Изобретение относитс к области исследовани строительных материалов и может быть использовано нри изучении свойств твердеющих бетонов и разработки режимов их электропрогрева .The invention relates to the field of research of building materials and can be used to study the properties of hardening concrete and the development of modes of their heating.
Известны способы определени электрического сопротивлени образца твердеющего бетона путем ВКлючени его во внутреннюю электрическую цепь источника тока.Methods are known for determining the electrical resistance of a sample of hardening concrete by switching it on to an internal electrical circuit of a current source.
Недостатком известных способов вл етс мала точность, обусловленна электрохимическими процессами, протекающими под воздействием внешней электрической энергии и искажающими результаты исследований.A disadvantage of the known methods is the low accuracy due to electrochemical processes proceeding under the influence of external electrical energy and distorting the results of research.
Цель изобретени - повышение точности определени электрического сопротивлени .The purpose of the invention is to improve the accuracy of determining electrical resistance.
Указанна цель достигаетс тем, что исследуемый образец помещают между электродами гальванической пары, после чего периодически замыкают внешнюю электроцепь и определ ют внутреннее электрнческое сопротивление образованного гальванического элемента .This goal is achieved by placing the sample under study between the electrodes of a galvanic couple, after which the external electrical circuit is periodically closed and the internal electrical resistance of the galvanic element formed is determined.
На чертеже показана схема подключени элемента к внешней цепи.The drawing shows a circuit for connecting an element to an external circuit.
Способ осуществл етс следующим образом .The method is carried out as follows.
Цинковый электрод 1, выполненный в видеZinc electrode 1, made in the form
стаканчика, заполн ют составом бетона 2, вставл ют в бетон угольный электрод 3 и уплотн ют на виброплощадке.the cup is filled with concrete 2, the carbon electrode 3 is inserted into the concrete and compacted on a vibrating plate.
Затем собирают электрическую схему, в которой к образованному гальваническому элементу подключают автоматический потенциометр 4 и параллельно ему через автоматический переключатель 5 нагрузку (R) 6.Then, an electrical circuit is assembled in which an automatic potentiometer 4 is connected to the formed electroplating element and, in parallel with an automatic switch 5, a load (R) 6 is connected to it.
После этого периодически замыкают внень нюю электроцепь. Замеры Э.Д.С. выполн ют при отключенной нагрузке, а замеры напр жени - при включенной. По величинам Э.Д.С. и напр жени вычисл ют электрическое сопротивление внутренней цепи в каждый момент времени.After that, periodically close the external electrical circuit. Measurements E.D.S. performed with the load disconnected, and voltage measurements with the included. In terms of eds. and the voltages calculate the electrical resistance of the internal circuit at each time point.
