Until now, reuse for cement, construction materials (e.g. gypsum), civil engineering material (e.g. asphalt filler) was mainly pursued and more efforts will be projected toward these streams. The problem is how far we could recover the treatment cost.

Comparing the topics covered by these two options, you will find that the Other Discipline option covers topics similar to the morning session topics but more in depth, while the Civil Engineering option covers seven civil engineering technical areas and civil engineering materials. Depending on how widely your curriculum covers these topics, you may choose one option against the other. In either case, the problems are more in... 

It is suggested here that introductory soil mechanics can instead present soil as one of many civil engineering materials and use opportunities to indicate overlaps between subjects. In understanding stiffness and strength the key feature of soils, compared to (say) metals, is that soils contain voids, which permit significant changes in density. Thus a critical state soil... 

For other civil engineering materials a key introductory mechanical property is stiffness - elasticity underpins much of the treatment of structural mechanics. Elasticity itself is not particularly applicable to soils but the concept of stiffness certainly is and, having introduced the idea of soil with compressible voids, we can conduct a thought experiment (arguing from physical instinct rather than from actual observation) to describe how we expect soil to behave when it is compressed one-dimensionally (Fig 2a). The soil is confined so we expect the stiffness to increase nonlinearly as the soil becomes more dense and the stress level rises. It is helpful then to describe this nonlinearity using a power law (Janbu 1963).

Steel fibres continue to have a wide range of apphcations in civil engineering materials. There are some structural applications where they have been used in concrete without any conventional reinforcing bars. These have been short span, elevated slabs, for example a parking garage at Heathrow Airport...

For obvious reasons, all structures should be designed to avoid brittle fracture of any kind however, under particular conditions, such fracture may occur in practically all materials. For metals or plastics, if brittle fracture is conditioned by low temperature, fatigue, rate of loading, etc., it is a natural and common way of fracture for several kinds of matrices used in building and civil engineering materials. Matrices based on various cements and all kinds of ceramic materials are considered as brittle. Brittleness is the principal disadvantage, which should be controlled in all structural and even non-structural applications of these materials.
