Strength Properties of Concrete Having Marble Dust Powder, Calcium Hydroxide and Sodium Silicate

A Study on Strength Properties of Geopolymer Concrete with Addition of G.G.B.S

–Flyash based geopolymer concrete is introduced in 1979 by Davidovits to reduce the use of OPC in concrete. Geopolymer is an inorganic alumino-hydroxide polymer synthesized form predominantly silicon and aluminum materials of geological origin and by product materials such as flyash (with low calcium). In this paper an attempt is made to study strength properties of geopolymer concrete using lo...

Effects of calcium hydroxide addition on the physical and chemical properties of a calcium silicate-based sealer

UNLABELLED Recently, various calcium silicate-based sealers have been introduced for use in root canal filling. The MTA Fillapex is one of these sealers, but some of its physicochemical properties are not in accordance with the ISO requirements. OBJECTIVE The aim of this study was to evaluate the flowability, pH level and calcium release of pure MTA Fillapex (MTAF) or containing 5% (MTAF5) or...

Center for By-Products Utilization CHARACTERIZATION OF MARBLE POWDER FOR ITS USE IN MORTAR AND CONCRETE

Comparative Evaluation of the Cytotoxicity of Two Materials: Calcium Hydroxide Powder, Calcium Hydroxide Reinforced with Chlorhexidine onL929 Fibroblasts by MTT Assay

Background&Aims: Themajor objective of root canal treatment is to disinfect the entire root canal system, which requires that all contents of the root canal system be eliminated as possible sources of infection. This goal may be accomplished using mechanical instrumentation and chemical irrigation. To reduce or eliminate bacteria various irrigation solutions have been applied during the treatme...

Ab-initio study of the structural and phononic properties sodium hydroxide (Research Article)

In this work the structural phase stability and phononic properties of sodium hydroxide compound have been reported. The calculations have been performed using the pseudo potential method with plane wave based on density functional theory (DFT). Local density approximation (LDA) and generalized gradient approximation (GGA) have been used for modeling the exchange-correlation potential. Negative...
