Differences between Concrete, Mortar and Grout

Title: Differences between Concrete, Mortar and Grout
Concrete, mortar, and grout are three distinct mixtures used in the construction industry. Despite the tree mixtures sharing same components, they are used for different purposes in a construction site. The author describes mortar as a mixture of sand and cement as is mostly used in the building of brick or block walls so that they can be held together (Sealzville et al. 43). The composition of mortar is water, cement, and sand where water is used in the hydration of cement so that it can hold the mixture together. The ratio of water to cement is always higher in mortar as compared to concrete so as it can form its bonding property. Mortar is also thicker than concrete thus making it act as a glue for joining material such as bricks and blocks during construction.
On the other hand, the authors claim that concrete is a mixture of sand, cement, water as well as gravel which are rock chippings are thus making it stronger as compared to the mortar (Hewlett and Peter 308). Concrete requires low cement to water ratio, it is always thinner when mixed thus making it stronger and more durable as compared to grout and mortar. The thinness of concrete when mixed makes it hard to use it as a bonding element thus being used in structural projects where it reinforced with steel so that it can retain its strength even when the soil beneath it settles. Concrete is normally used for support by being used in the construction of beams, building foundations as well as walls.
According to Theryo et al, “grout is a paste that is commonly used in filling gaps between walls or tiles after the adhesive mortar below so as to link the pre-cast sections of the concrete” (124). Grout is made up of cement and water alone while concrete has gravel. Concrete is capable of resisting to harsh climate and support of heavyweights, something that grout is not capable of. Grout consists of more water as compared to both mortar and concrete so that it can be easier for it to flow and be used in the filling of joints.
Both mortar concrete and grout consist of two elements in common that is water and cement but for the case of concrete and mortar, gravel and sand are added respectively so as to serve their purposes fully and bear the environmental condition they are exposed to.
