Hi Gang!!

This is the last in a series of review for tomorrow’s written “formative evaluation” as Dave keeps correcting me!

Firstly, Chase asked me to clarify the answer to question 8, which I would be delighted to do as he is reading the blog and needs to be rewarded!

Question 8 revisited:

The task and the tools associated with them:

  • installation of anchors = anchor bolts
  • proper consolidation = vibration
  • 1st finishing = screed board
  • create slopes for drainage on slab = laser level
  • final finishing = use steel trowel or power trowel (concrete sealer after curing)
  • use of reinforcing material = construction trellis
  • 2nd step for finishing = magnesium float
  • edge finishing = edger
  • create control joints = cut kerfs with concrete saw
  • verify consistency = slump cone

Thanks, Chase, I am sure everyone is happy you asked!

Question 14
