if wet concrete loses its shape or 'slumps' too easily, the balance is not right. - 4What is the purpose of a compressive test ?A compressive test checks that the hardened concrete is strong enough to withstand loads.
- 5Which test would I use to test the mix of wet cement ?Slump
- 6Which test would I use to check a hardened concrete is strong enough to withstand loads ?Compressive
- 7Where might timber be used in a structure ?The frame of the building
Roof trusses
Doors
Windows - 8Stress grading or strength testing refers to what ?Sorting timber into various groups based on their strength
