About SIKA REP MICRO CRETE-4
91 000 74051 SikaRep Microcrete-4 is a factory-blended, high-performance, non-shrink, cementitious micro-concrete mix. Designed for deep structural repairs in concrete, it flows easily into restricted forms, compensates for shrinkage, develops rapid strength, and bonds well with old concrete. Ideal for repairing damaged beams, slabs, columns, tunnels, basements, and large gapes.
Key Features & Benefits
Pourable / pumpable consistency; flows easily without the need for vibration.
Dual-stage expansion to compensate for plastic shrinkage and settlement.
Rapid strength gain: strong early (1-day, 3-day) strengths enabling quicker reinstatement.
High ultimate strength with good impact, vibration, chemical resistance; non-corrosive, non-toxic.
Contains no added chloride, so safer for reinforced concrete.
Adjustable consistency by controlling water: you can adjust flow / workability while maintaining properties.
Q1. What is the price per 30 kg bag?
Typical posted rates are around 000 per 30 kg bag, depending on Please visit CIVILIZEMART
Q2. How much area / volume will 1 bag cover?
Consumption is approximately 1,900 kg of powder per cubic meter of concrete (with water : powder = 0.15). So 30 kg covers 0.0158 m about 15-16 liters volume roughly. Exact depends on depth / thickness.
Q3. Can it be pumped?
Yes the product is designed to be pourable/pumpable into restricted formwork without vibration.
Q4. Is it safe for reinforced concrete / steel?
Yes it is non-corrosive, contains no added chloride.
Q5. What is shelf life & storage?
Shelf life is 6 months from date of production if stored in unopened bags, in dry conditions, at temperature between +5-35 C.
Q6. Can the mix be adjusted for more flow?
Yes by using water-powder ratio within the recommended range (0.14 to 0.16) for higher flow, but avoid adding more water than specified as that can degrade strengths & increase shrinkage.
High Strength for Lasting RepairsSIKA REP MICRO CRETE-4 offers exceptional compressive strength (>55 MPa at 28 days), making it suitable for demanding structural repairs and jacketing. Its robust chemical composition ensures long-term durability, even in challenging conditions. The high early strength and shrinkage-free characteristics guarantee safe and effective rehabilitation of concrete structures, adding value to infrastructure and peace of mind to engineers and contractors.
Versatile Application and Easy UsageDesigned as a pourable repair mortar, SIKA REP MICRO CRETE-4 is ideal for use in vertical and overhead areas through formwork casting. Its ready-to-mix, flowable powder simplifies the preparation process, saving time on-site. Suitable for filling voids and gaps in RCC structures, it's widely used in rehabilitation and strengthening projects, ensuring compatibility with various structural configurations.
Safe, Reliable Handling and StorageCertified as chloride-free and highly pure, SIKA REP MICRO CRETE-4 prioritizes safety and quality. The product is slightly alkaline (pH >12), so users should wear gloves and masks to avoid contact with skin and eyes. Supplied in 30 kg bags, it offers a 6-month shelf life when stored in dry conditions. Immediate availability ensures minimal project delays and consistent supply.
FAQ's of SIKA REP MICRO CRETE-4:
Q: What is the recommended process for mixing and applying SIKA REP MICRO CRETE-4?
A: Mix SIKA REP MICRO CRETE-4 powder with clean water at a ratio of 0.14-0.16 until a smooth, flowable consistency is achieved. Pour the mixture into prepared formwork for vertical or overhead repairs. Ensure surfaces are clean and pre-wetted before application to maximize adhesion.
Q: How long does SIKA REP MICRO CRETE-4 take to set and achieve full strength?
A: The initial setting time is typically 3-4 hours. Full compressive strength (>55 MPa) is reached within 28 days under standard curing conditions, making it suitable for fast-track repair projects.
Q: Where is SIKA REP MICRO CRETE-4 most effectively used?
A: SIKA REP MICRO CRETE-4 excels in structural repairs, jacketing, and rehabilitating RCC structures. It is commonly applied to fill gaps and voids, or to restore damaged vertical and overhead concrete elements by formwork casting.
Q: What are the main benefits of using SIKA REP MICRO CRETE-4 for repairs?
A: Key advantages include non-shrink performance, high early and final strength, excellent adhesion, flowable application, and chloride-free composition. These features ensure long-lasting and safe concrete repairs with minimal maintenance.
Q: How should SIKA REP MICRO CRETE-4 be stored and handled safely?
A: Store the unopened bags in a dry environment to maintain a 6-month shelf life. Always handle the product with gloves and a mask, as it is alkaline and may irritate skin or eyes upon contact.
Q: What coverage can I expect from SIKA REP MICRO CRETE-4?
A: The product delivers approximately 2.15 kg per m2 per mm of thickness. Coverage will vary depending on the total area and required repair thickness.
