Abstract
The following information is about the results on experimental tests of a mortar containing fly ash used on roofing application. These results are based on compressive strength, air permeability and specific gravity. Physical and chemical characterization for the fly ash produced is not evaluated this time, but it will in the future. The main purpose of this research is to deal with a common rainwater leakage problem of concrete roofs in Puerto Rico. With this document, Polytechnic University of Puerto Rico evaluated the suitability of several proportions mixtures in a mortar containing fly ash to be used as a topping to prevent water leakages in roofs. It contains cement, water, and aggregate. The fly ash tested is nearly a Class C because it exceeds the maximum allowed for Sulfur Trioxide. The utilization of fly ash concrete mixtures helps to reduce the environmental impact due to the use of aggregates from natural resources like rivers. Key Terms - air permeability, chemical characterization, fly ash, specific gravity.
