Estudo da adição de cinza de folha de bananeira em argamassas

Abstract

Brazil stands out among the world's leading producers of bananas, in 2008 the country held the fourth place with a production of 7.1 million tons in about 514,000 bushels, which is about 94.63 million of tons of ash of banana leaves. This work verifies the behavior of the addition leaf ash of banana in Portland cement mortars. For analysis of the technological tests were made mortar in proportion of 1:3 (cement: sand) and then addition of banana leaf ash in proportions of 5%, 10%, 15%, 20%, 25% and 30%. The results were satisfactory to the physical and mechanical performances, where all additions with leaf ash of banana had higher values than the reference mortar. One can thus conclude that the use leaf ash of banana is technically feasible due to its pozzolanic reaction with Portland cement.
