GEOTECHNICAL INSTRUMENTATION Cement-Bentonite Grout Backfill for Borehole Instruments P. Erik Mikkelsen Solid Bentonite Seals The backfill for a borehole instrument is often an item that receives a disproportionate lack of attention. The behavior of the backfill‚ the material that is in the most intimate contact with both the formation and the instrument‚ is critical for obtaining correct measurements. In many situations‚ instrument observations may just reflect unstable backfill‚

PET BOTTLES AS BRICKS To make the environment free from pollution an attempt was made to construct the water tank using the discarded pet bottles. Since there is construction materials scarcity‚ we need to go for an alternative construction material. The three basic needs for human life are food‚ shelter and clothing. But in developing countries like India there is no shelter for poor people. By considering this‚ the shelter can be constructed at low cost. Making of brick emits carbon-di-oxide

1.0 INTRODUCTION: AISI 304L austenitic stainless steel is widely used as engineering materials due to its high strength and good corrosion resistance properties. However‚ AISI 304L stainless steel undergoes extensive wear and erosion when applied as components in aggressive environments such as petro- chemical and marine atmosphere [1]. Solid particle erosion is defined as the progressive loss of material from a solid surface due to mechanical interaction between the surface and some fluid entrained

Page 88-90 stated that plastics are polymers and are chemically unreactive because they are held together by stable single bonds‚ which also results in their chemical stability. The stability of plastics makes them resilient to breakage making them good replacements for fragile items such as glass. Some plastics are weakened and dissolved by organic non-solvents so not all plastics can be used for the same purposes. Plastics are moulded to different shapes with some being flexible like plastic bags
