Enhanced Structural Integrity:Innovative Concrete Admixtures for Deep Foundation Construction
Enhanced structural integrity:Innovative concrete admixtures for deep foundation construction
The standard procedure in deep-foundation construction uses bored concrete piles or pile walls. In unstable ground condi-tions, or where the ground is prone to subsidence, this serves
to reliably distribute structural loads onto a suitable bearing stratum.
Toensuresufficientstructuralintegrityandmaximumdurabilityof the foundation, the concrete used in the construction of boredpileshastomeetavarietyofflowabilityandstabilityrequirements.TheinnovativeconcreteadmixturesofferedbyMaster Builders Solutions are perfectly geared to such requirements.
The combined use of the latest generation of plasticizers (MasterSure LDP) and stabilizers (MasterMatrix FC 500) in deep-foundation construction enables groundbreaking synergyeffectswhererheologyandwaterretentionare concerned:
Your benefits:
Excavation of diaphragm wall /
bored pile, including any required piping
Installation of reinforcement
cage
Concreting of bored pile through tremie pipe using a hopper, starting at the base of the borehole
As per project specifics,theinsertion of
reinforcement cage may be required subsequent to
concreting
Removal of segmental pipes as
concreting progresses
Concreting of bored piles using the tremie method
Extremely low concrete viscosity for easy pumping
Maximumflowabilityinself-compacting concretes
Effectivewaterretention
Robust, high-performance concrete
Highly extended workability time of 6 hours or more
Innovative Concrete Admixtures for Deep Foundation Construction
MasterSure LDP (Long Distance Pumping) is an innovative plasticizerwhoseuniquepolymerconfigurationwasspeciallydeveloped for the highly demanding requirements of deep-foundation construction. In the production of high-performance concretes at low water / cement ratios, MasterSure LDP technology combines extended consistency retention with out-
standing rheological properties. This enables maintaining a uniformconsistencyinflowableconcretesforsixhoursormore at very low viscosity levels. This way, the concrete remains workable and stable throughout long transportation and pumping distances.
Your benefits:§Significantlyextendedworkabilitytimeassistsverytallbored

§ Viscosity reduction by up to 50% for better pumpability across greater distances and faster concrete placement§ Supports low water/cement ratios without increased
stickiness

Enhanced structural integrity:Innovative concrete admixtures for deep foundation construction
Developed by the experts from Master Builders Solutions, MasterMatrix FC 500 is a novel stabilizer for use in deep-foundation operations. The high hydrostatic pressure during the concreting of bored piles (up to 70 m) can, for instance,
result in water being pressed out and therefore resulting in reduced-quality bored piles. MasterMatrix FC 500 prevents this, by combining maximum water retention with low viscosity and good temperature stability.
Your benefits:§ Excellent water retention that segregation and bleeding

§ Very good workability, irrespective of mixing intensity or head of pressure§ Optimum temperature stability to support changes in
