Hanson 40N Concrete Maxipack

DESCRIPTION

Hanson 40N Concrete (C32/40) is prepared by blending Hanson Cement CEM I 52.5N, with Regen

GGBS and aggregates (0/4mm sand and 4/10mm coarse aggregate). The blend of CEM I and GGBS

produces the cement combination CEM III/A+SR which enhances sulfate resistance.

 

The mix proportions are designed to achieve a mean strength in excess of 40N when the product is

mixed to a target consistence of S2 (50-90 mm slump).

 

Hanson 40N Concrete has been designed to meet requirement of BS 8500 Concrete, but conformity

cannot be attributed to this Standard since conformity is based upon the performance of the mixed

concrete. To establish conformity, on-site testing of the mixed concrete is required.

 

APPLICATION

Hanson 40N Concrete can be used for a whole range of building projects requiring a concrete with

high compressive strength.

 

BENEFITS OF USE

The benefits of Hanson 40N pre-packed concrete include:

• Enhanced sulfate resistance

• Reduced chloride penetration, improving protection of embedded steel reinforcement.

• Prevents damaging alkali silica reaction

• Prevents delayed ettringite formation

• Easy to use, just add water

• Saves time, quick and convenient

 

INSTRUCTION FOR USE

All surfaces to be worked should be free from oil, grease and any loose material. The area where

concrete is to be placed should be prepared to prevent loss of moisture from the wet concrete.

For best results, mix thoroughly using a mechanical mixer, empty the bag of Hanson 40N Concrete

into the mixer and blend until uniform. Slowly add clean water until the desired consistency or slump

characteristics are achieved.

Alternatively, empty the bag of Hanson 40N Concrete onto a clean, flat moisture resistant surface,

such as a mortar tray. Slowly add clean water until the desired consistency or slump characteristics

are achieved, by thoroughly mixing with the aid of a shovel or similar.

Please note: The contents of the bag may segregate during transport and handling. To ensure

satisfactory performance, the entire contents of the bag should be mixed thoroughly. If only part of

the bag is required at a time mix together the entire contents on a clean, dry surface. Return surplus

to the bag or other suitable container.

Avoid adding too much water whilst mixing as this will weaken, affect the setting time, and affect the

durability of the concrete mix.

For best results, use the concrete within 30 minutes of mixing with water. Protect newly laid concrete

from the weather until fully hardened. Concrete strengths are improved by keeping the concrete damp

during hardening.

Application temperature: +5°C to +35°C.Application temperature: +5ºC to +35ºC.
