Standard and alternative methods of determination of the strength of brick at inspection of buildings and structures
Methods of determining the strength of bricks at inspection of stone buildings and structures are considered in this article. Their advantages and disadvantages are described. Results of determination of the strength of a brick by various methods on real objects are presented. The assessment of dispersion of strength of a brick tested by a standard method and cylindrical samples drilled from masonry is executed. Results of experiments on brick test by various methods, executed on the samples selected from structures and acquired at brick factory, are presented.The connection between the strength of samples, coring from stretcher face of bricks, and strength, received by a standard method, is revealed as a result of research of a modern brick.
