The Effect of Sulfate on the Electrical Properties of Cement Pastes
Exposure conditions significantly affect the resistance of cement to sulfate attack. This article investigates the effect of sulfate on electrical conductivity of ordinary Portland cement (OPC). Cement paste specimens were prepared according to water/cement (W/C) ratio equal 0.25 either free of sodium sulfate or its addition with concentrations of 5000ppm, 10000ppm and 15000ppm by weight. This ...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
15 صفحه اولInfluence of alkalis on porosity percolation in hydrating cement pastes
Loss-on-ignition (LOI) measurements and low temperature calorimetry (LTC) are used to study the properties of hydrating cement pastes with various quantities of alkalis. In addition to the well-known acceleration of early age hydration and ‘‘retardation’’ of later age hydration, the alkalis are observed to have a significant effect on the percolation of the porosity in the hydrating systems, as...
متن کاملInfluence of Carbon Nanotube Clustering on Mechanical and Electrical Properties of Cement Pastes
Given the continued challenge of dispersion, for practical purposes, it is of interest to evaluate the impact of multi-walled carbon nanotubes (MWCNTs) at different states of clustering on the eventual performance properties of cement paste. This study evaluated the clustering of MWCNTs and the resultant effect on the mechanical and electrical properties when incorporated into cement paste. Cem...
