متن کاملIn vitro Bioactivity Assessment of Novel Composites Based on Calcium Aluminate Cement
The effect of pseudowollastonite (Pw) additions on the in vitro bioactivity and compressive strength of composites based on calcium aluminate cement (CAC) was studied. Composites were prepared by mixing calcium aluminate clinker with pseudowollastonite (5 and 10 wt%) at a w/c ratio of 0.4 (0.015M LiCl aqueous solution). In order to assess the in vitro bioactivity and compressive strength, compo...
متن کاملSolidification/stabilization of toxic metals in calcium aluminate cement matrices.
The ability of calcium aluminate cement (CAC) to encapsulate toxic metals (Pb, Zn and Cu) was assessed under two curing conditions. Changes in the consistency and in the setting time were found upon the addition of the nitrates of the target metals. Both Pb and Cu caused a delay in CAC hydration, while Zn accelerated the stiffening of the mortar. Compressive strengths of the metal-doped mortars...
متن کاملPoly(carboxylate ether)-based superplasticizer achieves workability retention in calcium aluminate cement
Calcium aluminate cement (CAC) suffers from loss of workability in less than an hour (~15 minutes) after first touch of water. Current superplasticizers that are utilized to modify the viscosity of cement admixtures are designed to target ordinary Portland cement (OPC). The high affinity between these superplasticizers and cement particles were found to be detrimental in CAC systems. Utilizatio...
متن کاملShear bond strength of novel calcium aluminate-based cement (EndoBinder) to root dentine
OBJECTIVE To evaluate the shear bond strength of a novel calcium aluminate-based cement, EndoBinder (EB), to dentine in comparison with Grey and White Mineral Trioxide Aggregate (MTA). MATERIALS AND METHODS Root canal hemi-sections obtained from 30 extracted molar teeth were embedded in self-polymerized acrylic resin and were grounded wet in order to obtain a flat dentine surface. Next, the r...
