Effect of Curing Conditions on the Shrinkage of Ultra High

Abstract. The effect of curing conditions on the early age and long-term shrinkage of ultra high-performance fiber-reinforced concrete (UHPFRC) was systematically studied. The shrinkage of the early age (0–168 h) and long-term age (0–90 d) of UHPFRC material was measured based on three kinds of humidity conditions (dry, sealed, and soaked) and curing temperatures (25°C, 40°C, and 75°C ...

Curing of tobacco

Flue-cured tobacco was originally strung onto tobacco sticks, which were hung from tier-poles in curing barns (Aus: kilns), also traditionally called oasts.These barns have flues which run from externally fed fire boxes, heat-curing the tobacco without exposing it to smoke, slowly raising the temperature over the course of the curing.

Effect of Curing Age on Chloride Diffusion

2018-05-29 · The effect of curing age on chloride diffusion coefficient of recycled aggregate concrete subjected to different compressive stresses was investigated. A compression loading setup was both designed and fabricated. The chloride diffusion coefficients of recycled aggregate concrete under compressive stresses were measured by the rapid chloride ion migration (RCM) method.

Curing of Concrete

water curing increases this figure to 60%, whilst 28 days water curing increases it to 95%. Keeping concrete moist is therefore, a most effective way of increasing its ultimate strength. Concrete that is allowed to dry out quickly also undergoes considerable early age drying shrinkage. Inadequate or insufficient curing is one of main

The Effects of Aging on Recidivism Among Federal Offenders

Curing and Smoking Meats for Home Food Preservation

Curing should not be used to salvage meat that has excessive bacterial growth or spoilage (PHS/FDA 2001). Meat, especially game meat, does not need to be aged, since curing/smoking will act to tenderize it. If aging is desired, age all meats below 40°F.

5. Effects of various casting factors on ITZ thickness and porosity

The effects of casting factors such as curing age, water to binder (w/b) ratio and aggregate content are discussed, and two new formulas are proposed to fit the ITZ thickness and porosity. Results indicate that curing age influences both the ITZ thickness and porosity, while w/b ratio and aggregate content only influence the ITZ porosity.

Effect of Curing Age on High-Strength Concrete at Low

This investigation deals with the effect of curing age on the strength development of high-strength concrete containing silica fume and fly ash and exposed to cold temperatures. Tests were performed on three sets of specimens, having initial curing ages of 1, 14, and 28 days at room temperature.

Transport properties of concrete after drying-wetting

Permeability measured after 105 °C drying was 3 to 25 times higher than that at 21 °C 55% RH (stepwise) and up to 160% higher than at 50 °C. Therefore, drying induced a much larger change in transport property compared to that achieved by varying the w/b (0.35 → 0.5), curing age (3 → 90 days) or addition of SCMs (GGBS, SF).
