Description
дает абсолютную деформацию испытываемого сло бетона. В случае проскальзывани стержн в конусе вводитс соответствующа поправка на основании измерений, осуществл емых тензорезисторами анкерного стержн .gives the absolute deformation of the test layer of concrete. In the case of a rod slipping in a cone, a corresponding correction is introduced based on measurements made by anchor rod strain gauges.
Полученные данные используют дл построени зависимости «напр жение - деформаци испытываемого сло бетона. При этом совершенно необ зательно доводить бетон до разрушени , так как навальный илн касательный модуль упругости бетона может быть определен по полученному участку диаграммы «напр жение - деформаци . По модулю можеть быть установлена марка бетона. Необходимо иметь в виду, что напр женное состо ние бетона под штампом и в образце - кубе различно , поэтому переводной коэффициент дл модул упругости должен определ тьс расчетно-аналитическим The data obtained are used to construct the stress-strain relationship of the test concrete layer. In this case, it is absolutely unnecessary to bring concrete to fracture, since the bulk or tangential modulus of elasticity of concrete can be determined from the resulting section of the stress – strain diagram. Modulo can be installed brand of concrete. It must be borne in mind that the stress state of the concrete under the stamp and in the sample cube is different, therefore the conversion factor for the elastic modulus must be determined by the calculation and analysis
методом и уточн тьс экспериментально.method and refined experimentally.
