Dr. Fixit Pidicrete

Matching up with the requirements of our clients, we are involved in offering Dr. Fixit Pidicrete URP.

Dr. Fixit Pidicrete URP is based on modified styrene butadiene latex supplied as a ready to use bonding agent in liquidconsistency. It is used for repair of spalled concrete – floors, columns, beams, chhajas, slabs & waterproofing of toilets &bathrooms, small terraces etc. as it bonds strongly to old & new concrete and to plasters. It reduces shrinkage, preventscracking, dust pick up & improves abrasion resistance.

We are one of the most well-distinguished companies in the market that are into offering Dr.Fixit Pidicrete WP.

Dr. Fixit Pidicrete WP is a heavy duty, high solid content (47%) acrylic co-polymer liquid. It forms a matrix when mixed with cement & hence it provides excellent waterproofing properties. It can also be used as a bonding agent for new to old cementitious substrates and as an additive for repair mortars.

Dr. Fixit Micro Concrete is a ready to use dry powder which requires only addition of clean water at site to produce a free flowing non shrink repair micro concrete. It is composed of good quality cement, properly selected aggregates & additives. It is used & designed for repairing of damaged reinforced concrete elements like columns, beams & structure where the areas are restricted or not easily accessible for proper placement of concrete using vibrator. Dr. Fixit Micro Concrete has excellent flowability, workability & proper particle size to reach small & congested reinforcement.

Specification:

• Dr. Fixit Micro Concrete meets the requirement of ASTM C 109: 99, ASTM C 307, BS 1881 Part 207.

Areas of Application:

• Repair of damaged reinforced concrete elements like beams, columns, wall, etc. where access is restricted and compaction is not possible. 
• For Jacketing of RCC columns to increase load-taking capacity (strengthening of a vertical members)

Features & Benefits:

• Pumpable - Can be pumped or poured into restricted locations. 
• Flowable - Flowable mortar hence does not require compaction. 
• Shrinkage compensation – Controlled expansion system which compensates for shrinkage and settlement in the plastic state. 
• Strength - Develops high initial and ultimate compressive strength. 
• Moisture resistant - Offers excellent resistance to moisture ingress. 
• Durablity - Makes repaired sections highly durable & compatible to parent concrete. 
• Thickness build up - Can be applied at 100 mm thickness at one stroke 
• Chloride content - Contains no chloride based additive so prevents corrosion of reinforcement. 
• Early reinstatement -Rapid strength gain helps in early reinstatement & removal of shuttering.

Method of Application:
Surface Preparation

• Clean the surface and remove loose concrete, dust, oil, paint, grease, waterproof coating, etc. 
• Expose fully any corroded steel in the repair area and remove all scale and corrosion deposits. Light shot blasting is highly recommended. Apply Dr. Fixit Rust Remover for rust free bars. 
• For Cathodic Protection, apply Dr. Fixit Epoxy Zinc Primer over the cleaned re-bars and allow it to dry before pouring of Dr.Fixit Micro Concrete. 
• Saturate the substrate with water to prevent absorption of water from the mixed material. 
• In case of a very old concrete substrate, it should be primed by applying one coat of Dr. Fixit Epoxy Bonding Agent. Allow the bonding agent to reach tacky condition before pouring of mix concrete.

Mixing:

• Use PAN Mixer for mixing of Dr. Fixit Micro Concrete. 
• Charge 85-90 % of clean & potable mixing water (3.75 to 4 liters per 25 kg bag) to a PAN Mixer. 
• Start addition of Micro Concrete powder slowly under continuous mixing. Keep mixing for 2 minutes. Add balance quantity 15 – 20% of mixing water & again mix for another 2-3 minutes to form a homogeneous, free flowing, uniform & lump-free mix.

Application:

• Pour or pump the mixed Dr. Fixit Micro Concrete into a watertight shuttering. 
• Cure the repaired concrete for minimum 7 days before removing the shuttering or alternatively use Dr. Fixit Curing Compound for curing. 

Precautions & Limitations:

• Dr. Fixit Micro Concrete can applied in section upto 100 mm depth. 
• For thickness more than 100 mm, addition of pre-calculated aggregates may be required. Consult technical team for more details. 
• Strictly follow water-powder ratio as specified. 

Dr. Fixit Pidicrete MPB is composed of acrylic co-polymer emulsions & additives. It is used as bonding agent for new to old substrates & cement mortar modifier because it provides strong bonds to old & new concrete. Improves tensile & flexural strength of concrete and increases the durability of the structure. When mixed with cement, It forms a matrix & provide excellent waterproof coating.

Areas of Application:

• Concrete repair – spalled concrete, floor, columns, beams, chajja, slab & parapet etc. 
• Bond coat – Old to new concrete, masonry, stonework plaster, fixing or re-fixing slip bricks, tiles, marbles & bedding. 
• Priming – Reinforcement steel. 
• Additive – Additives for renders & mortars. 
• Coating – As an flexibiliser to cement

Features & Benefits:

• Chloride content - Contains no chloride all. 
• User friendly - Single component ready to use, simply brushed onto concrete as a primer. 
• Bonding - Provides excellent bond to concrete, masonry, Stonework, plywood, gypsum & plaster. 
• Strength - Improves tensile, flexural and compressive strength as compared to control concrete hence increases the durability of structures. 
• Compatibility - Compatible with all common cements hence it is versatile. 
• Dust generation - Excellent as a dust proof sealer 
• Waterproofing - Improves waterproofing properties & cement & cementitious compositions. 
• Flexibility - Improve flexural strength of cement & cementitious composition.

Method of Application
Surface Preparation 

• Clean the surface and remove any dust, unsound or contaminated material, loose plaster, oil, paint, grease, corrosion deposits or algae. Where breaking out is not required, roughen the surface and remove any laitance by light scabling or grit blasting. 
• Expose fully the corroded steel in the repair area and remove all loose scale and corrosion deposits. Steel should be cleaned to bright condition particularly the hidden portions of the exposed steel bars.

Application
Reinforcing steel priming

• Apply one coat of Dr. Fixit Pidicrete MPB mixed cement slurry (1:1 by volume) to all exposed steel reinforcement and allow it to dry. A second coat application is also recommended. Allow it to dry. The surface should be thoroughly soaked with clean water prior to application of Dr. Fixit Pidicrete MPB. 
• Apply Dr. Fixit Pidicrete MPB with brush or rollers on the substrate and avoid ponding and remove any excess material. The repair or topping application should be carried out whilst the primer is still tacky.

Render and Mortars:

• A suitable mix ratio for patching repair mortar or render. Mix design - Portland Cement : 50 kg,
• Washed sand : 150 kg & Dr. Fixit Pidicrete MPB : 20 litres. Sufficient water can be added to give the required consistency

Bonding Slurry Coat:

• Mix Dr. Fixit Pidicrete MPB with cement where extra adhesion is required.
• Recommended mix shall be 10 litres of Dr. Fixit Pidicrete MPB mixed with cement in the ratio 1:1 by volume.

Waterproofing With cement as an additive for achieving waterproofing Curing:

• Cure the repaired area by using Dr. Fixit Pidicrete MPB to prevent rapid loss of water. In severe drying conditions additional curing methods may also be necessary.
• Protect uncured mortar from frost and rain.

Coverage:

• As coating: Approximately 5-7 m2/litre

Shelf Life & Storage:

• Best before one year from the date manufacture when in sealed pack and stored under proper condition.
