Enhancing Mortar Properties through Thermoactivated Recycled Concrete Cement
The effects of thermoactivated recycled concrete cement (TARC) on mortar as a partial replacement for cement was examined. TARC is derived from concrete waste through a series of processes. Different mortar mixtures were tested, ranging from 0% to 50% TARC in 10% increments. A comprehensive range of...

| description | The effects of thermoactivated recycled concrete cement (TARC) on mortar as a partial replacement for cement was examined. TARC is derived from concrete waste through a series of processes. Different mortar mixtures were tested, ranging from 0% to 50% TARC in 10% increments. A comprehensive range of tests was conducted to assess the properties of the mortar, including fresh, mechanical, microstructure, and durability evaluations. The fresh test indicated that the incorporation of TARC impacted the flow of mortar, leading to reduced workability as the percentage of replacement increased. Regarding mechanical performance, using 20% TARC resulted in improved compressive strength, bulk density, and ultrasonic pulse velocity (UPV). Microstructural analysis using thermogravimetry, scanning electron microscopy, and Fourier transform infrared spectroscopy (FTIR) revealed that the TARC mix exhibited advantageous thermal properties, enhanced FTIR spectra, and a denser microstructure, thereby enhancing the durability of the mortar. Overall, substituting OPC with TARC significantly reduces the carbon footprint associated with cement production, promoting sustainability and contributing to a circular economy in the construction industry. |
