Select one: Primarily used with cut roofs Primarily used with pitched roofs Primarily used with truss roofs Primarily used with conventional roofs Primarily used with coupled roofs When discussing steel reinforcement with a structural engineer and he suggests placing a "cogged" bar into the slab reinforcement. What does "cogged" mean Select one: The steel reinforcing bar is cut to the length he suggests The steel reinforcing mesh is cut to the shape he suggests The steel reinforcing bar is bent at 90 degree angles "Cogging" only refers to the steels ductility The steel reinforcing Trench Mesh is bent to the shape he suggests Slab quiz pass mark 80%: Attempt review https://learn.sydneytafe.edu.au/mod/quiz/review.php?attempt=132910... 1 of 10 3/7/2024, 9:50 PM
Question 3 Correct Mark 1 out of 1 Question 4 Correct Mark 1 out of 1 Question 5 Correct Mark 1 out of 1 Bearing pressure changes with different soil types. Select one: True False What is the pier (post) in pier and beam construction? Select one: The pier is the hole, when it is filled with concrete it is a pile. The pier is the reinforcement and the pile is when the concrete is added The pier is a strip footing which is deeper than it is wider. The pier is another name for a Raft slab. The pier is a vertical cylinder of normally unreinforced concrete that is made by drilling a hole into the ground then filling with concrete. Ideally the bottom of a pad footing should be on the same bearing material as the strip footing.

Question 8 Correct Mark 1 out of 1 Answer below questions from the Structural notes below. When placing concrete the engineer has specified what cover to the slab in contact with the ground. 40 mm Does the Engineer nominate any admixtures? No When ordering concrete the engineer has specified what slump for the footings 80 mm All steel reinforcing and principles will follow the Australian Standard ............ ? As 3600 Reinforcing will be supported by bar chairs at what max.centres? 600 mm When placing concrete the engineer has specified what cover to the footings in contact with the ground. 50 mm All concrete should be "wet" cured for ____________how long? 1 Week Slab quiz pass mark 80%: Attempt review https://learn.sydneytafe.edu.au/mod/quiz/review.php?attempt=132910... 4 of 10 3/7/2024, 9:50 PM

Select one: a. Slab Fabric, shallow footings and deep footings b. (b) and (c) c. Trench mesh, pier hole mesh and rods d. Bars, Slab Fabric and Strip Footings e. Bars, Slab Fabric and trench mesh For basic footings when ordering concrete what does 20/20 mean? Select one: 20% accelerator and 20% retarder to the concrete 20 mm minimum a ggregate size no maximuml aggregate size and 20 mls of additive 20 Mpa concrete strength and 20 minutes truck turn around time 20 Mpa concrete strength and 20 mm nominal aggregate size Slab quiz pass mark 80%: Attempt review https://learn.sydneytafe.edu.au/mod/quiz/review.php?attempt=132910... 5 of 10 3/7/2024, 9:50 PM

Select one: True False Why would you place compressible material under the beam in 'pier & beam' construction? Select one: AS 2870 suggests to use compressible material in all pier & beam situations. to accommodate ground sag to rid the site off unusable material that is inorganic in nature to accommodate ground heave to allow the ground to contract Concrete is strong in __________________________?

Question 15 Correct Mark 1 out of 1 Question 16 Incorrect Mark 0 out of 1 Question 17 Correct Mark 1 out of 1 Pad footings are sometimes known as ___________? Select one: Small footings Bob footings Blob footings Back footings If not directed by design engineer, what is the ideal distance from top of the strip footing to the finished ground level? Select one: 50 - 75mm 1 - 5mm 75 - 150mm 250 - 350mm 150 - 250mm What type of load support system is pier and beam construction? Select one: a. This system of footing basically the same as Pyramid construction. b. This system of footing is basically a series trench mesh connected with DN bars to provide a vertical means of support. c.
