“…Moreover, this calcined clay can be used as a cement clinker substitute up to fifty percent as a pozzolana [22]. Substituting 50% of clinker with limestone and calcined clay (1:2 wt ratios) promotes the possibility of developing a novel blended cement of economic and sustainable performance while maintaining similar strength properties of OPC [24,30].…”

“…Thirdly, aluminates from calcined clay can react with CaCo3 and CH generating additional Hc [10]. The idea behind incorporating limestone with calcined clay is that limestone promotes clinker hydration, facilitates hydrate nucleation by providing surface area, and controls hydration reactions in the presence of aluminates [30]. The quantity of reacted limestone is mainly related to the purity of the aluminate source.…”

Recently, sustainable green binders became mandatory for the construction industry. The process of cement production is responsible for a considerable portion of CO2 causing global warming. Clinker substitution using available by-products is one of the promising strategies to cut down the CO2 emissions of the cement industry. Yet, it is challenging to limit the emission of CO2 without negatively affecting the strength and durability of the proposed concrete. One of the proposed green binders is Limestone-Calcined Clay cement (LC3). The newly developed LC3 binder integrates the advantages of incorporating available cement replacement materials - clay and limestone – and attaining adequate mechanical, physical, and durability performance. In this paper, an intensive review of previous research in LC3-based construction materials including nanomodification, fiber reinforcement, and durability enhancement is presented in details, aiming to highlight the points that lack investigation and the recommended future work.

“…Thus, the search for alternatives for the manufacture of alternative binders that involve partial or total replacement of OPC has become a worldwide trend. [2]. Different alternatives have been proposed, including alkali-activated cements from raw materials rich in aluminosilicates mixed with an alkaline solution composed of silicate and alkali metal hydroxide, where the most commonly used are silicate and sodium hydroxide.…”

Ceramics tile wastes (CWs) were mechanically conditioned for the preparation of alkali-activated hybrid-cements from CW (90 wt.%) and Portland cement (10 wt.%) mixtures using sodium silicate (SS) + NaOH as alkaline activators. Molar ratios of SiO2/Al2O3 (6.3 to 7.7) and Na2O/SiO2 (0.07 to 0.16) were used. The cements were prepared at room temperature (25 °C) and characterized by mechanical and physical properties and microstructure. The optimized cement was used for the preparation of novel photoactivated composite materials by incorporating 5 and 10 wt.% TiO2 (Ti) and ZnO (Z) nanoparticles, and its self-cleaning and bactericidal properties were evaluated by means of the degradation of rhodamine-B (Rh-B) and the growth inhibition of Klebsiella pneumoniae and Pseudomonas aeruginosa bacteria. The results of this study showed that the 100SS-5Z and 50SS:50G-10Ti cements have an effective photocatalytic activity for Rh-B degradation of 98.4% and 76.4%, respectively, after 24 h. Additionally, the 100SS-5Z and 50SS:50G-10Ti cement pastes and their respective mortars were effective in inhibiting the growth of Pseudomonas Aeruginosa and Klebsiella pneumoniae bacterial strains, evidenced by the formation of bacterial inhibition halos around the sample discs. Finally, these results are novel, and open the possibility of using constructions and demolition tile waste in high proportions for the elaboration of new rendering mortar with innovative properties.
