Análise do desempenho de três tipos de cimento no concreto de pós-reativos

Abstract

In search of a concrete that is stronger and more durable with the advancement of technology additives and additions to the concrete was found concrete post-reactive (CPR), which is composed of a high capacity of resistance and ductility, virtually waterproof and very promising because of its performance. Discovered in France during the 90s it has great chances to be the most used cement in the future more concrete in large structures. By being self-compacting, the new material dispenses vibration equipment and it is excellent in both the molding of pre-made structures and the restoration of deteriorated since it easily adheres to other concrete. This study aimed to verify the performance variations in test results of tensile and compressive strength of the CPR, the use of different types of cements available in Brazil. Were tested cements CPII-Z CPIV and CPV ARI and broken aged 1, 3, 7 and 28 days of curing submerged in 194 F for at least seven days, followed by room temperature (69,8 F) until the 28 days. Noting that the different types of cement concrete strength interfere with post-reactive.
