Summary: The study demonstrates that CO2 emissions during clinker production of cement can be reduced by utilizing a metathesis reaction at room temperature in ball-mills. This method involves forming aNaSiCC, an amorphous intermediate, by mechanochemical activation of CaCO3 and Na2SiO3. It helps understand the interplay between thermodynamics and kinetics in complex reactions of alkali-activated binders and for CaCO3 crystallization in industrial and geochemical settings.

Summary: This article evaluates the shrinkage and strength gain in alkali-activated low-calcium fly ash (AAF) geopolymers. The AAF mixtures, designed for strength, were evaluated for various compositional variables, including the water and sodium contents. The strength gain in the AAF mixture is attributed to the formation of sodium aluminosilicate (NASH) gel under accelerated curing conditions. Moisture loss during drying leads to a decrease in the NASH gel content, while its composition remains unchanged. The study suggests that AAF mixtures with lower water content and prevention of moisture loss are suitable for precast applications.

Summary: The incorporation of graphene and its derivatives into cement for electrically conductive composites is currently being extensively studied for their potential use as smart materials. However, there is a lack of theoretical models to predict the electrical conductivity and piezoresistive properties of these composites, considering the effects of pores and graphene ripples. To address this gap, this paper proposes a two-step micromechanical modelling to predict the electrical conductivity and strain-sensing response of graphene nanoplatelet reinforced cement composites (GNPRCCs), taking into account the effects of pores and graphene ripples.
