In fact the footings size and reinforcements are exactly the same for cip concrete foundation walls and CMU foundations. The biggest difference is the dowls that provide vertical reinforcements for the block wall which can be as close as 8 inches on center (every cell), 16 inches on center (every other cell), 32 inches on center or max at 48 inches on center.

Most road base material approved by the local DOT is suitable for the subbase. “We use 6 to 8 inches of crusher run,” says Steve Lloyd, Lloyd Concrete Services, Forest, Va.
Poured concrete foundations are more prone to shifts in the ground and water pressure than ICF foundations. So, poured concrete foundations are more at risk of cracking and leaking, which can lead to mold and mildew growth. ICF and poured concrete foundations both strive to support a building and resist lateral forces and buckling.

Before the concrete is scooped into the moulds, the moulds must be lightly coated in a mould release agent. This ensures that the concrete does not stick to the mould and makes it easier to remove the cube. When using a 150mm mould, the concrete sample is scooped into the mould in 3 equal layers (50mm) and compacted between each layer.
Precast concrete shear wall panels provide a lateral load-resisting system when combined with the diaphragm action of the floor construction. The effectiveness of precast concrete shear walls is largely dependent on the panel-to-panel connections. In some cases, precast panels are used as formwork for cast-in-place concrete.
Crusher dust, or quarried and crushed rock too small for use on roadbeds, makes an excellent material for a pathway. Rain, time, and foot traffic will cause it to harden to near concrete firmness. Read on to explore pathway ideas and learn how to employ crusher dust in your pathway project. Step 1 - Plan.
Forming a compacted sub base, small pieces of concrete are laid down as the lower layer in highways, driveways, roads, patios and even in redi-mix concrete foundations, though crushed stone is typically preferred beneath such foundations.

The weaker the subgrade, or the heavier the loads, then, the thicker the slab needs to be. Concrete strength also comes into play, but most slab concrete is around 3000 to 4000 psi, so it's not a major factor. The tensile strength of concrete is typically taken as 10 to 15% of the compressive strength, so only about 400 or 500 psi.
