Early Age Shrinkage Behavior of Triple Blend Concrete
The early age shrinkage is responsible for the early age cracking of concrete. It is very critical for durability of concrete. The change in volume of concrete due to evaporation of water or dehydration process is known as shrinkage. To reduce the early age shrinkage utilized the supplementary cementitious material (SCM) in concrete. In present research industrial and agricultural waste byprodu...
متن کاملEffect Of Water/Cement Ratio And Curing Temperature On Early-Age Shrinkage And Self-Induced Stresses Of High Performance Concrete
This paper presents the results of an experimental study dealing with the influence of water/cement (w/c) ratio and curing temperature on the autogenous deformations and self-induced stresses in early-age concrete. Two concrete mixes, w/c ratio 0.33 and 0.37, were cured isothermally at 10, 20, 30 and 40°C. The linear deformations of a free specimen and the self-induced stresses of a fully restr...
متن کاملGeochemical Evaluation of Geopressued Geothermal Wellbore Cement
Geopressured reservoirs can serve as ample source of geothermal energy with temperatures as high as 140 0C. Salinities are typically high in these reservoirs due to the dissolution of surrounding salt domes. Cement retrogression can occur under these geopressured geothermal conditions resulting from calcium silicate hydrate [3CaO2SiO23H2O] phase in hydrated cement converting to alpha dicalciu...
متن کاملInfluence 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 Cement-Based Materials: II. Influence of Water-to-Cement Ratio
The influence of water-to-cement mass ratio (w/c) on early-age properties of cementbased materials is investigated using a variety of experimental techniques. Properties that are critical to the early-age performance of these materials are tested, including heat release, semiadiabatic temperature, setting time, autogenous deformation, and strength development. Measurements of these properties u...
