Avaliação comparativa do comportamento mecânico de concretos leves com ar incorporado

Or the present study aims to discuss or effect two incorporators of non-mechanical behavior and durability of non-local molded concrete elements. The experiment was developed with a set of samples with 4 different specific masses (1500kg / m³, 1700kg / m³, 2000kg / m³ and 2300kg / m³) and 3 water / food ratios (0.63 - 1: 5, 0.50 - 1: 4, 0.43 - 1: 3), tests for the determination of compressive strength, water absorption, depth ratio and depth of carbonation. The results obtained are not expressive, they do not behave as indicators of armor protection (water absorption and carbonation) or confirm the need to use additional water softeners for the structure (protective paints, stainless steel bars), due to premature loss. Gives durability to a lifelong life.
