Specialist Concrete Admixtures for Readymix and Precast.
Did you know – Adding a colloidal silica admixture at the point of batching can improve workability, reduce shrinkage cracking, and protect your concrete from the inside out.
Why Does Concrete Benefit from Specialist Concrete Admixtures?
Concrete producers and contractors face real mix challenges on every project:
- Readymix plants need consistent workability across varied conditions and delivery distances
- Precast manufacturers require reliable early strength, reduced shrinkage, and quality surface finish
- Congested reinforcing or complex formwork makes poor workability a costly problem
- Long-term durability and waterproofing are increasingly specified but hard to achieve with standard mixes
- Health, safety, and environmental standards demand nil-VOC, water-based solutions
Leaving these challenges unaddressed increases the risk of early deterioration, costly remediation, and asset underperformance.
MARKHAM’s colloidal silica admixtures address all of these challenges with a single, low-dose addition at the point of batching.

Why Choose MARKHAM specialist concrete admixtures?
- Integral protection from day one, permanently built into the concrete matrix
- Improved workability and rheology, making concrete easier to place and finish
- Reduced shrinkage cracking from the point of pour
- Long-term waterproofing and durability without additional treatments
- Water-based, nil-VOC, nil-odour and non-toxic, safe for operators and the environment
- Low-volume dosing, keeping logistics, storage, and handling straightforward
- Compatible with subsequent finishes, coatings and line-marking
- No foreign materials introduced; the admixture reacts within the concrete to produce new C-S-H
Our Specialist Concrete Admixture Range Is:
Designed to suit:
- Readymix batching plants supplying varied project types
- Precast manufacturing facilities and tilt-up construction
- Shotcrete and sprayed concrete applications
- Slag, fly ash, and high-SCM concrete mixes
- Projects specifying sustainable, low-VOC materials
- Potable water and food-grade concrete structures
Created to help:
- Readymix producers looking to improve mix consistency, workability, and reduce returns
- Precast manufacturers seeking faster demould times and reduced surface defects
- Structural engineers specifying integral waterproofing and long-term durability
- Contractors working with congested reinforcing, complex formwork, or difficult pour conditions
- Asset owners and developers seeking verified, documented concrete performance
MARKHAM ADMIXTURES ON A MAJOR HIGHWAY PROJECT.
This significant multi-bridge highway project presented real challenges with difficult weather conditions, unstable soils, and demanding structural requirements. MARKHAM provided admixtures for workability and durability, working directly with the readymix team to ensure consistent mix performance across every pour.

These projects demonstrated the benefits of our specialist admixture range.
PROLOGIS DIRFT3 MULTI-STOREY CAR PARK
Northampton
ANCOATS MOBILITY HUB
Manchester
Full waterproofing applied to the top deck and Level 1 using AQURON 300 and AQURON 2000, with CONQOR 47B sealing all penetrations. AQURON 1000 provided surface densification and durability enhancement across Levels 2–7, with no interruption to the construction programme.
ACCOLADE WINES WIND TURBINE
Avonmouth
GUILDFORD RAIL STATION CAR PARK
Guildford
AQURON systems protected all eight suspended decks, delivering durable waterproofing without future maintenance
ARLE COURT TRANSPORT HUB
Cheltenham
RUSH WALL WIND TURBINE BASE
Newport, Wales
AQURON admixture technology was specified for the concrete raft and turbine base to reduce drying shrinkage and control heat of hydration. This enabled large volume pours to be completed without surface cracking while achieving early strength gain ahead of programme.
