Abstract
Description
Изобретение относится к области строительства и может быть использовано при производстве строительных растворов и изделий: кирпича, силикатного бетона и т.д.The invention relates to the field of construction and can be used in the manufacture of mortars and products: brick, silicate concrete, etc.
Известен способ получения вяжущего, включающем раздельный помол негашеной извести и кварцевого песка с последующим их смешением, помол кварцевого песка осуществляют мокрым способом с получением высококонцентрированной суспензии с влажностью 12-20% и содержанием частиц менее 5 мкм 20-50% и при следующем соотношении компонентов, мас. %: указанная суспензия (на сухое) 15-25, известь негашеная 75-85 (RU 2376258 С1 опуб. 20.12.2009, бюл. №35).A known method of producing a binder, including separate grinding of quicklime and quartz sand, followed by mixing them, grinding quartz sand is carried out wet to obtain a highly concentrated suspension with a moisture content of 12-20% and a particle content of less than 5 microns 20-50% and in the following ratio of components, wt. %: the specified suspension (dry) 15-25, quicklime 75-85 (RU 2376258 C1 publ. 12/20/2009, bull. No. 35).
Недостатком данного изобретения является усложнение процедуры помола, заключающемся в необходимости раздельного помола извести и песка, а также высокий расход извести, превышающий расход песка в 3-5 раз.The disadvantage of this invention is the complication of the grinding procedure, which consists in the need for separate grinding of lime and sand, as well as high consumption of lime, exceeding the consumption of sand by 3-5 times.
Известен способ получения известково-кремнеземистого вяжущего, заключающийся в совместном помоле извести и песка, взятых в определенных соотношениях (Технология изделий из силикатных бетонов / А.В. Саталкин М.: Издательство литературы по строительству, 1972. - 335 с.).A known method of producing a lime-silica binder, consisting in the joint grinding of lime and sand, taken in certain proportions (Technology of products from silicate concrete / A.V. Satalkin M .: Publishing house of construction literature, 1972. - 335 S.).
Недостатком данного способа активации является использование шаровой мельницы, где происходит быстрое истирание как мелющих тел, так и футеровки, так как процесс помола длится 1,0-1,5 часа, повышая при этом энергозатраты.The disadvantage of this activation method is the use of a ball mill, where there is a quick abrasion of both grinding bodies and the lining, since the grinding process lasts 1.0-1.5 hours, while increasing energy consumption.
Известен способ совместной активации извести и песка в дезинтеграторах (основы производства силикальцитных изделий / Й.А. Хинт М: государственное издательство литературы по строительству, архитектуре и строительным материалам, 1962. - 642 с. )There is a method of joint activation of lime and sand in disintegrators (the basis for the production of silicalcite products / Y. A. Hint M: state publishing house of literature on construction, architecture and building materials, 1962. - 642 S.)
Недостатком такого решения является сложность устройства дезинтегратора, высокий износ рабочих пальцев за короткий промежуток времени, а также высокие энергозатраты на помол вяжущего.The disadvantage of this solution is the complexity of the disintegrator device, the high wear of the working fingers in a short period of time, as well as the high energy consumption for grinding the binder.
Прототипом данного изобретения является известково-кремнеземистое вяжущее, включающее помол негашеной извести и кварцевого песка, отличающийся тем, что в процессе измельчения дополнительно вводят 1,80-8,09%-ный водный раствор медного купороса, имеющий температуру 0-55°С, при следующем соотношении компонентов, масс. %: молотый кварцевый песок 10,59-30,51; известь негашеная 22,00-36,99; водный раствор медного купороса 46,61-57,63 (RU 2303013 С1 опуб. 20.07.2007, бюл. №20).The prototype of this invention is a lime-silica binder, including grinding quicklime and silica sand, characterized in that during the grinding process, an additional 1.80-8.09% aqueous solution of copper sulfate is added, having a temperature of 0-55 ° C, at the following ratio of components, mass. %: ground quartz sand 10.59-30.51; quicklime 22.00-36.99; an aqueous solution of copper sulfate 46.61-57.63 (RU 2303013 C1 publ. 20.07.2007, bull. No. 20).
