Extenders allow the production of a greater volume of slurry from the powdered cement. This feature can result in reduced cost and, where the extenders are lightweight (or they allow additional water to be used), lower density. The advantage of reduced cost is obvious. Reduced density is important where weak formations are to be cemented. Such weak formations could part and allow loss of the slurry during the cementing operation. A variety of oil and gas cement extenders are available to provide for different requirements of lower density, lower cost, and other performance parameters.
How do Cement Extenders Work?
A cement extender is a chemical additive used to increase the volume of the slurry or can be used to decrease the density of the cement. The additive is mixed into the cement slurry and finds the free water within the mix. The faster the water gets absorbed the faster the cement will be curated. Extenders also increase a normal batch of cement which typically be what your business producing a bigger yield of cement with a faster cursing time.
Why do we use Cement Extenders?
Many business owners constantly have short jobs that need quick turnarounds within the project. Speeding up the thickening time also allows the extenders to find weak formations within the concrete thus also offering better compression strength for cement slurries. Extenders also increase the yield and volume of the cement slurries; so many business owners understand that an increase in product means you can produce more with less cost.
Advantages and Disadvantages of using Cement Extenders?
There are many advantages to using cement extenders. Cement extenders can be used to decrease the density of the slurry. Cement extenders can also improve the durability of the concrete once it is hardened. One of the disadvantages is that some extenders are not compatible with other additives.

At Petrochem, our cement extenders were created to save time with a faster thickening time for cement slurries. The additive is combined within the slurries, finds the free water, and strengthens the compression of the overall concrete. Our extenders also can find weaknesses within the curated cement and strengthen those components. Contact a concrete additive supplier specialist today to learn about all the different types of cement expanders Petrochem offer and how we can make curating cement easier for the oilfield drilling industry.
