Изобретение относитс к способам приготовлени в жущих дл дорожного бетона.This invention relates to methods for preparing concrete for road concrete.
Известен способ приготовлени в жущего дл дорожных бетонов путем перемешивани битума с углем.There is a known method of making concrete for road concrete by mixing bitumen with coal.
Цель изобретени - повышение однородности в жущего.The purpose of the invention is to increase the homogeneity of the user.
Это достигаетс согласно изобретению тем, что указанные материалы в процессе перемешивани подвергают измельчению при температуре ниже термического разложени угл до размера частиц последнего пор дка 1-100 мк.This is achieved according to the invention by the fact that these materials during grinding are subjected to grinding at a temperature below the thermal decomposition of coal to a particle size of the last order of 1-100 microns.
Не подверга уголь термическому разложению, изобретение предусматривает использовать специфические свойства угл дл получени однородной смеси.Without subjecting coal to thermal decomposition, the invention contemplates the use of the specific properties of coal to obtain a uniform mixture.
В качестве угл могут быть исползованы торф, лигнит, бурый уголь, жирный уголь или подобные материалы , вз тые в отдельности или в виде смеси. Уголь представл ет собой органический материал, состо щий главным образом из углерода, водорода и кислорода, в. также содержащий в небольших количествах такие метал.гш, как V, Ni, Со, Fe, Mg-, Mn,As coal, peat, lignite, brown coal, fat coal or similar materials can be used, taken alone or as a mixture. Coal is an organic material consisting mainly of carbon, hydrogen and oxygen, c. also containing in small quantities metal metals such as V, Ni, Co, Fe, Mg-, Mn,
Sn, Pfo, 2f, Ge и т.д. Уголь вл етс пористым материалом и на его поверхности раздела имеютс различные химическиактивные или функциональные группы, например, карбоксил, карбонил, фенолгидроксил, метоксил и т.д. Уголь обладает также ионообменными свойствами, чем меньше диаметр частиц угл , полученных приSn, Pfo, 2f, Ge, etc. Coal is a porous material and there are various reactive or functional groups on its interface, for example, carboxyl, carbonyl, phenol hydroxyl, methoxy, etc. Coal also has ion-exchange properties, the smaller the particle diameter of the coal obtained by
измельчении, тем больше химически активных групп будет выдел тьс на свежих поверхност х частиц угл , что, в свою очередь, приводит к увеличению активн- сти угл в отношенииgrinding, the more chemically active groups will be released on the fresh surfaces of coal particles, which, in turn, leads to an increase in the activity of coal in relation to
образовани единой смеси. Когда смесь битума и угл подвергаетс измельчению при до 200 С, то генерируема при этом энерги способствует физическим и химическим изменени м .forming a single mixture. When the mixture of bitumen and coal is crushed at up to 200 ° C, the energy generated during this process contributes to physical and chemical changes.
Однако нежелательно/чтобы выдел емое при измельчении тепло способствовало повышению температуры свыше 200с, когда уголь может подвергнутьс термическому разложению. However, it is undesirable for the heat released during grinding to increase the temperature over 200 s, when coal may undergo thermal decomposition.
К используемому битуму предъ вл етс требование, чтобы он обладал текучестью при температуре ниже точки термического разложени угл сBitumen used is required to be fluid at temperatures below the thermal decomposition point of coal with
таким расчетом, чтобы битум можноso that bitumen can be
было легко смешивать во влажном состо нии с углем.it was easy to mix wet with coal.
Вместо асфальтового битума можно использовать гудрон или смесь гудрона и асфальтового битума. Наиболее оптимальный размер размалываемого угл равен от 1 до 30 мк.Instead of asphalt bitumen, you can use tar or a mixture of tar and asphalt bitumen. The most optimal size of grinded coal is 1 to 30 microns.
Смешивание и измельчение битума, и угл предусматриваетс осуществл например, в аппарате непрерывного действи .Mixing and grinding of bitumen and coal is provided for, for example, in a continuous operation apparatus.
Дорожные бетоны, приготовленные на указанном в жущем, обладают высокой термостойкостью, погодоустойчивы , имеют хорошую адгезию, высокие упругопластичные свойстваRoad concretes prepared on the specified tare, have high heat resistance, weather-resistant, have good adhesion, high elastic-plastic properties
и обладают хорошей обрабатываемостью .and have good workability.
