RheoCem-Retain 2316 is a high-range water-reducing and retarding concrete admixture based on polycarboxylate ether (PCE) technology. It is designed specifically for ready-mix concrete that needs to stay workable for a longer period — particularly during long-distance transport and hot weather conditions.
RheoCem-Retain 2316 keeps concrete workable for 90 to 180 minutes depending on the mix design, temperature, and dosage. This makes it the most suitable product for RMC plants supplying concrete to sites that are 30 to 90 minutes away from the batching plant.
Compatible with fly ash, GGBS, silica fume, and all types of Portland cement. Conforms to IS 9103 and ASTM C-494 Type G.

Extends concrete workability for 90 to 180 minutes — no water addition needed at site
High water reduction — improves concrete strength and durability
Performs well in hot weather and tropical climatic conditions
Reduces pumping pressure — easier placement in congested reinforcement zones
Minimises shrinkage and improves long-term structural performance
Chloride-free — safe for reinforced and pre-stressed concrete
Compatible with fly ash and GGBS blended mixes
Conduct trial mixes at the batching plant before commercial production to establish the correct dosage
Measure the required quantity accurately using a calibrated dispenser
Add RheoCem-Retain 2316 to the gauging water or simultaneously with mixing water at the batching plant
Do not add directly to dry cement or dry mix under any circumstances
Mix for a minimum of 60 seconds after admixture addition for uniform distribution
Dosage range: 0.6% to 1.2% by weight of cementitious material — exact dosage to be confirmed by site trial
For hot weather concreting, dosage may be increased slightly — confirm by trial
Ready-mix concrete requiring extended workability — M30 to M50 grade
Long-distance concrete transport — 60 to 120 minutes transit time
Hot weather concreting where rapid slump loss is a concern
High-strength structural concrete for bridges, flyovers, and infrastructure
Concrete with high fly ash, GGBS, or silica fume content
Pumped concrete for high-rise buildings and congested reinforcement
Compatible with OPC 43, OPC 53, PPC, PSC, and blended cements
Do not combine with naphthalene or melamine based admixtures
Store in original sealed containers in a cool, dry, and shaded area
Protect from direct sunlight and temperatures above 45°C
Do not allow to freeze — store above 5°C at all times
If frozen, thaw slowly at room temperature and stir thoroughly before use
Shelf life is 12 months from date of manufacture under correct storage conditions
Non-toxic and non-flammable under normal handling conditions
Avoid prolonged skin contact and eye exposure
Wash skin thoroughly with clean water after handling
Rinse eyes immediately with clean water if contact occurs — seek medical advice if irritation continues
Use gloves and safety glasses when dispensing or handling large quantities

RheoCem-Ultra 2411 is a high-performance polycarboxylate ether (PCE) based superplasticizer developed for high-strength and high-grade concrete applications. It delivers high water reduction and excellent workability retention, making it suitable for M50 and above concrete grades, self-compacting concrete, and large infrastructure projects.
RheoCem-Ultra 2411 works at very low water-to-binder ratios — conditions where standard admixtures lose effectiveness. It ensures excellent flowability and compaction even in congested reinforcement zones without requiring additional vibration in most cases.
Compatible with silica fume, GGBS, fly ash, and all Portland cement types. Conforms to IS 9103 and ASTM C-494 Type G and F.
RheoCem-Flow 2304 is a polycarboxylate ether (PCE) based concrete superplasticizer designed for standard ready-mix concrete production. It improves the workability and flowability of concrete without increasing water content, making it suitable for M25 to M35 grade concrete used in everyday residential and commercial construction.
RheoCem-Flow 2304 works by coating cement particles and dispersing them evenly through the mix. This allows the concrete to flow freely and pump easily without adding extra water — which would otherwise reduce strength and durability.
Compatible with all types of Portland cement including OPC 43, OPC 53, PPC, and blended cements with fly ash or GGBS. Conforms to IS 9103 and ASTM C-494 Type G.
CureCem-Wax 2402 is a wax-based, white-pigmented concrete curing compound. When applied to freshly
placed concrete, it forms a continuous white film that seals the surface and prevents moisture from
evaporating during the critical curing period.
The white pigment reflects sunlight, helping to keep the concrete surface cooler — especially useful in hot
and sunny conditions. The white film also acts as a visual guide, showing workers which areas have
already been treated.
CureCem-Wax 2402 replaces traditional curing methods like water ponding and wet gunny bags, saving
water, labour, and time. Conforms to IS 9862 and ASTM C-309.
