essentially the same as the one used today, early cements lacked crucial additives.[3] Additives are, chemical compounds that are added to basic cement components in order to tailor the cement to specific down-hole temperature and pressure conditions.[3] Without these additives, basic cement often failed to harden and form an effective plug.[3]

Type SA, or Special Air-Entraining lime, is a type S hydrated lime containing an air-entraining additive. These products must entrain between 7% and 14% air when mixed with cement and sand in mortars. If mixed in a Type M mortar or utilized in a structural reinforcement application, the air content of the mortar cannot exceed 12%.

The invention discloses a lightening admixture. The lightening admixture is characterized in that a main ingredient is a high-molecular polymer; the density of cement paste can be reduced to 1.78-1.15 g/cm<3> or less when the mixing quantity is 1-200% of the amount of cement. Compared with the prior art, the lightening admixture has the advantages that …
Weighting agents () are added to increase the density of the cement. They are typically used to combat high bottom hole pressures. Common additives are powdered iron, ferromat, powdered magnetite, and barite. Hematite can be used to increase the density of a mixture up to 2200 kg m −3 (19 lb/gal).
