Abstract

The objective of this research is to evaluate the relationship between the type of capping of cylindrical concrete specimens and their respective final value of compressive strength, so that to determine compliance by the method used . We studied three possible methods for making the faces of the cylinder, the first involves placing a mixture of gypsum-cement hardened specimens, the second is to place a mixture of Portland cement made with fresh specimens and the latter refers to the preparation of hardened faces of the specimens by the respective polishing. As a main point of comparison have cylinders with polished faces, considered the most representative, since the failure load is applied directly to the specimen, then analyzed the results of compression of the other elements. As a final result of the research, there is not a significant difference in the value of unconfined compressive strength, therefore the three methods for preparing the faces of the cylinder are acceptable.
