Abstract
Способ определения прочности бетона методом скалывания ребра путем крепления прибора с заданием направления приложения нагрузки к скалывающему элементу под углом к поверхности участка измерения, приложения нагрузки от силового цилиндра к скалывающему элементу с заданной скоростью до момента скола ребра, фиксирования величины прикладываемого усилия и расчетного определения прочности бетона, отличающийся тем, что усилие от силового цилиндра прикладывают непосредственно к скалывающему элементу, при этом заданное направление приложения нагрузки совмещено с осью силового цилиндра.A method for determining the strength of concrete by cleaving a rib by fixing the device with the direction of application of the load to the shear element at an angle to the surface of the measurement site, applying load from the power cylinder to the shear element at a given speed until the edge is cleaved, fixing the magnitude of the applied force and calculating the concrete strength , characterized in that the force from the power cylinder is applied directly to the cleaving element, while the specified direction is applied Load Ia aligned with the axis of the actuator.
