The objective of this work was to study the partial substitution of the natural (sand) aggregate by ash from sugarcane bagasse (CBC), by mass, in the proportions of 10% and 20% for the preparation of pieces of concrete for interlocking pavement. Firstly, the pilot trait was developed, this one still without the addition of CBC, which served as parameter for comparisons. The properties of the aggregates and the concrete were analyzed through standardized tests of granulometry, specific mass, slump test, compressive strength and water absorption. As for the values of compressive strength, the 10% substitution trait presented the best result of compressive strength, being 15% superior to the pilot trace. As for absorption, an increase in permeability was observed as the addition of CBC increased. Finally, it was concluded that the satisfactory trait in relation to the properties analyzed was the 10% substitution trait. [ABSTRACT FROM AUTHOR]

Os cursos universitários buscam capacitar o aluno de forma que o mesmo, assim que formado, possa ingressar no mercado de trabalho com conhecimentos compatíveis às suas atribuições. Para isso, os conhecimentos teóricos precisam estar associados aos conhecimentos práticos. Vários laboratórios precisam ser disponibilizados para cursos universitários, inclusive para cursos de Arquitetura e Urbanismo e Engenharia Civil, entre eles o canteiro de obras experimental, que insere o aluno no contato direto da obra. No entanto, este ambiente não tem sido implantado com frequência. Desse modo, este artigo visa a analisar sua importância. A metodologia de pesquisa está baseada em análises documentais e projetuais.

University courses seek to train the students so that they can enter the job market with knowledge compatible to their responsibilities. For this, theoretical knowledge must be associated with practical knowledge. Several laboratories need to be made available for university courses, including courses for Architecture and Urbanism and Civil Engineering, including the experimental construction site, which inserts the student in direct contact work. However, this environment has often not been implanted. Thus, this paper has the objetive to analyze its importance. The methodology of this research is based on documentary and projectual analysis.
