Shorten setting times and improve slurry properties
Cal-Seal 60 accelerator provides operators with important advantages during remedial work. Cal-Seal accelerator uses a hemihydrate form of calcium sulfate to help accelerate Portland cement, control lost circulation, act as an expanding aid and impart thixotropic properties to cement slurries. Cal-Seal accelerator increases viscosity and ‘early strength’ of slurries while using more water than other accelerators. Cal-Seal accelerator also decreases slurry density, thickening time and overall ‘final strength’.
When blended with Portland cement, Cal-Seal 60 accelerator is perfect for shallow wells and for surface applications that require short setting times and rapid strength development. Cal-Seal 60 accelerator is effective at temperatures between 40° and 170°F (4° and 66°C), and mixing small amounts of sodium chloride (NaCl) to Cal-Seal 60 accelerator can help enhance cement acceleration in low temperatures.
Accelerator concentrations can vary between 5% to 90% by weight of cement (bwoc) to meet specific requirements and conditions.
Cal-Seal 60 accelerator can provide the following benefits:
Within 60 minutes, slurries containing Cal-Seal 60 accelerator can withstand pressures exceeding 2,600 psi.
Cal-Seal 60 accelerator has a shelf-life of up to 24 months.
Cal-Seal 60 accelerator is environmentally safe and is not classified as a hazardous waste by the Environmental Protection Agency.
