Question
4. Briefly describe: geonets, geocells and degradable erosion mats. 5. The tensile strength of blue gum timber is 50 MPa at a moisture content of 12 percent. If the strength determined in its green state was 42 MPa, and its fibre saturation point occurs at a moisture content of 25 °C, find the strength of this timber at a moisture content of 8 percent. If the density of the wood was 1.4 g/cm' at moisture content of 12 percent, find the density at a moisture content of 8 percent. 6. (a) Briefly describe glass as a building material. (b) Briefly describe three main types of paint. (i) Assuming paint has 42 percent volume of solids, find the area that 1 litre will cover when a dry film thickness of 38.1 microns is required. (ii) The walls of a room are 3 metres high, with a total of 30 metres of wall length. The total door and window area is 3 square metres. If the spreading rate is 11 square metres per litre, and only two coats of paint are required, work out how much paint is needed.
