Mortars and concretes are mixtures of binding materials, aggregates and water that harden over time. Mortar is used to bind bricks, stones or tiles, while concrete includes both fine and coarse aggregates. There are many types of mortars and concretes classified according to their binding materials, designs and purposes. Cement mortar and concrete provide high strength and durability, while lime and mud mortars are cheaper but weaker. Reinforced concrete includes steel reinforcement to take tensile stresses.

11. For wide joints in paving or for stonework, either as paving or as walling, a coarser mortar is often preferred - replace half of the building/soft sand with grit/sharp sand. You will probably find that a coarse mortar such as this requires less gauging water to achieve a working consistency than does a bricklaying/general purpose mortar. 2 x Building Sand plus 2 x Grit Sand plus 1 x cement Mortar for Wide Joints
