RMC (Reinforced and Mass Concrete)


RMC SUPER 808

HIGH PERFORMANCE SUPERPLASTICISER FOR SLUMP RETENTION AND HIGH STRENGTH CONCRETE


INTRODUCTION:

RMC SUPER 808 is a chloride free superplasticizing liquid admixture based on selected lignosulphonates.


USES

  • To improve the effectiveness of the water content of a concrete mix.
  • To help improve the workability of site mixed concrete without increasing water demand. To extend working times of concrete. To provide excellent slump retention properties in tropical conditions.
  • May be used in bridge deck concrete to extend the time of set. This is especially important when the length of placement may result in flexural cracks created by dead load deflections during placement.
  • To provide improved durability by increasing ultimate strengths and reducing concrete permeability.
  • Suitable for high strength of concrete.


ADVANTAGES

  • Controlled retardation extends working life and stiffening time for ease of construction.
  • Control of stiffening improves slip forming and assists in preventing the formation of cold joints in large pours.
  • Water reduction significantly improves compressive strengths at all ages and enhances durability.
  • Slight air entrainment improves cohesion in mixes with poorly graded sands or a lack of fine material, minimizing bleed and segregation.
  • Minimizes transportation delay problems and maintains ease of pouring and reduces the risk of pump blockage.
  • Allows specified strength grades to be met at reduced cement content or increased workability.
  • Chloride free, safe for reinforcement bars allowing use in prestressed and reinforced concrete.


STANDARDS COMPLIANCE

RMC SUPER 808 is produced to conform with:

  • BS 5075 Part 3,
  • ASTM C494 as Type B, D and Type G


TECHNICAL DATA

  • Appearance: Brown solution
  • Specific Gravity: 1.19
  • Chloride Content: Nil
  • Dispersion: Instantly disperses in water
  • Hydration: Delays hydration of the cement
  • Fire Hazardous: Water based-nonflammable.

DOSAGE

Dosage under a particular situation can vary between 0.70 to 1.50 litres per 100 kg of cement. The following data may be found useful by the end user, but it is highly recommended that on site trails are conducted prior to use of the product. 1] The level of retardation obtained may be varied by altering the dosage of RMC SUPER 808 used, which will also alter the level of water reduction obtained. 2] Retardation is also affected by products and factors other than the admixture, depending on the mix details and conditions involved. Products include the type of cement, aggregate, sand and water. Major factors which will effect retardation are the dosage, high temperatures, changing in cement content, amount of tri-calcium in the cement and the use of combination of admixtures in the same concrete mix. 3] RMC SUPER 808 is suitable for use with all types of Portland and Sulphate Resisting cements. 4] The correct quantity of admixture should be measured and be added to the concrete with the mixing water. 5] Do not overdose. Over dosing may have adverse effects on the final strength of hardened concrete.


STORAGE

When RMC SUPER 808 is stored under shade within an ambient temperature range of 5°C to 50°C. The shelf life of the product is 12 months.


PACKING

RMC SUPER 808 is supplied in 210 litre drum.
