Mortar Mix Design for Roofing Applications
Zusammenfassung
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
