  • Compaction of asphalt pavement is one of the important processes to make good quality one. There are many laboratory-compaction methods to simulate field compaction, including Marshall compaction, Hveem compaction, gyratory compaction, and etc. The most common method used to determine the fundamental properties of asphalt mixture for design is Marshall method which is using impact energy. However, there is major difference between field compaction using kneading compaction and Marshall compaction using impact energy. Therefore, the gyratory compactor, which currently is the best to simulate the field compaction, was employed. The fundamental properties of asphalt specimen compacted by gyratory compactor and Marshall compactor were determined using laboratory test. From the tests, slag mixture with carbon black or pyrolyzed carbon black showed better performances, such as, in low susceptibility to temperature, high resistance against water and rutting, and high resilient modulus and indirect tensile strength.

  • A study was conducted on the preparation of Ramyon using composite flours of raked barley (20 or 30%)-wheat(80 or 70%) in commercial plant scale and on the quality evaluation of Ramyon made from those flours. The naked barley(20%)-wheat(80%) flour gave acceptable Ramyon-making characteristics during the continuous Ramyon manufacturing process. The composite flours had a higher water absorption rate in kneading process and oil absorption value of the Ramyon product than those of wheat flour alone. Even though the Ramyon of composite flours showed a little inferior value compared with wheat flour alone in the cooking and texture characteristics, sensory panel scores of Ramyon indicated that the naked barley (20%)-wheat(80%) flour was acceptable in Ramyon.

  • Bread making is based on several simple unit operations, basically kneading, fermentation and baking; however, it is still a quite complex process and bread quality can be strongly affected by minor details. The market of bread production is roughly shared at 50-50 between the industry market and the artisanal market, even though the frontier between these two players is not very easy. Different strategies have been developped by the industry to extend the shelf life of bread or to interrupt the bread making process. Freezing for example has been used form the 50s to extend the shelf life of bakery products. It was first applied to fully baked products and then to frozen dough which appeared as an interesting strategy to interrupt the bread making protocol. This paper presents a review on key issues of the frozen dough technology.

  • The higher the addition rate, the less difference in kneading was found. This is because most of the cases are mixed with vinyl gloves by hand when immediately mixed in the field, so there is no problem of mixing dough according to the amount of addition. The mean increase temperature for 20 minutes was 31.6℃ for Plain, 38.1℃ for Al, 33.7℃ for Cu, and 5~7℃ for Al 20% added sample, 38.1℃ for Al 20% added sample, but 36.6℃ for Al 5% added sample. This suggests that it is possible to improve its own heat transferability by adding metal powder to epoxy adhesives.

  • Various $Cu/SiO_2$ catalysts with copper concentration ranging from 0 to 50wt% were prepared by kneading method for the steam reforming of methanol. These catalysts were calcined at temperatures in the range of $400^{\circ}C{\sim}900^{\circ}C$ and then reduced in a $H_2$ atmosphere in the range of $150^{\circ}C{\sim}350^{\circ}C$. Steam reforming of methanol was carried out at atmospheric pressure over a temperature range of $200^{\circ}C{\sim}400^{\circ}C$, steam/methanol molar ratio of 0.4~1.6 and W/F of 3~25 g.-cat.hr./mol. Characterization of the catalysts was studied using IR, BET and XRD. Using copper nitrate as a precursor for catalysts, pH in the preparation of catalysts had a great effect on the catalytic activity, but pH in the preparation of catalysts, calcination temperature, and reducing temperature in $H_2$ atmosphere had no effect on the product distribution. Optimum copper concentration, calcination temperature and reducing temperature were 40wt%, $700^{\circ}C$ and $300^{\circ}C$, respective)y. Reaction temperature for maximum $H_2$ production was $275^{\circ}C$, and the formation of methane which lowered quantity and quality of $H_2$ would be inhibited below $275^{\circ}C$. $Cu^{\circ}-Cu_2O$ might be active species in $Cu/SiO_2$ catalyst.

  • Kyongdan is a kind of Korean rice cake made from glutinous rice powder. This study attempted to clarify the factors which affect the textural characteristics, and to examine the effects on sensory characteristics and texture of Kyongdan in various soaking time, temperature and volume of adding water in the preparation of Kyongdan. Evaluation was conducted through sensory evaluation and objective evaluation. The degree of gelatinization in various storage time and temperature were evaluated by $\beta$-amylase digestibility. The results were summarized as follows. 1. In preparation, the significant factors were the temperature and volume of water, number of kneading, condition of powder, and the relationships between soaking time and temperature of water and between volume and temperature of water and between volume of water and number of kneading and between volume of water and salt. 2. In sensory evaluation on the various soaking time and temperature and volume of water, the most favorite tendency on the overall quality was at the addition level of hot water of 25% with glutinous rice powder made by soaking for 12 hours. This condition corresponded to the low level of hardness, gumminess, chewiness and the high level of springiness and cohesiveness in comparision with Instron measurement. 3. The degree of gelatinization were decreased rapidly during two days of storage. In storage temperature, Kyongdan which was stored at $0^{\circ}C$, showed the most low level of the degree of gelatinization at the same storage time.

  • The recycling of waste XLPE(crosslinked polyethylene), which is a major source of scraps from high voltage power transmission cables, has been discussed. The waste XLPE scraps were ground into fine powder with various sizes from less than $100{\mu}m$ up to about $1000{\mu}m$ using two types of tailor-made pulverizers. The compounds were prepared in a modular intermeshing co-rotating twin screw extruder at various conditions such as different compositions, types and powder sizes of waste XLPE, screw configurations and various polymer matrices (LDPE, HDPE, PP, PS). The mechanical and rheological properties and the fracture surface or the compounds were investigated. It was found that an improved impact strength was obtained from the compound with white XLPE powder pulverized from the scraps without outer/inner semi-conductive layers. Generally, the impact strength increases with the content of XLPE but decreases with the size of XLPE. Especially for LDPE, the extrusion was possible up to 80 wt% loading of XLPE. Also, the impact strength increases with the number of kneading disc blocks in the given screw configurations. The melt viscosity of the compounds increases with increasing XLPE loading. However, the higher shear thinning behavior of the compounds at common shear rates implies proper processibility of the compounds. In addition, the impact strength for other polymer matrices used increases with XLPE and it is noticeable that the impact strength of PS/XLPE (80/20 wt%) compound was improved twice that of pure PS.

  • Many researchers have increased the loading level of electrodes to improve the energy density of secondary batteries. In this study, high-loading NCM523 (LiNi0.5Co0.2Mn0.3O2) positive electrode is manufactured using a polytetrafluoroethylene (PTFE) binder, not the conventional polyvinylidene fluoride (PVdF) binder, which has been commonly used in lithium-ion batteries. Through the kneading process using PTFE suspension, not the conventional slurry process using PVdF solution in N-methyl-2-pyrrolidinone (NMP), thick electrodes with high loading are easily manufactured. When the PTFE and PVdF-based electrodes are prepared at a loading level of 5.0 mAh/cm2, respectively, the PTFE-based electrode shows better cycle performance and rate capability than those of PVdF-based electrodes. The electrode manufactured by the kneading process using a PTFE binder has high electrode porosity due to insufficient roll-press, but the porosity can be lowered by high temperature roll-press over 120℃. However, there is no significant difference in cycle performance according to the roll press temperature. In addition, the cycle performance of the high loading electrode is slightly improved by increasing the content of the conductive material. Overall, the PTFE binder can improve the performance of the high loading electrode, but additional solutions will be needed.
