I need to specify concretes for the below uses (must include slump & compressive strength classes)?

Question

I also need to know the properties and performance in use, for;

1)Strip Foundations for 2 storey dwelling

2)precast prestressed concrete floor slabs for multi-storey office block

3)concrete paving for a lorry unloading area adjacent to a warehouse

4) columns and floor slabs cast in situ for a 3 storey building.

i have trawled the internet and books with no luck, you guys could just save my life!!

p.s. this is for an assignment not for real- so no need to worry about being slightly off and causing failures in use!!

Answer 1

Go to the library and sit and look through the UBC, uniform building code. All of your questions above are addressed in the UBC concrete section. (and it's actually nice to sit in a real library for once instead of searching the internet dirt-road)
