stone from blast furnace slag, for example, fractions of 20-40 mm, is immersed in a container with the prepared mixture. After enveloping with a mixture of crushed stone, the aggregate is removed from the tank and laid in one layer, for example on a grid, and set aside until the mixture hardens on its surface. It is possible to apply several layers of the mixture on the surface of crushed stone. Moreover, each subsequent layer is applied after curing the previous one. Ready placeholder is used as intended.
Использование предложенного способа повышает сцепление (на 10-20%) заполнителя с цементным камнем бетона.Using the proposed method increases the adhesion (10-20%) of the aggregate with concrete cement stone.
