MarkPlast Conretard 348
MARKPLAST CONRETARD 348 is a high performance retarding plastiser for conrete which maintian good workability especially in high ambient temperature. The retarding admixture is used in structural and mass concrete.
Specification Compiles
- ASTM C494 TYPE B and D
- Considerably improves the cohesion of concrete, reducing segregation and bleed water of particular use where fine aggregates of poor grading and particle shape are evident
- Reduces placing problems in hot weather, through improved workability and workability retention
- Improves surface finish
- Improves trowellability
- Reduces honeycombing/cold joints effect
- Improves pumpability of concrete
- Reduces effects of various modes of attack on concrete and embedded steel through considerable reduction in permeability
- Reduced shrinkage and creep
- It does not contain Chlorides hence does not corrode the reinforcements.
- Elimination of vibration and reduced the labor cost in placing by implementing self-compacting concrete
- It donot contains chlorides or other ingredients promoting corrosions and steel reinforcement.Hence suitable for reinforced concrete structures
- Large volume pours
- Avoidance of ColdJoints
- Construction joints without formwork
- Long hauls
- Elevated temperatures
- Re-vibrated concrete
- In hot weather concreting where delays to initial and final set are important and where maximum slump retention is of concern – such as site batched, precast, and ready mixed concretes
