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.

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
