Concrete Admixture Manufacturer & Supplier in Bangladesh
Ducon is a trusted concrete admixture manufacturer and supplier in Bangladesh, producing water-reducing admixtures, superplasticisers, and waterproofing admixtures for concrete engineered for local weather, local cement, and local job-site conditions.
What is Concrete Admixture?
Concrete admixture is a chemical additive mixed into concrete or mortar, alongside cement, water, and aggregate, to change how the mix behaves, either while it is still wet or after it hardens. Depending on the type used, an admixture can slow down or speed up setting time, reduce the amount of water needed for the same workability, or make hardened concrete more resistant to water penetration.
In Bangladesh, where concreting often happens in high heat, high humidity, or during monsoons, a well-chosen admixture protects a structure long before cracks or leakage ever become visible. That is the core reason concrete admixture in Bangladesh has become a standard part of RMC batching, precast production, and cast-in-place structural work rather than an optional add-on.
Applications for Ducon Admixtures
Ready-mix concrete (RMC)
High slump retention keeps concrete workable during long transport and pumping.
Mass concrete pours
Retarders control heat and setting for large rafts, reducing thermal cracking.
High-rise & structural columns
Superplasticisers allow high-strength, low-water concrete in dense reinforcement.
Basements, tanks & foundations
Waterproofing admixtures cut permeability under constant water pressure.
Roof slabs (chad dhalai)
The right admixture gives a stronger, denser, more leak-resistant roof.
Precast production
Early-strength admixtures speed up demoulding and turnover.
Repair work
Quick-setting admixtures get repairs back in service faster.
Long-distance pumping
Flow-retaining PCE admixtures keep concrete pumpable far from the plant.

Frequently Asked Questions
What is the best concrete admixture for hot weather in Bangladesh?
A retarding admixture or a retarding PCE superplasticiser is usually best, because it delays setting and keeps concrete workable during Bangladesh’s high temperatures. Ducon’s Duconmix RSP 600 and PCE retarding range are formulated for this.
What is the difference between PCE and SNF superplasticisers?
PCE (polycarboxylate ether) admixtures give higher water reduction, longer slump retention, and better flow at a lower dosage than older SNF (sulphonated naphthalene) types. SNF is cheaper per litre but usually needs a higher dose and loses workability faster. For most modern RMC and precast work, PCE is the better long-term value.
How much admixture should I use per bag of cement?
Typically 0.5% to 2.0% of the cement weight, which is roughly 250 to 1,000 grams per 50 kg bag. The exact dose depends on your mix and conditions, contact our team for a trial dosage.
Can I get a waterproof basement using only an admixture?
A waterproofing admixture such as Duconmix WPR 700 greatly reduces concrete permeability and is a strong first line of defence. For basements under constant water pressure, we recommend combining it with a suitable Ducon waterproofing coating for full protection.
Do you offer bulk and wholesale pricing, and what is the minimum order quantity (MOQ)?
Yes. Ducon offers competitive bulk and wholesale pricing for contractors, ready-mix concrete plants, distributors, dealers, and large construction projects. The minimum order quantity (MOQ) varies depending on the specific concrete admixture and packaging size. Contact our sales team with your required product, quantity, and project details to receive a customized quotation and the applicable MOQ.
Which is the best waterproofing admixture for concrete in Bangladesh?
The best waterproofing admixture is one that reduces water permeability while improving concrete strength and durability. Ducon Waterproofing Admixture (Duconmix WPR 700) is designed to create dense, water-resistant concrete by reducing capillary pores and improving workability.
How do I become a Ducon dealer or distributor?
Submit your district and company details through our dealer form or WhatsApp. Our team usually responds within 2 business days.
Do your admixtures work with local cement brands?
Yes. We specifically test our admixtures against cement brands commonly available in Bangladesh, which is a core reason they perform reliably on local job sites.
