Determination of the brick brand using the transition coefficient
Abstract
Ceramic brick is one of the first places among other building materials. Accordingly, in order to guarantee the reliability of the work of brick structures, as well as to improve their strength characteristics, it is necessary to conduct a study of bricks.
Traditional methods and means of brick testing were used in the research process.
The technique of conducting experiments provided:
- Classical test.
The mark of bricks and stones is established by the results of their test for compressive strength and bending for all types of bricks produced in accordance with DSTU B В.2.7-248: 2011.
- Tests by simplified methods.
The simplified test method is based on the classical method according to DSTU.B. B.2.7-248: 2011.
Testing process.
The tests were carried out in accordance with the requirements.
Research results
A chart of indicators of the difference of the transition coefficients was developed, as well as protocols for testing the bricks.
Conclusions and evaluation of the results obtained
Experimentally examining three methods of brick destruction, determined that the most effective and accurate way is to study samples with an intermediate rubber plate.
The advantages of this method are the less time spent on the preparation of samples and increased efficiency of the use of technical and material resources, namely the technical rubber woven plate.
When calculating the coefficients of the transition from the compressive strength of the conventional method to the compressive strength of the simplified method, we found that this coefficient of test samples is affected by the method of connection, namely the type of material used in the experiment. In the example of cement-sand compound, we can observe that the coefficient is influenced by the type and quality of sand and the water-cement ratio.
Therefore, it follows from the results the study that the conversion factor greatly simplifies the definition of the brand of brick.
