Description
(5М СПОСОБ ИСПЫТАНИЯ НА РАСТЯЖЕНИЕ(5M STRETCH TEST METHOD
Изобретение относитс к испытани материалов и может быть использовано .при испытании строительных материалов на ползучесть в агрессивных средах . Известен способ испытани на раст жение образцов, преимущественно, строительных материалов, заключающий с в том, что используют цилиндрический образец с зауженной центральной частью, размещают его в цилиндри ческом сосуде, уплотн ют концы образца относительно стенок сосуда и нагружают раст жением путем подачи среды под давлением в полость сосуда 11 . Недостатком известного способа вл етс низка точность при исследовании ползучести материалов в ai рессивных средах, поскольку врем проникновени среды в образец может быть соизмеримо с полным временем затухани ползучести. Цель изобретени - повышение точности испытани при исследовании ползучести материалов в агрессивных средах. Поставленна цель достигаетс тем, что концы образца пропитывают импрегнатом , а гидростатическое давление агрессивной среды выбирают из услови обеспечени фильтрационной проницаемости материала. На чертеже схематично изображено устройство, реализующее предлагаемый способ. Устройство содержит цилиндрический сосуд 1 с крышк ами 2, уплотн ющие манжеты 3 индикаторы дл измерени деформации, зафиксированные относительно корпуса сосуда 1. Способ осуществл етс следующим образом. В цилиндрический образец 5 строительного материала, имеющий зауженную центральную часть, при изготовлении закладывают с его торцов меThe invention relates to the testing of materials and can be used when testing building materials to creep in corrosive environments. A known test method for stretching specimens, mainly building materials, is concluded in using a cylindrical specimen with a narrowed central part, placing it in a cylindrical vessel, compacting the ends of the specimen relative to the vessel walls and loading by stretching by supplying a medium under pressure into the cavity of the vessel 11. The disadvantage of this method is the low accuracy in the study of creep of materials in ai suspended media, since the time of penetration of the medium into the sample can be commensurate with the total creep decay time. The purpose of the invention is to improve the accuracy of testing in the study of creep of materials in aggressive media. The goal is achieved by the fact that the ends of the sample are impregnated with impregnate, and the hydrostatic pressure of the corrosive medium is chosen from the conditions of the permeability of the material. The drawing schematically shows a device that implements the proposed method. The device comprises a cylindrical vessel 1 with lids 2, sealing cuffs 3 indicators for measuring deformation, fixed relative to the vessel body 1. The method is carried out as follows. In a cylindrical sample 5 of a building material, having a narrowed central part, in the manufacture it is laid from its ends
