About us
Admixor is the concrete admixture manufacturing and export brand serving overseas markets. Backed by our own plant and laboratory, we supply ready-mix producers, precast and pile plants, contractors and overseas distributors with stable supply and technical support.
Our team is made up of engineers from polymer synthesis, concrete materials and construction technology backgrounds. Core members have more than ten years of experience in polycarboxylate superplasticizer synthesis and concrete admixture application.
On the production side we cover four process families: polyether macromonomer synthesis, polycarboxylate polymerization, naphthalene condensation and finished blending. Formulations are adjusted to the climate, cement characteristics and site practices of each target market — we do not sell one product into every country.
We serve ready-mix plants, precast and pile manufacturers, infrastructure contractors, and overseas distributors looking for long-term supply and local technical backup. We welcome factory audits, third-party testing and small trial orders.
How we got here
In-house PCE synthesis process developed and put into production
Dual naphthalene and polycarboxylate production lines commissioned
Export documentation and technical literature system established; entry into Southeast Asia and Africa
Full-range admixture packages plus cement-specific formulation service
Production & capacity
A complete process chain from polyether macromonomer synthesis to finished-product blending, with critical steps under centralized DCS control and fully traceable recipes.
Macromonomer synthesis
HPEG / TPEG / EPEG macromonomers produced in-house, controlling molecular weight distribution and double-bond retention — the foundation of final performance.
Polymerization
DCS controls dosing temperature, feed rate and reaction time; molecular weight and side-chain density follow the grade recipe for batch-to-batch consistency.
Blending & formulation
Mother liquor combined with functional components (slump retention, retardation, air entrainment, defoaming) and tuned to destination climate and cement.
Filling & packing
Liquids in IBC totes, 200 L drums or flexitanks; powders in 25 kg composite bags or jumbo bags, with OEM labelling available.
Quality & certification
Quality control is not a final inspection — it runs through raw materials, in-process control, finished goods and dispatch. The systems and standards below are what we work to.
Cement paste fluidity
Initial and time-dependent fluidity per GB/T 8077 to judge cement compatibility.
Concrete water reduction
Reference concrete comparison to measure actual water reduction and strength ratio.
Air content & setting time
Controls entrained air and setting deviation so the construction schedule is not disrupted.
Chloride & alkali content
Strict chloride limits to avoid rebar corrosion; low-alkali grades available for reactive aggregates.
Storage stability
Heat/cold cycling and long-term static storage tests to verify against separation and sedimentation.
Third-party verification
SGS / BV / Intertek testing can be arranged on request.
R&D and technical service
Admixture performance depends on the combination of cement, SCMs, aggregates and climate. Our technical service is built around one goal: making the product work on your materials.
Tailored molecular design
Backbone length, side-chain density and functional groups adjusted to the adsorption behaviour of a specific cement.
Cement compatibility database
Accumulated compatibility data across major cement brands in multiple markets, giving a reliable first dosage estimate in a new country.
Trial mix support
Laboratory mix reports and site trial batching plans including dosage–slump–strength curves.
Problem diagnosis
Root-cause analysis and corrective plans for bleeding, segregation, rapid slump loss, abnormal setting or low strength.
