The Differences Between Cement, Concrete, and Mortar
The Spruce / Liz Moskowitz. Concrete . Concrete is a complete building material used for foundation walls, concrete slabs, patios, and many other masonry structures. It is uniquely versatile because it starts out as a simple, dry mixture, then becomes a flexible, semi-liquid material capable of forming into any mold or shape, and which dries into the hard-as-rock material we know as concrete.

Stone dust vs sand for laying pavers? Help!
The local stone yard calles it "road base" among other things. Four to six inches of that stuff are compacted before the stone and levelling sand are laid. For filling in gaps, we have always used mason sand for pavers and bricks, and actually we just use the road base itself to fill in for a flagstone application. Just my 2 cents.

So in order to make your concrete last as long as your money that went into it, adding a layer of crushed stone under a slab of concrete will increase the life of your investment. Here are 3 reasons why a layer of crushed stone is important to the life of your concrete:
What is the Difference Between Mortar and Concrete?
Like mortar, concrete is a mixture of sand, cement, and water, but it also contains rock chippings or gravel which makes it much stronger and more durable than mortar. Because it needs a low water to cement ratio, it is much thinner when mixed, making it difficult to use as a bonding element. Concrete is used in structural projects and is often ...
Use of stone powder in concrete and mortar as an ...
normal sand and brick chip. Concrete of stone powder and brick chip gained about 10% higher strength than that of the concrete normal sand and stone chip concrete. The highest compressive strength of mortar found from stone powder which is 33.02 Mpa, shows that better mortar can be prepared by the stone powder.
Can I put pavers right over concrete walk?
Concrete pavers tend to effloresce. This is a problem for most manufacturers of concrete products. Attaching concrete pavers using grout or a concrete mix will trap water (when it is applied) in between the pavers causing the paver to turn white, especially around the edges of the pavers. My experience with an "overlay" has given me a new approach.
