Accelerset
Description:
Cemix Accelerset is a calcium chloride based accelerator used with Portland Cement mortars, renders and concrete where acceleration of the set and high early strength development is required.
Typical Applications & Uses:
Cemix Accelerset is ideal for use when concrete has to be laid when limited time is available for the completion of the work. The addition of Cemix Accelerset to Portland Cement mixes speeds up the rate at which the mix sets and hardens, gives a high early strength development and increases the density of the mix. These improvements in performance mean that formwork may be stripped earlier than normal.
The use of Cemix Accelerset improves the abrasion resistance of concrete mixes, makes them less porous and reduces the danger of surface dusting. Portland Cement mixes containing Cemix Accelerset may be used for:
• Cold weather concreting
• Industrial flooring
• Machine bases and pits
• Sea defence work
• Road repairs
• Precast work giving faster mould turn around. Earlier stacking reduces storage space.
Advantages:
• Accelerates setting time of Portland cement mixes.
• Speeds the hardening rate of Portland cement mixes.
• Increases the density of Portland Cement Mixes.
• Makes concrete less porous.
• Gives high early strength.
• Improves abrasion resistance.
• Reduces dusting.
