Description
Изобретение относитс к области механических испытаний материалов, в частности к способа.м испытани образца строительного материала на сжатие.The invention relates to the field of mechanical testing of materials, in particular, to a method of testing a sample of a building material in compression.
Известен способ испытани образца строительного материала на сжатие, заключающийс в том, что образец кубической формы устанавливают одной из граней на опорную плиту, а к противоположной грани образца прикладывают сжимающую нагрузку 1.A known method for testing a sample of a building material in compression is that a sample of a cubic shape is placed on one of the faces on a support plate, and a compressive load 1 is applied to the opposite face of the sample.
Недостатком известного способа вл етс его сложность, котора св зана с использованием испытательной машины на сжатиеThe disadvantage of the known method is its complexity, which is associated with the use of a compression testing machine.
Цель изобретени - упрощение испытани .The purpose of the invention is to simplify the test.
Цель достигаетс тем, что в качестве опорной плиты используют эталонную пластину , размещенную на опорах, рассто ние между которыми превыщает линейный размер образца, нагрузку прикладывают до разрушени образца или пластины и по результатам разрушени суд т о прочности испытуемого образца.The goal is achieved by using a reference plate placed on supports, the distance between which exceeds the linear size of the sample, the load is applied until the sample or plate is destroyed and the strength of the test sample is determined by the results of the destruction.

Образец 1 кубической формы устанавливают одной из граней на :)та.юинук) n.uicтину 2, размещенную на опорах 3 и 4. рассто ние между которыми превышают линейный размер С образца. К противоположной грани прикладывают нагрузку Р, котора вызывает сжимающие напр жени в образце и изгибающие напр жени в n.iacTiiне . Эталонна пластина разрушаетс ири нагрузке, величина которой зависит от рассто ни -В между опорами 3 и 4. Эта нагрузка выбираетс такой, какую должен гарантированно выдерживать испытуемый строите .тьный .материал. Дли устранени трени Sample 1 of a cubic shape is set by one of the faces on:) ta.yuinuk) n.uictinu 2, placed on supports 3 and 4. The distance between which exceeds the linear dimension C of the sample. A load P is applied to the opposite face, which causes compressive stresses in the sample and bending stresses in n.iacTii not. The reference plate is destroyed by the load, the magnitude of which depends on the distance-B between supports 3 and 4. This load is chosen to be such that the test subject is able to withstand building the material. To eliminate friction
место установки образца па пластине смазываетс парафином. Нагружение образца силой Р производ т надавливанием на образец или приложением весовой нагрузки. При увеличении нагрузки наблюдают за разрушением образца или пластины. Если первым разрушаетс образец, значит он не выдерЖ1шает требуемой нагрузки. Если же первой разру1иаетс пластина, значит образец удовлетвор ет ) прочности. Далее измен ют пролет между опорами 3 и 4 соответственно в сторону увеличени или уменьшени в зависимости от результатов разрушени и провод т испытание вновь дл уточнени интервала, в котором заключена прочность образца.The installation site of the sample on the wafer is smeared with paraffin. The loading of the sample by force P is made by pressing on the sample or by applying a weight load. With increasing load, observe the destruction of the sample or plate. If the specimen is destroyed first, then it does not withstand the required load. If the plate is the first to fail, then the sample satisfies strength. Further, the span between supports 3 and 4 is changed, respectively, in the direction of increase or decrease depending on the results of the fracture, and the test is carried out again to clarify the interval in which the strength of the specimen is contained.
