Experimental Modeling of the Compressive Behavior and Capillary Absorption of Mortars Based on Tuff of MEKLA
Abstract
Mineral additions are currently part of the most recent developments in the field of Civil
Engineering, as their use improves the mechanical properties and durability of cementitious materials. On the
other hand, their uses aim to reduce the consumption of cement (reduction of CO2), contributing in a simple and
economical way to solving problems related to the environment. This study aims to study the mechanical
behavior of mortars based on tuff of MEKLA as a substitute for cement, using the following percentages: 5, 10,
15, 20, 25 and 30%. All the compositions were manufactured with a water to cement W/C= 0.5 ratio. The
compressive strengths were determined at different ages: 7, 14, 28 and 90 days. We also carried out capillary
absorption tests on the different samples studied. The results showed that all 28-day-old tuff samples had
strengths greater than 30 MPa and those 90 days-old presented strengths greater than 40 MPa. Regarding the
capillary absorption tests, mortars with 5% and 10% tuff aged 28 days showed lower capillary absorption
coefficients than the control mortar.
