For more than a century, several inclusions have been mixed with Portland cement-nowadays the most-consumed construction material worldwide-to improve both the strength and durability required for construction. The present paper describes the different families of inclusions that can be combined with cement matrix and reviews the achievements reported to date regarding mechanical performance, a...

PURPOSE Clinical, radiological and histological evaluation of root perforations treated with mineral trioxide aggregate (MTA) or Portland cements, and calcium sulfate barrier. METHODS One molar and 11 premolar teeth of a male mongrel dog received endodontic treatment and furcations were perforated with a high-speed round bur and treated with a calcium sulfate barrier. MTA, Portland cement typ...

This paper deals with the study of Nanotechnology experimentation in Civil Engineering which includes the development, advantages and limitations of Nano concreting technologies. For reducing carbon emission during cement manufacturing fly ash is used as a replacement in ordinary Portland cement which is termed as Portland pozzolana cement(PPC), this inclusion relatively increases the workabili...

Due to economical and environmental issues, utilization of mineral wastes, e.g. iron ore mine tailing (IOMT), as road materials can be recommended as a sustainable alternative. In the present study, mechanical properties, as well as resistance to freezing and thawing cycles (F-T) of low plasticity clay soil stabilized with different percentages of Portland cement (0, 6, 9, 12 and 15%) and diffe...

The cementitious materials under consideration by Caltrans for rigid pavement construction may be classified into four categories: Portland cements and blends, calcium aluminate cements and blends, calcium sulfoaluminate cements, and fly ash-based cements. With the exception of Portland cements, most of the cementitious materials under consideration have not been extensively used for pavement c...

introduction: the aim of this study was to compare the cytotoxicity of proroot mta (pmta), root mta (rmta) and portland cement (pc) on human gingival fibroblasts (hgfs). materials and methods: the extracts of the test materials were placed close to human gingival fibroblasts (hgfs) within 96-well plates. cellular viability was assessed using mtt assay in different intervals (freshly mixed, 4, 2...

INTRODUCTION The setting times of commercial mineral trioxide aggregate (MTA) and Portland cements vary. It was hypothesized that much of this variation was caused by differences in particle size distribution. METHODS Two gram samples from 11 MTA-type cements were analyzed by laser diffraction to determine their particle size distributions characterized by their percentile equivalent diameter...
