INTRODUCTION In the cloud point experiment‚ waxes will appear and thickens the oil and clogs fuel filter and injectors in engines. The wax also accumulates on the cold surfaces and forms an emulsion with water. The appearances of cloud point determine the first cloud of wax crystals in a liquid when it is cooled. Whereas‚ pour point experiment is to determine the minimum temperature of the oil which will

SELF-COMPACTING CONCRETE Masahiro OUCHI 1 SUMMARY Self-compacting concrete was first developed 1988 in order to achieve durable concrete structures. Since then‚ various investigations have been carried out and the concrete has been used in practical structures in Japan‚ mainly by large construction companies. Investigations for establishing a rational mix-design method and self-compactability testing methods have been carried out to make the concrete the standard one. Keywords: self-compacting

in the area of civic buildings. What distinguishes Roman architecture is its technical advances which allowed the Romans to define space uniquely and impressively only using materials as simple as bricks and concrete. A civilisation known for its efficiency‚ the Romans developed concrete as a building material as it was durable‚ strong and economical‚ and particularly well suited in the construction of large-scale buildings. Such buildings as the Temple of Diana (ca.80 CE) in Nimes used cut-stone

Concrete operations are the third stage of Piagetian cognitive development‚ during which children develop logical but not abstract thinking (Papalia p.351). The concrete operational stage begins around age seven and continues until approximately age eleven. During this time‚ children gain a better understanding of mental operations. Children begin thinking logically about concrete events‚ but have difficulty understanding abstract or hypothetical concepts. Piaget determined that children in the

Magan Agarwal Binani Cement Limited Key factors that control the compatibility between Naphthalene-based super plasticizers and ordinary Portland cements Synopsis: Super plasticizers improve the workability of concrete at low water cement ratio but this workability is sometimes lost rapidly in the first hour after contact between the cement and water. This is especially the case for naphthalene-based and melamine-based superplasticizers when used with the so called incompatible cements. It
