Development of Eco-Friendly Cement Using a Calcium Sulfoaluminate Expansive Agent Blended with Slag and Silica Fume

نویسندگان

چکیده

This is an experimental study on the development of a low-carbon, eco-friendly cement containing calcium sulfoaluminate expansive agent (CSAe), slag, and silica fume (SF). The to be developed has low water/binder ratio (w/b) 0.5 designed used for structural purposes, with focus its mechanical performance. CSAe, SF were mixed at various mixing ratios. main hydration product slag-based CSAe in experiment was ettringite. Substituting less than 30% showed sufficient level performance; that is, material could as cement. controlled excessive expansion CSAe. However, since slag-CSAe-SF early age (1 d) strength, follow-up research needed improvement.

Effect of Hydrochloric Acid (HCl) on Blended Cement (Fly Ash based) and Silica Fume Blended Cement and their Concretes

This paper presents the effect of Hydrochloric acid (HCl) on Blended Cement (Fly ash based(BC)) and Silica Fume Blended Cement(SFBC) and their concretes. The BC and SFBC and their concretes BCC and SFBCC produced with HCl dosage of 100, 150, 300, 500 and 900 mg/l added in deionised water. In addition to this control specimens were prepared with deionised water (without HCl) for comparison. The ...

Eco-friendly Blocks by Blended Materials

In spite of broad improvements in construction technology, cement is still stayed as binding material for construction purposes. Cement industries are the main sources for the contribution of carbon dioxide (co2) into the atmosphere. So, there is a need to use new materials as binders (green binders) in substitute for cement, which leads to reducing the production of cement. In this study, fly ...

Effect of Calcium Carbonate Fineness on Calcium Sulfoaluminate-Belite Cement

This study investigated the hydration characteristics and strength development of calcium sulfoaluminate-belite (CSAB) cements incorporating calcium carbonate (CC) powders with various particle size distributions and different gypsum amounts. In general, the CSAB hydration was accelerated by the CC powder, but the acceleration and resulting strength improvement were more effective with finer CC...
