Hardening Accelerating Admixture Early Strength Agent for Concrete

It is a liquid admixture to be added to the concrete during the mixing process. Enough mixing time to secure homogeneous dispersion should be provided. Based on ptma hardening accelerating agent, the growth of the essential Calcium Silicate Hydrate crystals is strongly accelerated and  boost the hydration process of early age cement within 24 hours(especially 6-12 hours).

Uses  

This ptma hardening accelerating admixture is  optimized for all kinds of concretes, especially for structural precast elements where high early strength development is a key success factor for the producer.

Dosafe : recommended dosage is 2.0 ~ 6.0 % by cement weight ,it is advisable to make trial mixes

before used. The dosage is not absolute limits, other dosages may be utilized in special cases

according to specific job conditions.

This admixture should not be pre-mixed with other admixtures. If other admixtures are to be used in concrete containing they must be dispensed separately.

Benefit   

  • Promotes concrete hardening at low, ambient and even heat curing temperatures.

  • Increased production cycles

  • Better use of formwork by earlier demoulding

  • Reduced running cost of curing

  • Allows use of minimum required cement quantities

  • Allows   binder  optimization by   using   lower   grade,  less clinker-containing    cements     or  by  increasing    use   of supplementary cementitious materials (Limestone, Fly Ash, Slag)

  • Lower risk of delayed ettringite formation

  • Reduced water absorption      

  • Improved concrete durability

  • Improved plant and product ECO-efficiency by reducing CO2 emissions
