MC-Bauchemie MC-TechniFlow 05
A mid-range PCE superplasticizer that trades a slight, controlled retardation for real slump retention and good early strength — built for RMC, precast and batching-plant concrete that has to survive haul time.
What is it?
A liquid, mid-range PCE (polycarboxylate ether) superplasticizer that combines strong water reduction with a controlled retarding action, so concrete stays workable longer without giving up early strength.
Where is it used?
Ready-mix and batching-plant concrete, precast units, low-grade self-compacting concrete, and composite-cement mixes where slump has to survive haul time and hot-weather placement.
Why use it?
It cuts water content while keeping the mix flowing and cohesive, holds slump through transit and pour, and still lets the concrete pick up early strength instead of dragging out the schedule.
How is it applied?
Dosed at up to 2% by weight of cement into the mixing water at the batching plant — added after the gauging water for best effect, with the exact rate fixed by trial mixes for the actual cement and site conditions.
About MC-Bauchemie MC-TechniFlow 05
Most PCE superplasticizers on an Indian batching-plant shelf sit at one of two extremes: cheap, fast-acting products that lose slump the moment the truck leaves the plant, or high-range grades tuned purely for chasing strength grade. MC-TechniFlow 05 sits in between. Built on mid-range polycarboxylate ether combination technology, its job is to give a producer a workable window that lasts — good water saving, excellent fluidity and relatively fast mixing at the plant, followed by good slump retention on the road and at the pour. Where many plasticising admixtures buy that slump life at the cost of a badly delayed set, MC-TechniFlow 05 is formulated to keep early strength development close to normal, with only a slight retarding side effect that shows up mainly at higher dosage or in hot weather.
That balance suits Delhi NCR’s mixed RMC-and-precast operators well. A single plant might send trucks 40 minutes across the city to one site while running a batching-plant order for kerbstones or blocks on the same shift — variable haul time, variable temperature, and a customer expecting consistent finish and stripping strength either way. Low cohesiveness and compatibility with air-entraining and foaming agents give the mix design room to move across composite-cement blends (PPC, fly ash, GGBS) without the admixture becoming the limiting factor. It’s also formulated free of corrosion-promoting components, which matters on RCC work where the specifying engineer is checking every material on the pour card for chloride content, not just cement and water.
The technical insight
The “mid-range PCE” tag on the datasheet is the operative detail. Polycarboxylate ether superplasticizers work by steric hindrance — the polymer’s side chains physically hold cement particles apart, which is why they achieve far higher water reduction than older sulphonated-naphthalene (SNF) products at a fraction of the dosage. Where PCE grades differ from each other is in side-chain length and grafting density, which tunes water reduction against slump-retention time and sets the retardation profile. MC-TechniFlow 05 sits mid-ladder in MC-Bauchemie’s own PCE range — below the higher water-reduction FK-series grades built for very high-strength or self-compacting mixes, above simple slump-retaining plasticisers with no real retardation control. Practically, it behaves predictably across normal M20–M40 RMC and precast work, without the tighter trial-mix discipline a high-range FK-grade demands at low water-cement ratios.
Where it is used
- Ready-mix concrete across variable haul distances, where slump has to survive transit
- Batching-plant operations running mixed RMC-plus-precast order books
- Pre-cast concrete — blocks, kerbstones, boundary and drainage elements
- Low-grade self-compacting concrete mixes
- Composite and blended-cement concrete (PPC, PSC, fly ash or GGBS)
- High-workability, pump-placed concrete for columns, slabs and walls
- Concrete where a smooth, high-quality exposed finish is specified
- Hot-weather concreting where ordinary plasticisers lose slump too fast
Key advantages
- Genuine water reduction with excellent fluidity at a moderate dosage
- Relatively fast mixing, so batching cycle times aren’t stretched
- Low cohesiveness keeps the mix workable, not sticky or hard to finish
- Good slump retention cuts down on re-dosing corrections at site
- Slight, controlled retardation paired with good early strength, not a blanket set delay
- Chloride content below 0.1% by weight, free of corrosion-promoting components
- Compatible with air-entraining and foaming agents, widening mix-design options
- Stable performance reported at elevated ambient temperatures
Limitations & considerations
- Retardation is “slight” on paper, but higher dosage or cold weather can stretch it further — always trial first
- The “up to 2%” dosage band is broad; the working rate must be fixed by trial batching, not assumed
- Positioned for low-grade self-compacting concrete only — high-grade SCC needs a dedicated SCC admixture instead
- Overdosing risks bleeding, segregation and extended setting time, as with any superplasticizer
- Shelf life is capped at 12 months; unopened packs still need protection from rain, sun, heat and frost
- The manufacturer’s datasheet does not print a specific IS/ASTM/BS clause number — request current compliance paperwork for project submittals
Selection & best practice
Run a preliminary trial mix with the actual site cement, aggregate and water before fixing a dosage — MC-Bauchemie’s own literature is explicit that dosages will vary from the “up to 2%” guidance based on real site conditions, temperature and equipment. Add it after the gauging water for the strongest effect, and mix long enough for the plasticising action to unfold fully — this is a mid-range PCE, not an instant-acting product. If a supplementary dose is needed at site, follow the manufacturer’s site-dosing rules rather than eyeballing it, and pair it with proper curing — Space Arc typically recommends an Emcoril-range curing compound alongside it, so the water saved at batching isn’t lost to evaporation after placement.

Industry use cases
Ready-mix concrete
An RMC plant in Gurugram serving sites 20–45 minutes away needs slump to survive the drive without a second dose at the gate.
Precast
A precast yard producing kerbstones and paver blocks wants one admixture that also works for its occasional RMC orders, instead of stocking two products.
Infrastructure / composite cement
A contractor pouring PPC-based composite-cement concrete for an infrastructure project needs a plasticiser proven compatible with fly-ash and GGBS blends.
Hot-weather concreting
A May–June pour in Delhi NCR is losing workability fast on ordinary plasticisers; the site engineer wants a product with documented stability at elevated temperature.
Batching plant standardisation
A batching plant standardising its admixture inventory wants one mid-range PCE that covers RMC, precast and composite-cement work without switching products.

How we position MC-Bauchemie MC-TechniFlow 05
Inside MC-Bauchemie’s own range, MC-TechniFlow 05 is the mid-range, slump-retaining option in the TechniFlow family — sitting alongside TechniFlow 06 and the higher water-reduction FK-series grades (FK02, FK30, FK32, FK35, FK61, FK62) that Space Arc also stocks for high-strength and self-compacting work; which one fits a given mix is a trial-mix and target-grade question, not a like-for-like swap. Outside the MC-Bauchemie range, Fosroc’s Auracast 100 is a genuine PCE alternative worth naming — a low-viscosity superplasticiser built specifically for precast yards chasing early demoulding strength. Specifiers running a pure precast line sometimes prefer that tighter focus; MC-TechniFlow 05 stays the better fit where one admixture also has to serve RMC and batching-plant orders with slump retention as the priority. As an authorised MC-Bauchemie distributor and applicator across Delhi NCR and Pan-India, Space Arc supplies it with dosing guidance and trial-mix support for the specific cement and aggregates on a project.
Fosroc Auracast 100 — Specifiers running a dedicated precast line rather than a mixed RMC-plus-precast operation sometimes prefer Fosroc’s Auracast 100, a low-viscosity PCE built specifically around early demoulding strength, over MC-TechniFlow 05’s broader retarding, slump-retention profile.
