A study of the rheological behaviour of eco-friendly mortar made with metakaolin and marble powder at various ambient temperatures
The main goal of this research is to study the effect of temperature on the rheological properties, namely, slump, flow time, yield stress and plastic viscosity as well as the compressive strength of concrete equivalent-mortars (CEM). For this purpose, eleven mixtures of CEM were designed from their corresponding concrete by replacing a part of cement with metakaolin (MK) and marble powder (MP) at different substitution levels ranging from 5 to 50% in binary and ternary systems with water-to-binder ratio of 0.4. The rheological properties of CEM were evaluated at different temperatures ranging from 10 to 50 °C. While, the compressive strength of CEM made with MK was determined at 28 days of curing in a standard environment. The obtained results revealed that the increase of temperature from 10 to 40 °C decreased the slump and increased the rheological properties as well as the flow time of all CEM. However, at temperature of 50 °C, the slump flow of all CEM increases while the flow times decreases.
