To make concrete there are four basic materials you need: 1. Portland cement - You can buy this in a 94lb bag 2. Sand - Course or Fine will work (course sand will give you a stronger mix) 3. Aggregate (stone) You can use 3/8", 1/2", or 1/5" stone for aggregate 4. Water - Clean cool water is best.
Cambridge Pavers: a manufactured paving stone, with an extra dense top layer of Armortec. Cantera Stone: a natural stone, quarried in Mexico.

Timing. Ideally, when working with paving that has been laid on a cement-bound bed and or with buttering mortar, the pointing should be undertaken within 4 hours of the paving being laid, while the joints still have fairly fresh mortar within them from the buttering process. The pointing will 'top-up' the buttered mortar to form a solid mass with no day …
