Rapid Hardening Concrete is a special type of concrete that is used for construction purposes. It gets its name from the fact that it hardens much faster than conventional concrete. This is due to a chemical reaction that occurs within the cement as it comes into contact with water. This chemical reaction causes the cement to expand and harden in a short period of time.
Rapid Hardening Cement is also called hydraulic cement, because it has been chemically treated to speed up the hardening process. There are several advantages to using rapid hardening concrete for construction projects. First, this type of cement can be poured into forms at any temperature and will set in less than an hour without the need for additional heat or electricity. In fact, many contractors prefer this method because they do not have to wait for the weather to warm up before pouring their foundation!
This blog is dedicated to the subject of rapid hardening concrete. As with any construction material, there are many different types of concrete that have different applications and uses. The different brands of rapid hardening concrete on the market each have their own unique characteristics, but they all have the same basic purpose: to set and harden rapidly so that your project can be completed faster than it could with traditional concrete.
Rapid-setting concrete is used in a wide range of projects including driveways, sidewalks, curbs, foundations and industrial applications. In fact, many of these projects would be impossible without rapid-setting concrete because they require a strong base that will not erode during construction or over time. Many contractors use rapid-setting concrete to complete their projects under budget and on schedule.
There are many factors that go into choosing the right type of concrete for your project. These include how quickly you need it to set and how much money you can spend on the material. The type of project you are working on will also determine what kind of concrete you should use. If you are building a foundation for a house or other large structure, then it is best to use fast setting cement since it will set quickly and last longer than other types of cement due to its high water
Rapid hardening concrete is a special type of concrete that is used in construction. It can be identified as a concrete that gains strength very quickly when compared to normal concrete. Normal portland cement takes months to reach its full strength but rapid hardening concrete reaches its full strength in just a few days.
Rapid hardening cement is an ordinary portland cement with high early strength. It is manufactured by adding accelerators such as calcium chloride or by increasing the fineness of the cement so that the hydration process is speeded up.
Rapid hardening cements are used for below-grade applications such as tunnel construction, dams and foundations where high early strength gain is needed. They are also used for patching and repairing the existing structures.
Rapid Hardening Concrete is a type of concrete that is able to gain strength at a rapid rate, even at early ages. It is used in applications where formwork removal and early serviceability are required.It is usually specified for repair and rehabilitation works. The key ingredients in rapid hardening concrete are the cementitious materials like fly-ash,furnace slag and silica fume along with suitable admixtures.
Rapid Hardening Concrete is known by many different names such as fast tracking concrete,fast setting concrete, quick track concrete etc. In general any concrete which attains sufficient strength for further processing within 24 hours can be termed as Rapid Setting Concrete.
The most common applications of Rapid Hardening Concrete are repair and rehabilitation works in areas where the traffic needs to be restored within a short period of time. With suitable mix design and use of appropriate admixtures, it is possible to obtain high strength even at an early age of 3 hours.
The standard specifications for RHC have been published by several agencies. Some of them are as follows:
– ASTM C1609/C1609M – 10 Standard Test Method for Flexural Performance of Fiber-Reinforced Concrete (Using Beam With Third-Point Loading
When working with concrete, it is important to understand that each type of concrete has a set shelf life. This means that if you don’t use the concrete before it sets, then you will have no choice but to discard it.
The amount of time that a batch of concrete can last before setting depends on the type of cement that you are using. Portland cement, for instance, is known for having a relatively short shelf life. In fact, depending on the temperature and humidity in the air, Portland cement may begin to set within just an hour or two after being mixed with water.
This is why many construction professionals prefer to use rapid-setting cement instead of Portland cement. Rapid-setting cement is specially-designed so that each batch has a longer shelf life than conventional Portland cement. This means that you can work with your batch of concrete for a longer period of time without worrying about it setting prematurely.

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently in the past a lime-based cement binder, such as lime putty, but sometimes with other hydraulic cements, such as a calcium aluminate cement or Portland Cement. Concrete is distinguished from cement by its much greater volume for a given weight: concrete is about one-tenth as dense but two hundred times as strong as cement. Most common cements are hydraulic cements made from lime or calcium silicate. These materials react with water to produce an amorphous calcium silicate hydrate (“liquid stone”) that fills in the spaces between the gravel or sand particles in the concrete mix and binds them together into an artificial stone-like mass called concrete.
Concrete is widely used for making architectural structures, foundations, brick/block walls,
