Influence of Shrinkage-Reducing Admixtures on Early-Age Properties of Cement Pastes
Because most shrinkage-reducing admixtures (SRAs) significantly reduce the surface tension of a cement paste pore solution, they will naturally influence all physical properties and processes that are dependent in some way on surface tension. Such properties include internal relative humidity, capillary stresses, and freezing point depression, all via the Kelvin equation and its variants (Kelvi...
متن کاملEarly Age Properties of Portland Cement Pastes Investigated with Ultrasonic Shear Waves and Numerical Simulation
In this paper, the correlation of reflection loss measured by an ultrasonic shear wave reflection method and the microstructure in cement-based material is investigated. Three cement pastes (Portland cement type I) with different water-cement ratios (0.35, 0.50 and 0.60) cured at 25 °C were examined. The ultrasonic shear wave reflection factor (WRF) was measured by the wave reflection technique...
متن کاملCuring with Shrinkage-Reducing Admixtures Beyond drying shrinkage reduction
Shrinkage of concrete, along with the cracking that often accompanies it, has been a continual concern of the concrete construction community.1,2 In the past 20 years or so, numerous shrinkage-reducing admixtures (SRAs) have been developed with the goal of reducing drying shrinkage and delaying or preventing cracking.2-6 Most SRAs function by reducing the surface tension of the pore solution in...
متن کاملEffect of Admixtures on the Yield Stresses of Cement Pastes under High Hydrostatic Pressures
When cement-based materials are transported at a construction site, they undergo high pressures during the pumping process. The rheological properties of the materials under such high pressures are unknown, and estimating the workability of the materials after pumping is a complex problem. Among various influential factors on the rheology of concrete, this study investigated the effect of miner...
متن کاملInfluence 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...
