Description
(54) СПОСОБ ФОРМОВАНИЯ БЕТОННЫХ ИЗДЕЛИЙ(54) METHOD OF FORMING CONCRETE PRODUCTS
чально сложившейс структуры смеси с исключением свободных проходов дл воздуха с поверхности внутрь формуемой массы к-пористому заполнителю,the initially formed mixture structure with the exception of free air passages from the surface inward of the formable mass to the porous aggregate,
На втором этапе уплотнени при одновременной работе вибропригруза создаетс перепад давлени снаружи и внутри издели . При этом пористый заполнитель наход щийс внутри отформованного издели , благодар разнице давлений интенсивно впитывает- воду, пары воды и воздух из о.сружающей его бетонной смеси, повыша ее плотность.At the second stage of compaction, with simultaneous operation of the vibration unit, a pressure drop is created outside and inside the product. At the same time, the porous aggregate inside the molded product, due to the pressure difference, intensively absorbs water, water vapor and air from the concrete mixture discharging it, increasing its density.
Одновременно происходит уменьшение объема и уплотнение всего издели за счет поверхностного давлени и работы вибропригруза.At the same time, the volume and compaction of the entire product is reduced due to the surface pressure and the operation of the vibration unit.
Дл увеличени эффекта уплотнени и достижени более высокой прочности бетона в нем увеличивают количество пористого заполнител и степень разрежени в камере при формировании издели .To increase the compaction effect and to achieve a higher concrete strength in it, the amount of porous aggregate and the degree of vacuum in the chamber increase when the article is formed.
Пример . в качестве пористого заполнител берут керамзит с пористостью гранул до 80%, а в окружающей гранулы среде создают разрежение 0,1 атм, при данныхуслови х каждые 100 л керамзита в монолите, введенные в 0,5 м плотной бетонной смеси, отбирают из нее воду, пары и воздух в объеме пор дка 70 л, т.е. способны полностью обезводить бетонную смесь.An example. as a porous aggregate, haydite with a porosity of granules up to 80% is taken, and a vacuum of 0.1 atm is created in the surrounding granules; vapors and air in a volume of about 70 liters, i.e. able to completely dehydrate the concrete mix.
Примен предлагаемый способ формовани бетонных изделий и конструкций из других строительных материалов, полулучают более плотные издели и повышают их прочность не менее чем на 10%, ускор ют процесс твердени изделий при предварительном разогреве бетонной смеси на 1-2 час и используют более подвижные смеси при формовании изделий, что позволит повысить производительность труда на 15-20% и снизить вес изделий на 10-20% без потери их прочности .By applying the proposed method of molding concrete products and structures made of other building materials, semi-radiate denser products and increase their durability by at least 10%, accelerate the process of hardening products during preliminary heating of the concrete mixture for 1-2 hours and use more mobile mixtures during molding. products, which will increase productivity by 15-20% and reduce the weight of products by 10-20% without losing their strength.
