Problem 1: Concrete specifications:
A friend recently had some concrete poured as part of an outdoor patio area. After several months of use the concrete surface is very powdery, prone to crumbling and not wearing well. You offer to inspect the work and give your opinion.
Give an explanation into why you think the concrete is looking and behaving the way it is.
Is there a solution to your friend's problem?
Problem2: Concrete ordering:
You are about to order a batch of concrete for a slab being poured in a few days time at 123 High St, Bigtown. You want the truck to arrive at 8:30am.
What are essential things you need to tell the supplier to ensure you get the right concrete for the job? (Remember to tell the supplier the obvious details as well!)
Problem 3: Concrete defects:
A building about 10-15 years old, built by the ocean has concrete beam across the top of an outdoor café area. You look up to see exposed rusty steel reinforcement with sections of concrete missing from around it. This is clearly a problem especially in the location it is in (café).
