Range For Compressive Strength In Barite

They are used to reduce the slurry density in case when there is a risk of exceeding the fracture pressure of some formations.The use of this type of additives can also reduce the compressive strength and increase the thickening time.They called extenders because they allow more mix-water and as a consequence more slurry volume.
