The present work provides a special contribution for assessment of the compressive strength of the concrete through a low-cost test. Here, an alternative pull out test is presented and an experimental campaign was carried out aiming the demonstrate the applicability of this novel methodology. Three different classes of concrete were performed, namely C20 (20 MPa), C25 (25 MPa) and C40 (40 MPa), each one with two variations of the reinforcement rebar diameter, that were 10 and 16 mm. In addition, references samples also were casted and submitted to compressive strength test by NBR 5739. The results found confirmed the applicability of the novel methodology for obtainment compressive strength of concrete.
IntroduçãoA infância idealizada é o momento mágico da vida, com todas as fantasias, descobertas e alegrias que se vive neste período. Contudo, ao reconhecer as crianças ao nosso redor, podese constatar que as desigualdades sociais impedem que algumas destas tenham uma infância assistida. Frota (2007), ao citar Fontes (2005), revela que as desigualdades na infância das crianças brasileiras vêm de longa dada, ressaltando a história da infância no Brasil confundindo-se com a história do preconceito e do abandono; afirmando que desde os primórdios da sociedade brasileira houve diferenciação entre as crianças, de acordo com sua classe social, com direitos e lugares que ocupavam no tecido social.
