We commercialized Reactive Coke Agglomerate (RCA), a cement-bonded pellet to decrease the thermal reserve zone temperature for the reduction of the reducing agent rate of blast furnaces. To achieve a high productivity of supplying RCA to large blast furnaces, a rapid curing process of RCA using steam was investigated. We obtained rapid curing of RCA within 18 h by combining primary curing for 1...

Basturma, a spiced beef product intended to be cooked before consumption, was prepared in three trials by dry-curing intact surface-inoculated (6 log cfu per piece with Salmonella serovars, Escherichia coli O157:H7 and Listeria monocytogenes) beef eye of round subprimals for 21 days at 6.7C, and then rinsing, pressing and drying for 6–8 days at 21–27C. The finished products had percentage water...

The standard method of curing industrial coatings has been accomplished by slow open air drying or somewhat faster gas heated convection air ovens. Electric infrared has also been used for curing paints for certain applications. While enhancing the rate of cure, the energy costs become excessive to operate. The introduction of gas fueled infrared catalytic thermoreactors is changing the way ind...

IR Versus Convection Heating Medium-wavelength electric IR heating is especially wellsuited to the curing and drying of coatings, because these wavelengths correspond well with the absorption bands for water, which most coatings contain. Additionally, since IR heating does not penetrate the surface very deeply and generally only heats the outer surface, it is applicable for drying coated and pr...

OBJECTIVES The purpose of this study was to investigate the effectiveness of multiple decontamination procedures for salivary contamination after curing of a universal adhesive on dentin bond strength according to its etch modes. MATERIALS AND METHODS Forty-two extracted bovine incisors were trimmed by exposing the labial dentin surfaces and embedded in cylindrical molds. A universal adhesive...

This paper summarizes the results of an investigation on carbon dioxide (CO2) sequestration in concrete. Concrete mixtures were not air entrained. Concrete mixtures were made containing Class C fly ash at 0%, 18%, and 35% of total cementitious materials. Effects of three different curing environments on properties of concrete were studied: (1) moist-curing room with 100% relative humidity (RH) ...

Shrinkage of concrete, along with the cracking that often accompanies it, has been a continual concern of the concrete construction community.1,2 In the past 20 years or so, numerous shrinkage-reducing admixtures (SRAs) have been developed with the goal of reducing drying shrinkage and delaying or preventing cracking.2-6 Most SRAs function by reducing the surface tension of the pore solution in...

Objectives It has been reported that the water, solvents, or the primer incorporated into adhesive resins decrease the polymerization, compromise the mechanical properties, reduce the bond strength, and lead to a poor bonding performance of self-etch adhesives. This article evaluated the effect of air-drying and light-curing duration of self-etch adhesives on the micro-shear bond strength betwe...

The introduction of affordable control networks for peanut dryers has made it possible to easily vary the curing temperature based on ambient air conditions. Previous research has used ambient temperature, relative humidity, and humidity ratio as possible control parameters. Peanuts from the same field were cured using four 0.11 m dryers to a moisture content of approximately 0.11 kg kg. Four d...
