Concrete and mortar are two most vital building elements for any construction work. But both the materials are different in nature. Go through the following article to know the fundamental discrepancies among concrete and mortar.
Concrete:
Concrete is a composite material produced from a mixture of sand, cement, aggregates and water in required proportions.
Concrete refers to a composite material that is formed with some basic elements like water, aggregate (rock, sand, or gravel) and amalgamated with a fluid cement that hardens in due course.
If aggregate is combined jointly with dry Portland cement and water, it produces a fluid mass that can be smoothly molded into shape. A chemical reaction happens between cement, water and other ingredients to develop a hard matrix that joins the materials together into a strong stone-like material.[2] Sometimes, additives like pozzolans or superplasticizers are provided in the mixture to make the physical properties of the wet mix or the finished material superior.
Mortar:
Mortar is developed by mixing cement, sand and water and applied to tie building blocks like stones, bricks, and concrete masonry units jointly as well as fill and close the uneven gaps among them.
VARIANCE AMONG MORTAR AND CONCRETE:
1. Concrete is developed by mixing cement, sand, aggregates and water, whereas the mortar is formed by mixing cement, sand and water.
2. Concrete is more durable as compared to mortar.
3. The water-cement ratio is greater in mortar. The water is utilized to hydrate the cement and retain the mix collectively. But the objective of concrete is to maintain the water-cement ratio as low as possible.
4. After mixing, Mortar becomes much condensed substance as compared to concrete. Mortar acts like a glue to fix the bricks together. Because of superior strength and longevity concrete is mostly recommended for all types of construction works like buildings, bridges, roads etc.
5. Concrete sustains for a long time but mortar should be substituted by every 20 – 30 years.
