Concrete Admixtures

A concrete mix that segregates on site, sets too fast in the afternoon heat, or fails a slump test at the pump is rarely a cement problem. More often, it is the wrong admixture, the wrong dosage, or no admixture at all in a mix design that needed one. Since admixtures are dosed in small quantities but change how the entire batch behaves, getting this one input right has an outsized effect on everything that follows, from workability at the pump to strength at 28 days.

CretePro Trading is an authorised distributor of MAPEI and MC-BAUCHEMIE construction chemicals in India, supplying concrete admixtures to ready-mix plants, contractors and precast units across the country.

Admixtures are chemical compounds added to concrete at the batching stage in small dosages, typically calculated as a percentage of cement weight, to change how the mix behaves without adding bulk the way cement, sand or aggregate do. Depending on the chemistry, an admixture can act on the fresh concrete, altering workability, setting time or air content, or on the hardened concrete, affecting strength, permeability and long-term durability.

The reaction is dependent on cement chemistry, water content and ambient temperature so the same admixture can behave differently from one batching plant to another and the dosage is therefore always confirmed against local materials, rather than being applied as a fixed number.

Superplasticisers for Low Water-Cement Ratios

Superplasticisers, also called high-range water reducers, allow a pumpable or self-compacting mix at a low water-cement ratio, which is standard practice for RMC plants and congested reinforcement.

Retarding Admixtures for Longer Working Time

Retarding admixtures slow the setting reaction, which matters for large continuous pours and for hot-weather concreting, a near year-round condition across most of India.

Accelerating Admixtures for Faster Strength Gain

Accelerating admixtures speeds up setting and early strength gain, useful for precast schedules, cold-region work and repair jobs that need fast turnaround.

Integral Waterproofing Admixtures for Reduced Permeability

Integral waterproofing admixtures reduce the permeability of the concrete itself by blocking capillary pores, typically used to reinforce a surface-applied waterproofing system in tanks and basements rather than replace it.

Corrosion Inhibitors for Reinforcement Protection

Corrosion inhibitors protect embedded reinforcement from chloride and carbonation attack, relevant for coastal structures and marine-exposed sites.

Air-Entraining Admixtures for Durability

Air-entraining admixtures introduce controlled microscopic air bubbles to improve workability and durability in specific climate and exposure conditions.

Admixture pricing depends on the chemistry selected, the dosage rate required for your mix design, and the total quantity ordered for the project, so RMC plants and contractors typically request a quote against a defined volume rather than a per-litre retail price.

Trial batching against local cement and aggregate is also recommended before committing to a full order, since this can affect the final dosage and cost. Share your mix design and project scope with our team for an accurate quote.

CretePro Trading supplies genuine MAPEI and MC-BAUCHEMIE concrete admixtures with manufacturer technical data sheets and safety data sheets, not repackaged or unverified stock. Both partner brands manufacture under ISO 9001, ISO 14001 and ISO 45001 certified quality, environmental and safety systems, giving consultants documentation for project audits and structural sign-off.

Our technical team reviews your mix design, cement type and site conditions to recommend the correct admixture and dosage, and we hold stock in India for delivery to RMC plants and contractors nationwide on batching-plant timelines.

If a pour is not behaving as expected, whether that is slow setting, poor workability or unexpected bleeding, our team is available to troubleshoot on-site.
