Apr 06, 2005Bear in mind it takes about 28 days for concrete to reach its full strength. The mix described above gives a (probable) crushing strength of about 40N/mm2. The alternative is to use a section of concrete lintel or just buy a padstone. Unfortunately, standard padstones don't come in 152mm (standard sizes jump form 140 to 215).

Feb 18, 2008Re insulating board under concrete slab??? Sure, structurally it's fine, so long as what you get is rated for it. At least in theory. The crush strength is quite high, it's spread out over a large area, and it's hidden from most of the things that cause petro-products to decompose.

Concrete mix ratio of 133 On mixing 1 part cement, 3 parts sand with 3 parts aggregate produces concrete with a compressive strength of 3000 psi. On mixing water with the three ingredients, a paste is formed that binds them together till the concrete mix gets hardened. The strength concrete is inversely proportional to the water/cement ratio.

Properties of concrete Wikipedia. In very high-strength concrete mixtures (greater than 70 MPa) the crushing strength of the aggregate can be a limiting factor to the ultimate compressive strength In lean concretes (with a high water-cement ratio) the crushing strength of the aggregates is not so significant

Sep 21, 2007The type of concrete in a concrete block is a zero slump mix and not a wet cast concrete with curing in the plant. Typically, this type of concrete will be closer to 90% when used. The cheapest and easiest way to increase the strength of a concrete masonry unit is to add extra water to this type of mix, but contractors would not buy the block.
