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.
SSCC with its three son-companies provids you a whole series of assorted services, including drying cement blend, testing the cement, designing and manufacturing cementing accessories, storing and transporting the bulk cement, developing cement additives series, supplying materials, etc. Our
Cement and Cement Additives In everyday life, cement is the element that makes concrete strong so it can support heavy weights and hold back powerful forces. In the oil industry, cement by itself does the same sort of thing. It supports heavy steel casing downhole. Cement forms a strong, effective seal that can hold back formation pressures
[Well Completions] Chemicals and materials added to a cement slurry to modify the characteristics of the slurry or set cement. 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.
Mapei is extending the production of its cement additives with its introduction of the C-ADD (Cement ADDitives) Division to the Americas. The cement additives being introduced in North America include cement additives, strength enhancers, and dust-control technology for all types of cement, as well as air-entraining and waterproofing additives for masonry cements.
Oilfield Cementing Additives & Chemicals Function: Efficient dispersant in low-weight fresh water muds used in up hole drilling and effective additive for treating cement contamination and reduce viscosity. CITRIC-ACID (Download CITRIC-ACID Technical Data Sheet) Description: Citric Acid for Cement Contamination. Function: Reduce pH and removes calcium to pretreat or remedy cement
Cement additives can be helpful to overcome these issues, but the benefit of strength enhancers is limited. Performance enhancers such as SikaGrind LS can extend the content of limestone in PLC, due to their impact on cement properties and cement production.
Equipment. We develop innovative and fit-for-purpose cementing equipment complemented by technologically-advanced, proprietary cement blends and chemistry. Our cementing equipment features climate controlled, enclosed operator cabs, mass flow meters, re-circulating mixers and DAS (data acquisition systems) that record all job parameters in real
Operators select cement systems on the basis of job objectives and well requirements. Cement is basically inelastic. Cementing systems are similar in many ways. These systems vary, however, in
Cement additives are mainly dosed onto the clinker belt close to the inlet of the mill. Frequently, the clinker is hot and parts of the cement additive evaporate (as can be seen in Figure 1). Therefore, good ventilation must collect the evaporating gases and/or respiratory protective equipment should be used. Alternatively, the cement additive
Well cementing is the process of introducing cement to the annular space between the well-bore and casing or to the annular space between two successive casing strings. Personnel who conduct this job are called "Cementers".

Concrete production is the process of mixing together the various ingredients—water, aggregate, cement, and any additives—to produce concrete. Concrete production is time-sensitive. Once the ingredients are mixed, workers must put the concrete in place before it hardens. In modern usage, most concrete production takes place in a large type
