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:

• It is based on lignosulphonates which mixes readily with water and therefore disperses evenly. 
• It 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.

Fosroc Cebex 100 Plasticised Expanding Grout Admixture, a plasticised expanding grout admixture is supplied as a powder. The material is a combination of a plasticising agent and a gas producing expansion medium. The plasticising agent allows the use of a reduced water/ cement ratio with consequent increased strengths and durability. The expansive medium counteracts the natural settlement and plastic shrinkage of the grout and aids stability and cohesion.

Uses:

Cebex 100 is an admixture for cementitious grouts where a reduced water/cement ratio and positive expansions are required. Applications include bed grouting, duct grouting, non-shrink infilling and jointing.

Advantage:

• Gaseous  expansion  system  compensates  for  plasticshrinkage  and  settlement  in  properly  designedcementitious  grout.
• Reduced water/cement ratio mixes in the grout mix ensure slow permeability and long term durability in service.
• Gives grout high fluidity with low water/cement ratio, thusmaking placement or injection of the grout easy.
• No metallic iron content to corrode and cause staining ordeterioration due to rust expansion in the grout.
• Composition  allows  high  early  strength  development  ingrouts, without  the  use  of  chlorides.

Cebex 112 is supplied as an off-white to pale yellow liquid which mixes readily with water in any proportions. It is based on internationally recognised chemicals and is  free from calcium chloride and similar salts.

Uses:
To improve workability and trowelling properties of sand/ cement mortar mixes during application. To increase quality of  masonry  and  plastering.

Advantage:

• Improved moisture retention and bond strength:  Slows down drying out of mortar which remains workable longer. Ensures better bond to all surfaces, including ceiling.
• Makes mortar crack resistant:    Minimises drying shrinkage cracks and  increases frost resistance in cold climates.
• High workability: Even with harsh sands, makes creamy easy-to-apply  mortar.
• Cost saving: Increase yield of the same quantity of sand/ cement. Extra coverage normally exceeds material costs.
• Better & safer masonry: Mortar fills joints easily and efficiently and ensures stronger construction.
• Improved appearance: Mortar cuts cleanly from faces of brick, block or stone work.
• Increased productivity: Speeds up  work by easy application of mortar.

Conplast NC is guaranteed completely free of all forms of chloride and is supplied as a light straw coloured liquid. The main active ingredient is an inorganic formate.


Uses:

• To accelerate the setting and early strength gain of Port land cement  concrete and mortar mixes without the introduction of chloride.
•  Acts as a plasticiser, so gives significant increases in both ultimate and early strengths.    
• Typical applications include precast concrete, concrete placed in coldweather, concrete for repairs, mortars for brickwork.

Advantage:

• Chloride free, safe in pre stressed and reinforced concrete
• Produces exceptionally high early strengths
• Plasticising action gives increased workability and/ or increased strengths
• Early setting improves frost resistance
• Suitable for brick laying mortar mixes
• Particularly effective in concrete at low temperatures

Sprayset HBL (M) is a chloride free liquid based on a blend of inorganic powders, which is added to a sprayed concrete mix to impart properties of high build and low rebound.

Uses :

• It is added to a sprayed concrete mix to impart properties of high build and low rebound to enable a high build of sprayed concrete, shotcrete and gunite without slump and provide set acceleration and reduce rebound.

Advantage:

• High build enables faster coverage with minimised slump.
• Can be applied upto 300mm in one application to vertical surfaces and upto 200mm overhead dependant on weight/ volume of aggregate
• Non caustic leads to safer handling / operating conditions
• Low rebound - controlled set allows new material to be embedded in applied mortar
• Chloride free liquid
• 28 days strength not adversely affected

Fosroc Conplast P211 Plasticizing Admixture is a chloride free water reducing admixture based on selected sugar-reduced  ligno sulphonates. It is supplied as a brown  solution which instantly disperses in water. It disperses the fine particles in the concrete mix, enabling the water content of the concrete to perform more effectively and improving the consistency of the concrete. This produces higher levels of workability for the same water content, allowing benefits such as water reduction and increased  strengths to be taken.

Uses:

• To improve the effectiveness of the water content of a concrete mix.
• At higher dosages to provide a cost effective means of reducing concrete permeability and thereby reducing water penetration.

Advantages:

• Allows specified strength grades to be met at reduced cement content or increased workability.
• Water reduction significantly improves compressive strengths at all ages and enhances durability through the production of low permeability concrete.
• Minimises the risk of segregation and bleeding and assists in the production of a dense, close textured surface, improving durability.
• Chloride free, safe for use in prestressed and reinforced concrete
