Supermixcrete
SUPERMIXCRETE
Supermixcrete has been designed using the latest advanced superplasticizers and unique concrete design techniques to create concrete with higher workability and higher compressive strength. Enhanced rheology of supermixcrete eases the effort of concrete pumping for hi-rise buildings and helps to optimize RCC design cost.
- Higher compressive strength
- Higher durability concrete
- Higher modulus of elasticity
- Helps to design thinner structures/sections with the same load-bearing capacity
- Helps to provide more floor space area
Application Areas
- Infrastructure projects – bridge girder, piers, pilons, deck slab, etc.
- Hi rise building structures – column, shear walls, flat slab, etc.
Technical Specifications
- Retention time up to 4 hrs
- Compressive strength (28 days): 50 Mpa to 70 Mpa
- Slump at site: 150 to 200 mm
Great Experience in building

Ready Mix Concrete (RMC) is factory-produced concrete made using precise, computer-controlled mix designs and delivered fresh to site in transit mixers. It ensures consistent strength, workability, and durability while reducing on-site labour and material waste.
RMC provides uniform quality, faster construction, and cleaner sites. It eliminates manual mixing errors and is ideal for space-constrained areas like central Kolkata and Howrah, helping projects progress up to 30% faster.
RMC prices in Kolkata generally range from ₹4,500 to ₹7,500 per cubic metre, depending on grade, quantity, and delivery distance. Firstchoice Readymix offers transparent, project-specific quotes with no hidden costs.
All concrete mixes undergo BIS-compliant laboratory testing for strength, workability, and durability. With 24+ RMC plants, Firstchoice Readymix maintains consistent quality across every batch and provides test reports for major pours.
High-rise construction typically requires high-strength concrete such as M50 grade and above. Firstchoice Readymix supplies specialised pumpable and flowable mixes designed for vertical construction and dense reinforcement.
Slump measures the workability and flow of fresh concrete. Controlled slump ensures easy pumping, proper placement, and consistent strength—especially important in Kolkata’s humid climate.
Yes. Ready mix concrete can be tailored for local weather conditions. Firstchoice Readymix adjusts mix designs and admixtures to ensure reliable performance during monsoons and high summer temperatures.
Absolutely. RMC is ideal for individual homes and renovations, offering cleaner sites, faster slab casting, and stronger foundations compared to hand-mixed concrete.
RMC is designed to be placed within a controlled time window after batching. Firstchoice Readymix delivers pour-ready concrete within standard freshness limits to maintain strength and workability.
With 10+ years of experience, 5,000+ projects, and 24+ strategically located plants across Kolkata and Howrah, Firstchoice Readymix ensures timely delivery, BIS-compliant quality, and expert technical support for every project.
