Different types of concretes and their applications
We all have heard the song from the movie Lagaan “Toot Gayi Jo Ungli Utthi Paanchon Mili To Ban Gayi Mutthi” which roughly translates to “we’ll achieve strength only when we all come together”. Similar is the case with cement concrete. Cement, water, sand, gravel and steel rods will only lend the ideal strength when used together in proper ratios.
Concrete is a construction material composed of cement, fine aggregates (sand) and coarse aggregates mixed with water which hardens with time. Portland cement is the most commonly used type of cement for the production of concrete.
Different types of concrete are produced to satisfy specific purposes in construction based on the constituent material, mix design, the method of construction, area of application, a form of hydration reaction.
Although there are many types of cement concretes, here we have enlisted most common types which we usually see on an everyday basis.
It is the most common type of cement concrete which is made by mixing Portland cement with both an aggregate, sand and water-chemical mixtures. It is mostly mixed manually in improvised containers.
Application: It is used in mortar for plastering, masonry work, pointing, etc. It is used for making joints for drains and pipes. It is used for a water tightness of the structure. It is used in concrete for laying floors, roofs and constructing lintels, beams, stairs, pillars, etc.
High-strength concrete is different from normal-strength concrete in the amount of force it can resist without breaking. The American Concrete Institute differentiates high-strength from normal-strength at a compressive strength of over 6,000 psi (pounds square inch).
Application: High-strength concrete is typically used in the erection of high-rise structures. It has been used in components such as columns (especially on lower floors where the loads will be greatest), shear walls, and foundations.
HIGH-PERFORMANCE CONCRETE (HPC)
High-performance concrete provides ease of placement without affecting strength, long-term structural properties, longevity and toughness in various weather conditions. While all High- Strength Concrete are High Performance, not all high-performance concrete is high-strength.
Application: High-performance concrete has been primarily used in the construction of tunnels, bridges, pavements, high rise building structures because of its strength, durability, and high modulus of elasticity.
