Case Study: Concrete Curing Stress Tests
Before and After
Make Sidewalk Strength Concrete, 32 MPA.
Cure it in varying conditions, test strength.
Write a report.
Some of the concrete was immersed in water 30 days, some not at all.
Some was surface wetted during curing: 1 day, 3 days, 7 days, 14 days.
The team assemble in the Lab, plus John of MyMason (not shown).
The Lab is in the ALgonquin College School of Construction Excellence.
This machine will crush the samples and record the point of failure.
The concrete was mixed and set into plastic cylindrical forms.
The forms were removed after setting and then given differing treatments.
It isn't quite the same as concrete in a wood form outdoors, but it is interesting.
The graph shows the comparative strength during compression testing.
The concrete totally immersed in water for 30 days was strongest.
Surface wetting of the concrete produced a slightly less strong result.
A cure with a 'curing-sealant' and a dry cure with no wetting were worst.
Three samples were made for each test.
A final report will be posted here soon (Spring 2014).
This team received a 19.5/20 for their work.
It was a pleasure to work with them to demonstrate the range of results.
