What Is Quick-Setting Cement?

Quick-setting cement is a kind of cement with a setting time between 5 to 30 minutes, used primarily for special situations during construction, like constantly in the case of running water. Compared to conventional cement formulations, quick-setting ones are made from a unique formula that decreases the waiting time while increasing the compressive strength. 

Although this cement formulation is able to get rid of its plasticity faster than ordinary Portland cement yet, it fails to get hold of an increasing rate of power or strength. Made from well-grinded clinkers of cement, the number of quick-setting cement uses are many in the world of construction.

Advantages Of Using Quick-Setting Cement:

The benefits of using quick-setting cement like ultratech quick-setting cement are as follows, 

• Firstly, quick-setting formulation of cement is often used for repairing concrete construction structures because this cement does not disturb the form in any way.
• Although the setting time for quick-setting cement is lesser than ordinary Portland cement, the final strength obtained in the case of both is very similar.
• Thirdly, the reason why this cement formulation is often used for constructions involving running water is due to its high-resistance capabilities to water. 
• Lastly, the quantity of water needed during the process of hydration is also low in the case of a quick-setting formulation. 

Disadvantages Of Using Quick-Setting Cement:

The cons of using quick-setting cement like ultratech quick-setting cement are as follows, 

• Quick-setting cement contains aluminum sulfate. Due to the high content of sulfates in the formulation, not only is durability negatively impacted, but also the risk of sulfate attack prevails. 
• When water is added to this type of cement, it is mandatory to complete the work quickly because with increasing time, it becomes challenging to both sets and mixes the cement. 
• If you don’t get rid of the heat in your cement, there might be cracks in the cement after the process of setting has been completed. 
• Lastly, quick-setting cement is not readily available in the market, and on top of that, whatever is known, is quite pricey. 

Uses Of Quick-Setting Cement:

The uses of quick-setting cement are as follows,

• The quick-setting formulation of cement can be used for any underwater construction.
• The quick-setting formulation of cement is also used for constructions in both cold and rainy areas where quick strength is required over a short time period.
• Thirdly, it can be used in areas experiencing high-temperature conditions where water evaporates rapidly.
• Quick-setting cement is also used for fixing steps made from concrete.
• Lastly, quick- setting formulation of cement is used for anchoring rock bolts inside tunnels and other similar underground structures.

Basically, quick-setting cement is used when quick setting is required. You can get it by adding a small percentage of aluminum sulfate and then finely grinding it to become cement. Furthermore, for the quick-setting action to take place, the cement mixture also contains a small percentage of gypsum and retarder. Here, the addition of the aluminum sulfate helps accelerate the setting fast. 

Basically, when you mix quick-setting cement with water, it sets in five minutes. Within 30 minutes, you will find it becoming hard like stone. 

What are the Major Properties of Quick-Setting Cement? 

The following are some of the major properties of quick-setting cement that make it a better choice for construction: 

• As compared to other variants of cement, quick-setting cement has a brownish and yellowish appearance. 
• After the mixing and application of the cement, it is easily able to withstand harsh weather conditions for a longer period of time. 
• Such cement works great with different types of materials like metals, concrete, brick, wood, and plastic. 
• It takes five minutes to start the hardening process of quick-setting cement. It will start instantly after you put the cement together. Hence, you will need to be careful with the cement and ensure quick application. 
• There are good waterproofing properties of quick-setting cement. Hence, it acts as a great hardening material, which helps in underwater construction. 
• It takes 28 days for concrete built with a quick-setting cement to reach its final mechanical resistance. 
• The quick-setting cement has applications both in interior and exterior spaces. 

Major Applications of Quick-Setting Cement 

The following are some of the major applications of quick-setting cement that you need to know: 

Fast Repairs 

Regular cement takes hours to set and becomes hard. Hence, it is not the ideal option if you want faster construction and repairs. If you need a speedy fix, the best option for you to consider is quick-setting cement. For example, quick-setting cement helps a lot in repairing cracked floors, roads, bridges, building repairs, etc. 

Underwater Construction 

Due to the lack of density and the washout effect of water, it is hard for regular cement to properly settle underwater. However, with quick-setting cement, performing repairs and construction below the waterline is much easier to do. 

Cold Weather Work 

When the temperature is on the lower side, it takes a longer time for regular cement to set in. However, since quick-setting cement sets faster, it is a great option for construction projects that happen in cold weather. It is also a great option for building foundations of buildings and slabs. 

Rapid Set Applications 

If you need faster construction, there is hardly any better option than quick-setting cement. It also helps in the construction of prefabricated concrete.  

Grouting and Securing 

The fast-curing properties of quick-setting cement make it a valuable option for applications in anchoring and grouting. Furthermore, when you are installing bolts, dowels, and other fasteners in concrete, the best thing to use is quick-setting cement. Moreover, rapid setting also helps in the grouting process. 

The Quick Cement Phenomenon: Is It Good To Use?

As the name of the cement is indicative, quick-setting cement is commonly utilized for construction whenever a situation of a fast-setting process is necessary. Quick setting cement is produced by adding a tiny portion of alumina to delicately ground clinkers of cement and, in the prodess, decreasing the quantity of calcium sulfate or gypsum. 

The grinded clinkers combined with the aluminum sulfate are responsible for speeding up the cement setting time. As a result, quick-setting cement has a very fast setting time compared to ordinary Portland cement. 

It is the aluminum sulfate that is responsible in turn for speeding up the hydration rate of tricalcium silicate (C3S) and Tricalcium aluminate (C3A) in the cement – this subsequently leads to the development of strength and fast evolution of heat. Thus, aluminum sulfate is a catalyst in the hydration process of Tricalcium silicate (C3S) and Tricalcium aluminate (C3A).

The cement’s usage, of course, depends on your requirement and also to an extent on your budget and the cement’s availability. But, of course, it is suitable for use where you know that the work will happen quickly since the setting time is between 5 to 30 minutes on average. Also, keep in mind that it’s challenging to find and expensive to buy.
