A soil investigation has identified that there is bedrock at depth beneath the site 1. What are the definitions for "Intrusive Igneous Rocks" and "Extrusive Igneous Rocks"? How these two types of rocks are similar and different? (Explain one similarity and one difference). Name one example rock for each type. (8 marks) It is intended that concrete will be used for a ground bearing floor slab. You are tasked with researching about the material and the appropriate batch tests required 2. What are the main material components of concrete and approximately what percentages of concrete is made of each component? (8 marks) 3. Research three other minor material component types (additives) which can be integrated into concrete mixes and describe the benefit of using them in concrete mixes. (9 marks) Batch testing is to be undertaken to verify the properties of a particular batch of concrete. You are tasked with researching types of batch testing in readiness for onsite activities for the project 4. Explain "Workability" in concrete and explain how it is related to the water- cement ratio? Name one test that is used to measure workability on site. (8 marks) 5. Explain the significance of measuring the mechanical properties of hardened concrete and where it may be used in the design process. Describe one method (include detailed processes) that can be used to measure the compressive strength of the concrete batch. (9 marks) Steel is the material to be used for the frame of the external stairwell. 6. Name (with a brief explanation) corrosion mechanism (s) in steel. (8 marks) (Total 50 marks)
