Изобретение относитс  к промышленности строительных материалов и может быть использовано при испытании строительных материалов, в частности  чеистого бетона.The invention relates to the building materials industry and can be used in testing building materials, in particular cellular concrete.

Известен способ испытани  бетонных образцов путем приложени  к ним нагружающих , усилий 1 .There is a known method for testing concrete samples by applying a loading force 1 to them.

Недостатком этого способа  вл етс  необходимость испытани  большого количества образцов дл  получени  требуемой точности .The disadvantage of this method is the need to test a large number of samples to obtain the required accuracy.

Наиболее близким из известных к предложенному  вл етс  способ испытани  бетонного образца, например на изгиб, заклю чающийс  в приложении к образцу нагрузки и доведении его до разрушени  l2 ,The closest known to the proposed method is a test of a concrete sample, such as a bend, which is applied to the sample load and bring it to fracture l2,

Недостатком указанного способа  вл етс  большой разброс результатов и невозможность получени  значени  прочности бездефектного материала.The disadvantage of this method is the large scatter of results and the impossibility of obtaining the strength value of the defect-free material.

Целью изобретени   вл етс  повышение точности определени  прочностных характеристик бетона.The aim of the invention is to improve the accuracy of determining the strength characteristics of concrete.

Поставленна  цель достигаетс  тем, что наг-ружение и разрушение образца производ т многократно, причем после каждого разрушени  образец склеивают по поверхности разлома.This goal is achieved by the fact that the loading and destruction of the specimen is performed multiple times, and after each fracture the specimen is glued along the fracture surface.

Предлагаемым способом, можно испытывать один и тот же образец до 10 - 20 раз. С каждым испытанием показатели прочности делаю-тс  все более близкими, они асимптотически приближаютс  к показателю прочности данного материала, лищенного случайных дефектов. Получение экспериментальных данных по прочности такой условно бездефектной стуктуры материала имеет большое значение, так как позвол ет более правильно сравнивать материал с друпгми аналогичными материалами , а также более точно вы вл ть различные зависимости, например , зависимость прочности данного материала от его пористости и т.п.The proposed method can test the same sample up to 10 - 20 times. With each test, the strength indicators are made closer and closer, they asymptotically approach the strength index of a given material, free of random defects. Obtaining experimental data on the strength of such a conditionally defect-free material structure is of great importance, since it allows comparing the material with other similar materials more correctly, and also more accurately reveals various dependencies, for example, the dependence of the strength of a given material on its porosity, etc. .

Преимуществом предлагаемого способа  вл етс  то, что дл  получени  той же точности испытани  требуетс  в 10-20 раз меньше образцов, а.кроме того, сушествев но повышаетс  точность испытаний, так какThe advantage of the proposed method is that in order to obtain the same accuracy of testing, 10-20 times smaller samples are required, and, in addition, it does exist, but the accuracy of the tests increases, since

при проведении одинакового количества VLCпытаний , разброс данных при предлагаемом способе в несколько раз меньше, чем. при известных.when carrying out the same number of VLC tests, the scatter of data with the proposed method is several times less than. with known.
