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 کاملEarly-Age Structural and Thermal Performance of GGBS Concrete
A large amount of blast furnace slag is generated in China. Most ground granulated blast furnace slag (GGBS) however ends up in low-grade applications. Blast furnace slag, ground to an appropriate fineness, can be used as a partial replacement of cementitious material in concrete. The potential for using GGBS in structural concrete, e.g. concrete beams and columns is investigated at Xi’an Jiaot...
متن کاملThermal Stresses in the Microwave Heating of Concrete
The significance of compressive thermal stresses generated during microwave heating on concrete surface delamination is investigated analytically in this paper. Microwave energy acts as an internal heating source that causes concrete to heat up. The amount of microwave energy dissipated in concrete depends on microwave frequency, microwave power and the electromagnetic properties of the concret...
متن کاملInterface stresses in concrete bridge deck overlays subjected to differential shrinkage
Concrete overlays on bridge decks are expected to be more durable as compared with the more common asphalt solution. Besides stresses due to traffic load and temperature variations at service, the overlays are exposed to stresses due to long term shrinkage. Of interest is to evaluate the concrete overlay due to the shrinkage induced stresses at the composite interface. Three strategies have bee...
