Influence of lithium salt on the performance of

2021-3-13  This work explores the effect of lithium salt on the properties of calcium sulfoaluminate (CSA) cements where different proportions of gypsum are added. Experiments comprising hydration heat release, setting time, mechanical strength and hydration products are studied. The results showed that the addition of Li2CO3 significantly accelerates the early hydration and decreases the setting time of ...

Evaluation of Engineering Properties of Calcium ...

Calcium sulfoaluminate (CSA) cement has recently gained increased attention due to its lower amount of CO2 emissions, as compared to that of the ordinary Portland cement (OPC). This paper evaluates the impact of different types of fibers on the engineering features of CSA-based concretes at different water-cement ratios of 0.35 and 0.28. In this study, metallic fibers including double hooked ...

Green Cement: Definition, Types, Advantages, and

Calcium Sulfoaluminate Cement . The calcium sulfoaluminate cement is produced of a kiln that requires a temperature of 1232.2C (2250F) rather than 1426.6 (2500F) of conventional cement. As a result, less CO2 would be released into the atmosphere. The calcium sulfoaluminate cement sets rapidly; gain 28-day strength of conventional concrete in 24 ...

Influence of Nano-SiO2 and Nano-TiO2 on Early

Calcium sulfoaluminate (CSA) cements were currently receiving a lot of attention because their manufacture produced less CO2 than ordinary Portland cement (OPC). However, it was essential to understand all parameters which might affect the hydration process. This work dealt with the effect of two nanostructured materials, such as nanoSiO2 (NS) and nanoTiO2 (NT), on the properties of CSA
