Physical Behavior of Ternary Portland Cement Mortar Mixtures Incorporating Pozzolan and Filler

摘要

This work shows the results carried out by mixtures of Portland cement mortars with two additions: ash brick ovens (CELU) which acting as pozzolan, and ground expanded perlite (PEM) as filler. The objective of this research is to determine whether by adding a pozzolan and filler mixtures base Portland cement is possible to increase physical and mechanical behavior. There were 3 mixtures: the control and 2 more: one with substitution of 7% CELU, and other with 7% CELU+5% PEM respectively, carrying out tests of normal consistency, setting, fluency, simple compression, indirect tension, ultrasonic pulse velocity and electrical resistivity at the ages of 3, 7, 14, 28 and 120 days. The results were favorable in the mixture that incorporates both materials (CELU+PEM).
