MasterLife SRA 50 – A expanding plasticising admixture for cement, grout and concrete

Description

MasterLife SRA 50 is an expansion system, which compensates for plastic shrinkage and settlement in cementitious grouts. Supplied in powder form, MasterLife SRA 50 produces controlled expansion in cement grouts and maintains high water retention. 

It contains a water-reducing agent, which increases the workability of the mix with reduced water content, making a stronger grout. Full expansion is achieved before initial setting occurs resulting in a high degree of interfacial contact.

Where is MasterLife SRA 50 applied?

For bedding, jointing, duct grouting and void filling applications where the following characteristics are beneficial: 

• A cement plasticising and water-reducing agent to improve the free flowing properties of the grout at low w/c ratios 
• An expanding agent that increases the volume of the grout, which in turn eliminates shrinkage and settlement 
• A catalyst to control the rate of expansion and to ensure full expansion of the grout.

MasterLife WP 707M – Low dosage, liquid, integral waterproofer 

Description

A liquid admixture to give high water resistance, based upon a blend of specially selected surface active agents and refined lignosulphonate. Waterproof concrete is the result of good concrete practice coupled with the lowest w/c ratio compitable with achieving full compaction. 

The use of MasterLife WP 707M enables all these criteria to be met due to its strong plasticising and water-reducing properties. 

Where is MasterLife WP 707M applied?

MasterLife WP 707M should be used in all structural concrete that is constantly or intermittently in contact with water, such as sea walls, tunnels, basements, structural and pre-cast concrete in exposed superstructures.  

What are the advantages of MasterLife 707M?

• Concrete containing MasterLife WP 707M is resistant to water penetration either under conditions of hydrostatic pressure or capillary absorption 
• Durability is increased due to significant reduction in w/c ratio 
• Sulphate attack is reduced due to the sulphate bearing ground water being resisted 
• The cohesive properties of the concrete are improved, thus reducing segregation and bleeding 
• Concrete of similar workability to a control mix produced with MasterLife WP 707M is easier to place 
• Pumpability of concrete is greatly improv​

MasterLife WP 730

A hydrophobic pore-blocking ingredient for watertight concrete 

Description

MasterLife WP 730 is a hydrophobic poreblocking ingredient (H.P.I.) for concrete. It significantly reduces water absorption of concrete. 

MasterLife WP 730 is a chloride free organic admixture and supplied as a colourless, clear to slightly cloudy viscous liquid. It reacts with the cement hydration process to form a hydrophobic ingredient to reduce the capillary suction and prevent the ingress of potentially deleterious soluble material, resulting in concrete with enhanced durability. 

Where is MasterLife WP 730 applied?

MasterLife WP 730 is suitable for any concrete structure, which requires watertightness, such as:

• Basement walls and floors
• Tunnels / underpass
• Foundations, piles and pile caps
•  Water retaining structures, swimming pool, water tanks, reservoirs, water towers
•  Land drainage, manholes
• Reinforced concrete in marine environment subject to tidal and wet / dry cycling
•  Waste water treatment and desalination plant 

What are the advantages of MasterLife WP 730?

• Very low water absorption
•  Increased durability and water tightness 
• Integral system Protection is maintained throughout the concrete matrix 
• Ammonia free 
• Environment friendly 
• Fully compatible with certain surf

MasterLife CI 222 – Organic corrosion inhibiting admixture

MasterLife CI 222 is a state-of-the-art corrosion inhibiting admixture formulated to inhibit the corrosion of steel reinforcement in concrete. 

MasterLife CI 222 provides two levels of corrosion protection, inhibiting and waterproofing making it the most effective corrosion inhibiting admixture available. 

What are the advantages of MasterLife CI 222?

MasterLife CI 222 extends the service life of reinforced concrete by slowing the ingress of chlorides and moisture into the concrete and by forming a strong, durable protective film on the reinforcing steel for a second level of corrosion protection. 

This dual mechanism system makes MasterLife CI 222 effective with all cement factors, as well as in cracked concrete where the elements that cause corrosion have direct access to the reinforcing steel.
