Mix the concrete well and you ll pour a slab that s likely to reach the concrete s rated compression strength.
Concrete mix floor slab.
Ideal for wall foundations or bases and laying paving slabs etc.
Quality floor construction includes good subgrade compaction even thickness slabs low slump concrete straight bulkhead lines and control cuts spaced 24 to 30 times the slab thickness.
Used for exposed paving such as driveways and garage floors.
Common mistakes in concrete floor slab construction can be avoided with proper base preparation mix design placement finishing and curing.

This is ideal for foundations footers and heavy equipment.
C35 concrete mix this type of mix is most suited to commercial applications such as slabs and bases and for the bases of areas that may be subjected to weight c40 concrete mix the c40 mix is a very strong mix and is ideal for paving that will receive sustained footfall or for other areas such as parking bays for heavy vehicles.
Foundation concrete 1 2 3 mix.
Paving concrete 1 1 2 mix.
If using combined aggregate this mix would be 1 5.
What is the ratio for mixing concrete.
When durability is key high strength concrete makes a great choice.
Foundations driveways patios rv slabs sidewalks.
One of the best concrete mix ratios is 1 part cement 3 parts sand and 3 parts aggregate this will produce approximately a 3000 psi concrete mix.
