Title:

“Lightweight concrete used in the construction of medium rise buildings”

Aim:

The aim of this report is to discover and explore information on lightweight concrete as well as identify this materials suitability within the construction industry for structural applications.

The main goals that will be incorporated throughout this report are listed below:

1. Understand how lightweight concrete can be used as a construction material in medium rise buildings.
2. Understanding types of treatment process of lightweight concrete. When treating this material, it is important to consider the environmental impacts, costs and the best methods used.
3. Method of installation of lightweight concrete, including the design of the material and type of joints used (i.e. fixed joints, connections etc.).
4. Its applications in commercial, residential and industrial buildings.
5. Research different types of lightweight concrete that can be used for construction.
6. Lastly, to determine the suitability of lightweight concrete used in the construction industry. This may include; advantages, disadvantages, environmental impacts, structural load capacity, thermal properties, etc.

Requirements:

o More topics are expected to be included (other than the ones listed above) in appropriate heading and sub-heading format.
o This report will be submitted to an Australian university so information obtained on this product should come from Australian sources and manufacturers for example “Hebel blocks Pty Ltd”.
o The report should focus on the application of lightweight concrete in Australia and not other countries unless it is about its manufacturing and import/export operations for Australia.
o The report should include a summary of the history of the product and its uses in Australia.
o Any mention of numbers/calculations in units should be in the metric system, (e.g. t, kg, m, cm).
o The report should include an abstract and introduction.
o Report should include charts, diagrams, tables and other forms of visual aids which will help in improving the understanding of the report to the reader.
o The report should include opinionated statements and judgements in regards to the application of lightweight concrete in medium rise buildings from an engineering perspective (general thesis requirements) for example recommendations, alternatives etc.
o The reader should be able to establish that the report contains a lot of research on the topic and has been referenced well.
o The report should include appendices, tables and other information at the end, that relate to the body of the report (if necessary). For example; graphs, data, tables and booklets from companies and manufacturers.
o The report should include headings and sub-headings to separate components of the report.
o The report is not to be plagiarised from other related journal articles, academic resources, internet websites or any other person’s previous works.
o The report needs to be completed at a fourth year undergraduate level.
o This capstone report should predominately contain information and research, (i.e. 85% information and research, 15% appendices, bibliography, graphs, tables etc)

D.V., age 42, has a history of HIV infection with the development of AIDS 2 years ago. He has been hospitalized and treated twice for Pnuemocystis jiroveci pneumonia and is now admitted to ICU with a suspected cryptococcal meningitis. ICP monitoring is instituted, and an arterial line and flow directed pulmonary artery catheter are inserted. Endotracheal intubation with assist-control mechanical ventilation at 12 breaths/min, 15 cm H20 PEEP, and FI02 of 50% is established. (Note: this patient is very critically ill and requires you to review ICP, septic shock, multiple organ dysfunction syndrome (MODS), and respiratory failure).
