water.The process of producing a monolithic concrete structure on site is constructed out under different climatic conditions, which can often be unsuitable for setting and hardening of concrete. The necessary conditions for setting and hardening of concrete are ensured by various ways of its curing....
water then the evaporation limit needs to be set lower-more like 0.05 to 0.1 pounds per square foot per hour. The best approach for decorative concrete is to try to alter conditions so you don't need to do initial curing: block the wind, keep the sun off the concrete, get cooler ...
Water permeation into concrete causes various types of deterioration in concrete structures such as rebar corrosion, frost damage, ASR, etc.; however, the evaluation of the water permeation rate is difficult. This paper proposes a simple equation to evaluate the water permeation rate into concrete,...
To delay the progress of degradation such as neutralization and salt damage by densifying surface layer properties of concrete and cement mortar, suppressing water content dissipation of concrete and cement mortar, and reducing dry shrinkage.SOLUTION: The wet curing water of concrete and cement mortar...
For the evaluation of the effectiveness of curing of concrete in the field a non-destructive, rapid test method has been developed. With this method air permeability of concrete surface layers is measured within a period of about 10 minutes, expressed in terms of a permeability index. Laboratory...
To study the effectiveness of adding PFA or CSF in reducing the heat generation of curing concrete,a series of concrete mixes with water/cement ratios ranging from 0.24 to 0.40 and different amounts of PFA or CSF added were tested for their heat generation. The results illustrated that the ...
This paper discusses internal curing of high-strength concrete using presoaked lightweight aggregate (LWA). The effect of internal curing depends directly on the distance over which the internal curing water can travel. The effectiveness of internal curing is a function of the ratio between the ...
The results reveal, the water absorption and retentivity are superior for non-woven compared to woven of same fabric density by its three-dimensional structure and space ratio. The concrete strength, cured with non-woven is 2.15 N/mm2 and it is higher than the woven of same fabric density ...

The effect of limewater on flexural strength and water permeability of TiO2 nanoparticles binary blended concrete has been investigated. TiO2 nanoparticles with partial replacement of cement by 0.5, 0, 5 and 2.0 weight percent have been used as reinforcement. Curing of the specimens has been carried...
