What Is Cement Slurry? Hunker

Cement slurry has been in use since ancient times and continues to be one of the most durable types of foundation materials used in construction around the world. Its basic mixture is a fine sand with cement and water added until the entire mixture is a thick, creamy batch of concrete that can be poured through a tube or down a chute, such as on the back of a concrete truck.

Cement composition and classification - PetroWiki

25/06/2015  Almost all drilling cements are made of Portland cement, a calcined (burned) blend of limestone and clay. A slurry of Portland cement in water is used in wells because it can be pumped easily and hardens readily, even under water. It is called Portland cement because its inventor, Joseph Aspdin, thought the solidified cement resembled stone quarried on the Isle of
