In order to ensure that the early and later age compressive strengths meet the requirements of the technical data sheet at a curing temperature of 5°C, the temperature of the dry-blended MS Cable and mixing water should be kept above 21°C. TABLE 1: CURING CONDITIONS OF MS CABLE CUBE SPECIMENS.
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.
The bond strength was increased by steel rebar surface treatment (acetone, water, ozone or sand blasting, with ozone being most effective and acetone being least effective), silica fume and polymer addition to concrete, increase in water/cement ratio of concrete (particularly from 0.45 to 0.50), and decrease in curing age (particularly from 14 ...

In high curing temperature, the concrete with fly ash has higher strength development than that of low temperature regardless of the elapse of age and maturity. Fly ash can have much effect on the strength development of concrete at the condition of mass concrete, hot weather concreting and the concrete products for the steam curing.
Thirty concrete mixes of differing water-binder ratio containing 0, 10, 20, 30, 40 and 50 % laterite as a partial replacement for sand were used to prepare laterized concrete specimens for the study of the effect of nonstandard curing methods on the strength of specimen.
Curing plays an important role on strength development and durability of concrete. Curing takes place immediately after concrete placing and finishing, and involves maintenance of desired moisture and temperature conditions, both at depth and near the surface, for extended periods of time.

With age, the pancreas decreases in overall weight, and some tissue is replaced by scarring (fibrosis). However, these changes do not decrease the ability of the pancreas to produce digestive enzymes and sodium bicarbonate. As the liver and gallbladder age, a number of structural and microscopic changes occur (see Effects of Aging on the Liver).
These findings mirror the number of earners per household in each age group, which went from 1.1 in the under-25 age category to 1.6 in the 35–44 and 45–54 age categories, before declining from 1.3 for the 55–64 age category to .7 and .2 for the 65–74 and 75-and-older categories, respectively.
The experiments were conducted on fly ash based geopolymer concrete by varying the types of curing namely ambient curing and hot curing. The ratio of alkaline liquid to fly ash is fixed as 0.4. For all the samples the rest period was kept as 5 days. For hot curing, the temperature was maintained at 60 o C for 24 hrs in hot air oven. The ...
This study examined the effects of curing temperature and access to moisture on the early age reaction rate of cementitious materials, and methods for quantifying these effects. Apparent activation energy (Ea) relates the effects of temperature on the cement hydration reaction.
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).

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
