RetarCem-Lite L25 is a surface-applied concrete retarder that delays the setting of the surface mortar layer while the concrete beneath sets normally. It is applied to the inside of formwork before concreting, or directly to the fresh concrete surface, to achieve a shallow exposed aggregate finish after stripping and washing.
RetarCem-Lite L25 is water-based, low odour, and easy to apply. The depth of aggregate exposure is controlled by the dosage applied.
Form
Liquid

Brown to amber liquid
Base
Organic retarder solution — water based
Retardation Depth
2 to 5 mm surface mortar layer
Coverage on Formwork
6 to 10 sq. metre per litre
Washing Time after stripping
6 to 12 hours
pH Value
Mildly acidic to neutral
Packaging
5 litre can / 20 litre can
Creates natural exposed aggregate finish with consistent shallow texture
Depth of exposure controlled by dosage — flexible aesthetic options
Only the surface layer is retarded — no effect on bulk concrete strength
Water-based — safe, low odour, and easy cleanup
Reduces need for mechanical grinding or sandblasting for textured finish
Consistent results across large surfaces when applied uniformly
Apply RetarCem-Lite L25 to the clean inside face of the formwork using a brush or roller before concreting
Ensure uniform coverage — no dry patches or runs
Allow the applied coat to dry before assembling formwork and pouring concrete
After stripping formwork — wait 6 to 12 hours
Wash the retarded surface thoroughly with a water jet to expose the aggregate
For direct surface application — apply immediately after finishing the fresh concrete surface
Do not wash too early — aggregate may be dislodged; do not wait too long — surface may harden
Decorative retaining walls with exposed aggregate finish
Architectural concrete columns and feature walls
Landscape concrete — garden walls, boundary walls, planters
Decorative precast panels and paving slabs
Swimming pool surrounds and water feature walls
Compatible with all standard concrete mixes and aggregate types

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.
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.
