Mortar and concrete are both important building materials widely used construction fields. In compositions, mortar is the end product of mainly mixing cement, sand and water, but there are special mortar possessing certain properties by adding some mixtures or additives. Concrete is the end product of mainly mixing cement, aggregates (sand and gravel), water and other additives. Concrete also has various classifications according to its different components proportion for different applications purposes. Therefore, we can easily find that the main difference between them is that there is no coarse aggregate (gravel) in the composition of mortar. Thus, building mortar is also called the fine aggregate concrete; In applications, mortar is used as an adhesive that can hold bricks and blocks together, or hold paving slabs in place. It can also be used as an exterior finish. The coarse aggregates in concrete make it much stronger and more durable than mortar for use in structural projects such as beams, walls, or other building foundations. In water to cement ratio, the water to cement ratio in mortar is higher than in concrete. When mixed, the mortar is a much thicker substance than concrete, making it ideal as a glue for building materials like bricks.
