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...
متن کاملEffect of Graphene Oxide Nanoparticles Addition on Mechanical and Biological Properties of Calcium Phosphate Cement
In the present study, we have evaluated the effects of graphene oxide (GO) addition on the physical-mechanical-biological properties of calcium phosphate cement (CPC). The in vitro cellular responses of MG63 and in vivo tissue responses after the implantation of CPC/GO in parietal bone defects of wistar rats were also investigated. The brushite calcium phosphate cements were prepared by mixi...
متن کاملInfluence of Microencapsulated Phase Change Material (PCM) Addition on (Micro) Mechanical Properties of Cement Paste
Excessive cracking can be a serious durability problem for reinforced concrete structures. In recent years, addition of microencapsulated phase change materials (PCMs) to concrete has been proposed as a possible solution to crack formation related to temperature gradients. However, the addition of PCM microcapsules to cementitious materials can have some drawbacks, mainly related to strength re...
متن کاملEffects of High Temperature on Carbonated Calcium Silicate Cement (CSC) and Ordinary Portland Cement (OPC) Paste
This paper presents a comparative study on the effects of high temperature (~500°C) on carbonated calcium silicate-based cement (CSC), hydrated ordinary Portland cement (OPC), and hydrated OPC with 20% fly ash (FA) paste samples. The CSC is primarily composed of calcium–silicate minerals with different calcium to silica atomic ratios, such as wollastonite, rankinite, and pseudowollastonite. The...
متن کاملDecalcification shrinkage of cement paste
Decalcification of cement paste in concrete is associated with several modes of chemical degradation including leaching, carbonation and sulfate attack. The primary aim of the current study was to investigate the effects of decalcification under saturated conditions on the dimensional stability of cement paste. Thin (0.8 mm) specimens of tricalcium silicate (C3S) paste, white portland cement (W...
