What are Concrete Additives? Why do we use them? Big D

02/02/2018· Accelerating Additives They accelerate the rate of cement hydration. These additives are most efficient during the cold seasons. Calcium chloride is used as the accelerating additive on non-reinforced concrete. Air-Entrainment. These additives are used to introduce microscopic air bubbles to stabilize the concrete. The resultant effect is preventing the concrete from cracking in a cold

Cement Additives (function and definition) Planning

Fluid loss control additives are added to cement slurries for the following reasons: To reduce the possibility of dehydration opposite porous zones and consequently flash setting of the cement. Loss of fluid from the slurry will result in increasing slurry viscosity and gradient and higher circulating pressures. Excessive fluid loss will reduce slurry volume and give less cement fill. When

cement additive Oilfield Glossary

Cement additives may be broadly categorized as accelerators, retarders, fluid-loss additives, dispersants, extenders, weighting agents, lost circulation additives, and special additives designed for specific operating conditions. Cement additives are commonly available in powder or liquid form, enabling some flexibility in how the cement slurry is prepared.

Additives, Chemicals, Materials Halliburton

Additives are chemicals and materials blended into base cement slurries to alter the performance of the cement. Due to the inherent nature of base cements (Neat, Portland and Pozzolanic) and because of the demands placed on the cement sheath throughout the life of the well, the performance properties of the cementing slurry are modified to address the specific and unique conditions of each well.

Portland cement Wikipedia

Portland cement was developed from natural cements made in Britain beginning in the middle of the 18th century. Its name is derived from its similarity to Portland stone, a type of building stone quarried on the Isle of Portland in Dorset, England.. The development of modern Portland cement (sometimes called ordinary or normal Portland cement) began in 1756, when John Smeaton experimented with
