Concrete Construction Admixtures

Product Details:

Usage:

• To produce pumpable concrete.
• To produce high strength, high grade concrete by substantial reduction in water resulting in low permeability and high early strength.
• To produce high workability concrete requiring little or no vibration during placing.

Product Details:

Uses:

• To minimise permeability and increase the waterproofing properties of concrete and cement sand mortars for critical applications like roof slabs and screeds, basements, external plastering, bathroom floors, water tanks, sumps, drains etc.

Advantages:

• Liquid admixture: Instant and complete dispersion throughout the mix. Uniform waterproofing throughout concrete matrix.
• High efficiency: Dramatic reduction in permeability of concrete/ mortar.
• Improved workability: Improves compaction of concrete and mortar, even where harsh sands or aggregates are used.
• Improved concrete quality : Minimises porosity and honey combing. Produces dense homogenous concrete.

Standards Compliance:

• Conplast WL conforms to IS:2645-2003.

Description:

• Conplast WL is based on lignosulphonates which mixes readily with water and therefore disperses evenly. 
• Conplast WL waterproofs by improving the quality of the concrete or mortar. 
• It reduces the water demand for required workability and minimises segregation and bleeding. 
• Thus it is more efficient compared to traditional powder waterproofers as its use results in two fold improvement of concrete or mortar.

Properties:

• Chloride content : As per IS:2645-2003
• Compatibility : Can be used with all types of cements,including pozzolanic but not High Alumina Cement.
• Permeability to water : Less than 15% as compared to 50% max. allowable under IS:2645compared to control sample.
• Setting Time: No significant effect on setting time of concrete or mortar.
• Compressive Strength : Maintains compressive strength equal to control concrete or mortar and can even improve on strength property if full advantage of water reduction potential is utilised.
• Workability: Improves workability at reduced water cement ratio

Application instructions:

• Mortar: Conplast WL is ideal for use with all sand/cement mortars where it is required to reduce permeability to a minimum.
• Concrete: Conplast WL is recommended for all general mass concrete work where, due to harsh aggregates, difficulty of compaction or mix control, the risk of porosity and permeability must be minimised. Eg. Basements, bund walls, tanks, balcony, floor and roof slabs.
• N.B.: The minimum dosage is 125ml and the maximum is 200ml per 50kgs of cement. If maximum dosage is used a minimum of 15% water should be reduced to ensure no loss in strength. Site trials shall be carried out to arrive at the optimum dosage.
• The required quantity of Conplast WL is measured and stir into the first or second bucket of water
• Conplast WL water mixture shall be added to the concrete or mortar and mixed thoroughly.
• Mixing shall be continued and further water shall be added until the required workability is obtained.

Product Details:

Uses:

• To provide excellent acceleration of strength gain at early ages and major increases in strength at all ages by significantly reducing water demand in a concrete mix. ! Particularly suitable for precast concrete and other high early strength requirements. ! To significantly improve the workability of site mixed and precast concrete without increasing water demand. ! To provide improved durability by increasing ultimate strengths and reducing concrete permeability.

Advantages:

• Major increases in strength at early ages without increased cement contents are of particular benefit in precast concrete, allowing earlier stripping times.
• Makes possible major reductions in water:cement ratio which allow the production of high strength concrete without excessive cement contents.
• Use in production of flowing concrete permits easier construction with quicker placing and compaction and reduced labour costs without increasing water content.
• Increased workability levels are maintained for longer than with ordinary sulphonated melamine admixtures.
• Improved cohesion and particle dispersion minimises segregation and bleeding and improves pumpability.
• Chloride free, safe for use in prestressed and reinforced concrete.

Product Details:

Uses:

• To produce pumpable concrete
• To produce high strength, high grade concrete by substantial reduction in water resulting in low permeability and high early strength.
• To produce high workability concrete requiring little or no vibration during placing.

Advantages:

• Improved workability - Easier, quicker placing and compaction.
• Increased strength - Provides high early strength for precast concrete if water reduction is taken advantage of.
• Improved quality - Denser, close textured concrete with reduced porosity and hence more durable.
• Higher cohesion - Risk of segregation and bleeding minimised; thus aids pumping of concrete
• Chloride free - Safe in prestressed concrete and with sulphate resisting cements and marine aggregates.

Product Details:

Uses:

• Conplast SP430 SRV is used where a high degree of workability is required and also as an aid to workability retention where delays in transportation or placing are likely or when high ambient temperatures cause rapid slump loss. To facilitate production of high quality concrete of improved durability and water tightness.

Advantages:

• Speeds Construction : Increased workability reduces placing time, equipment and labour element.
• Self Compacting : Conplast SP430SRV modified concrete is highly fluid and needs little or no compaction.
• Reduced Permeability: Better dispersion, reduces porosity and improves water penetration resistance.
• Reduced Segregation: Increased cohesion minimises segregation and bleeding, improving surface finish.
• Longer Placing Time: Conplast SP430SRV gives greater usable life of concrete at high ambient temperatures because of its unique workability retention potential.
• Improved Pumpability: Increased workability and cohesion aids pumping by reducing line friction, dry packing and slump loss due to temperature.
• Chloride Free: Safe in prestressed, reinforced or marine concrete and compatible with sulphate resisting cement or marine aggregate.