Недостатком данного изобретения является невысокая прочность получаемых строительных изделий, технологическая сложность процесса активации.The disadvantage of this invention is the low strength of the obtained building products, the technological complexity of the activation process.
Задача настоящего изобретения - повышение прочности строительных изделий на сжатие.The present invention is to increase the compressive strength of building products.
Результат достигается тем, что смесь извести и песка в соотношении 1:2-1:3 посредством поступательного движения поршня подают по внутренней полости немагнитной непрерывной трубы в зону вращающихся анизотропных ферромагнитных тел диаметром 0,8-1,5 мм и длиной 5-10 мм, движение которых обеспечивает аппарат с наружным электромагнитным полем, при этом энергонасыщенность и длина рабочей зоны составляет не менее 100 кВт/м и 0,6 м, время активации составляет 2-4 мин., а ось цилиндрической немагнитной трубы выполнена под углом 5-25° по направлению подачи смеси извести и песка.The result is achieved by the fact that a mixture of lime and sand in a ratio of 1: 2-1: 3 is fed through a continuous piston through the internal cavity of a non-magnetic continuous pipe into the zone of rotating anisotropic ferromagnetic bodies with a diameter of 0.8-1.5 mm and a length of 5-10 mm the movement of which is provided by an apparatus with an external electromagnetic field, while the energy saturation and the length of the working zone is at least 100 kW / m and 0.6 m, the activation time is 2-4 minutes, and the axis of the cylindrical non-magnetic pipe is made at an angle of 5-25 ° in the direction of flow and lime and sand.
Изобретение иллюстрируется следующим примером.The invention is illustrated by the following example.
Для приготовления известкового раствора использовали кальциевую негашеную известь, соответствующую ГОСТ 9179-77, песок Камско-Устьинского месторождения, удовлетворяющий требованиям ГОСТ 8736-93 и ГОСТ 8735-88, при следующем соотношении (масс, ч.): известь: песок = 1:3; 1:2.To prepare the lime mortar, we used calcium quicklime, corresponding to GOST 9179-77, sand of the Kama-Ustinsky deposit, meeting the requirements of GOST 8736-93 and GOST 8735-88, in the following ratio (mass, parts): lime: sand = 1: 3 ; 1: 2.
Активацию смеси извести и песка проводили в аппарате вихревого слоя в течении 2-4 мин с использованием в качестве ферромагнитных частиц металлических волоки в виде цилиндров диаметром 0,8-1,5 мм и длиной 5-10 мм. При этом энергонасыщенность рабочей зоны аппарата составила не менее 100 кВт/м, а длина - 0,6 м.The mixture of lime and sand was activated in the vortex layer apparatus for 2-4 min using metal dies as ferromagnetic particles in the form of cylinders with a diameter of 0.8-1.5 mm and a length of 5-10 mm. At the same time, the energy saturation of the working area of the apparatus was at least 100 kW / m, and the length was 0.6 m.
Активированную известь перемешивали с мелким заполнителем, затворяли водой в соответствии с ГОСТ 22688-77.The activated lime was mixed with a fine aggregate, closed with water in accordance with GOST 22688-77.
Физико-механические испытания проводили в соответствии с ГОСТ 310.4-81.Physical and mechanical tests were carried out in accordance with GOST 310.4-81.
Результаты физико-механических испытаний образцов приведены в таблице 1.The results of physical and mechanical tests of the samples are shown in table 1.
Примечание*: над чертой приведено среднее значение показателя; под чертой -относительное значение показателя в % от прототипа.Note *: above the line is the average value of the indicator; under the line is the relative value of the indicator in% of the prototype.
Из данных табл. 1 видно, что известковый раствор, полученный на основе активированной смеси извести и песка, имеет прочность на сжатие в возрасте 28 сут на 31-87% выше прочности известкового раствора, полученному по прототипу.From the data table. 1 shows that the lime mortar obtained on the basis of an activated mixture of lime and sand, has a compressive strength at the age of 28 days at 31-87% higher than the strength of the lime mortar obtained by the prototype.
