INVESTIGATING THE LINEAR EXPANSION, SET, AND STRENGTH BEHAVIORS OF THE BINARY MIXTURE PORTLAND CEMENT CLINKER-GYPSUM
Abstract: The linear expansion, early-age compressive strength and setting times of the binary mixtures of gypsum and Portland cement clinkers of relatively low C3A-contents were investigated. For this reason, type 1, 2, and 5 of Portland cement-clinkers were selected and a number of binary mixtures were designed. At relatively lower percentages of gypsum (about 5%), the early strength behavior...
متن کاملMTA versus Portland cement: review of literature
Introduction: Both Mineral Trioxide Aggregate (MTA) and Portland cement (PC) have been highlighted because of their favorable biological properties, with extensive applications in Endodontics, including the possibility of using into root canal filling. Objective: This article reviews literature related to MTA and PC comparing their physical, chemical and biological properties, as well as their ...

متن کاملDrying Shrinkage Mechanisms in Portland Cement Paste
The shrinkage mechanisms of portland cement paste were investigated from shrinkage, weight loss, and pore structure measurements using nitrogen sorption and mercury intrusion porosimetry (MIP). Thin samples (2.3 mm) of well-hydrated (165 d) pastes of 0.4 and 0.6 water-to-cement (W/C) ratios were dried directly from saturated surface dry state to 75%, SO%, 11%, and 0% relative humidity (rh). Fro...
متن کاملIce nucleation by ordinary Portland cement
Portland cement was studied for its nucleating ability by the freezing behaviour exhibited of drops produced from aqueous suspension of Portland cement vis-a-vis of drops produced from suspensions of AgI, 2AgI.NaI and PbI,. I t is revealing to note that, at temperature colder than 5"C, Portland cement is as potent an ice nucleant as is either 2AgIaNaI or PbI,. At temperatures approaching 5"C, P...
