Construction Admixture

Product Details:

Uses:

As an accelerator for use in concrete and cement mortar to give rapid strength development for early stripping of formwork and to help resist the effects of frost. Ideal for winter working

Advantages:

·         Allows continued placing of concrete at low temperatures.

·         Gives additional frost protection by reducing the low watercontent and accelerating hydration of cement

·         Enables earlier release from precast moulds thusspeeding production

·         Reduces the water content of concrete or mortar withoutloss of workability

·         Reduces segregation and increases density andcompressive strength

·         Accelerates the hardening of floors and screeds.

Standard compliance:  CX FASTSET AC complies with BS 5075 Part 1 and ASTM C494, Type C.

Description:

CX FASTSET AC is supplied as a light yellow to white liquid. When added to cementitious mixes it accelerates hydration and enables the water content to perform more efficiently by dispersing agglomerated cement particles. This further improves strength by enabling water reduction to be made at constant workability. Where there is embedded or prestressed steel or where sulphate resistant cement is used or when steam curing is employed, CX FASTSET AC should be replaced by CX FASTSET AN chloride free accelerating concrete admixture.

Properties:

• Specific gravity : 1.30 - 1.31 at 30⁰C
• Chloride content: At the maximum recommended rate of addition, 3.4 liters/100 kg of cement, the Chloride ion concentration is 0.9% by weight of cement. In unreinforced concrete containing no embedded metal, CX FASTSET AC, at the recommended dosage rates may be used.
• Air entrainment: General less than 1% additional air.
• Compatibility with other admixtures: CX FASTSET AC is compatible with other CHEMAX admixture but should be added separately to the mix. Reduced air content may result when CX FASTSET AC is used in conjunction with some air entraining agents. Consult CHEMAX  if other admixtures are to be used.
• Compatibility with other cements: CX FASTSET AC is compatible with ordinary and rapid hardening Portland cement but not high alumina or sulphate resisting cements.
• Workability: The addition of CB FASTSET AC without reduction of the water content increases the slump and significantly improves concrete flow characteristics without decrease in concrete strength.
• Setting times :  Typical results using CX FASTSET AC are given in Table 1.
