Independent Technical Advice. Practical Solutions. Better Concrete.
Concrete Engineering That Improves Performance, Consistency & Cost
Concrete & Geotechnical Engineering (CGE) provides independent technical support to concrete producers, quarry operators, contractors and construction materials businesses across Australia.
We help clients improve mix performance, reduce variability, optimise material use, solve production problems and strengthen technical control.
Better concrete starts with understanding the whole system — materials, mix design, batching, testing and production.
Trusted by Concrete & Quarry Businesses
“We saw immediate improvement on site. Glenn and the CGE team were responsive, technically sharp, and genuinely understood the practical side of volumetric operations, not just the theory.”
— HOX Concrete
“CGE have become a very valuable part of our concrete and quarry operation. Their technical support is second to none, and the level of service and knowledge is hard to find.”

Practical Experience Behind the Advice
CGE is led by Glenn and Matthew Carson, bringing extensive practical experience across concrete production, quarry materials, mix design, technical management, quality systems and construction materials.
Glenn has spent more than three decades working throughout the concrete and construction materials industry, including senior national technical and product management roles.
His experience spans:
-
Concrete mix design and optimisation
-
Ready-mixed concrete production
-
Quarry and aggregate materials
-
Technical and quality management
-
Strength and variability analysis
-
Batching and production systems
-
Specialist concrete development
-
Major infrastructure and project-specific concrete
-
Admixtures and cementitious systems
-
Troubleshooting real production problems
Matthew adds broader engineering and technical capability across concrete, geotechnical and construction materials.
Together, CGE provides clients with advice grounded in real operational experience — not just theory.
Our focus is on solutions that work in the plant, in production and on site.
Data First. Decisions Second.
Good technical decisions start with good information.
When CGE reviews a concrete operation, we consider the full picture.
We look at:
MATERIALS
Cement, SCMs, sand, aggregates, gradings, moisture and admixtures.
MIX DESIGNS
Cementitious content, water-cement ratio, aggregate proportions, workability and strength targets.
BATCHING
Actual batch weights, water additions, moisture corrections, admixture dosage and production variation.
TEST RESULTS
Strength performance, average strength, standard deviation and trends over time.
YIELD & PRODUCTION
Yield performance, batching accuracy and operational consistency.
COMPLIANCE
AS 1379 requirements, project specifications and quality systems.
The objective is not simply to identify that something is wrong.
It is to understand why it is happening and determine the most practical way to improve it.

Why we're different
Are Your Mixes Working Harder Than They Need To?
High average strength can look like good performance.
But if your mixes are consistently producing well above their required strength, you may be carrying unnecessary cementitious cost.
The answer is not simply to remove cement.
Before optimisation, you need to understand:
-
Standard deviation
-
Batch variability
-
Moisture control
-
Aggregate grading
-
Water demand
-
Admixture performance
-
Yield
-
Production capability
Once those areas are understood and controlled, mix optimisation becomes a much safer and more effective process.
Cement isn’t always the first answer.
Sometimes the Problem Starts Before the Concrete Plant
Changes in sand grading, aggregate shape, fines, moisture or quarry production can significantly affect concrete water demand, workability and strength.
Because CGE works across both concrete and quarry materials, we can investigate the relationship between raw materials and final concrete performance.
That means looking beyond the batch plant when the data tells us the problem may be somewhere else.
Better materials control leads to better concrete control.
Independent Advice Means No Product Agenda
CGE is independent.
We are not tied to a cement manufacturer, admixture supplier, aggregate producer or testing laboratory.
Our recommendations are based on:
-
Your materials.
-
Your production data.
-
Your concrete.
-
Your business.
Sometimes the right recommendation is to change the mix.
Sometimes it is to improve batching.
Sometimes it is to investigate the quarry.
And sometimes the best recommendation is to change nothing.
Our role is to provide the advice we believe will deliver the best technical and commercial outcome for your operation.
Technical Support Without the Full-Time Overhead
Not every concrete producer needs a full-time Technical Manager.
But every producer needs access to experienced technical support when complex issues arise.
CGE’s Virtual Technical Manager service can provide ongoing support with:
-
Mix performance
-
Strength and standard deviation
-
Materials
-
Batch data
-
Yield
-
Moisture
-
Compliance
-
Troubleshooting
-
New product development
-
Specialist mixes
-
R&D
-
Technical decision-making
The service can be structured around the needs of your business — from occasional support through to regular monthly technical oversight.
Developing What Comes Next
The concrete industry is changing.
Lower-carbon cementitious systems, GL cement, slag, calcined clay, manufactured sand, recycled materials and new technologies are creating opportunities for producers willing to innovate.
CGE can help turn an idea into a structured technical development program.
From the initial question:
“Can we make this better?”
through to trials, testing, analysis and commercial production.
Good R&D should solve a real business problem and create a practical outcome.
Real-World Technical Support
Our clients engage CGE because they want more than a report.
They want someone who will work with their team, understand their production environment and help them solve the problem.
That might mean reviewing batch data remotely.
It might mean redesigning a mix.
It might mean working through aggregate grading with the quarry.
It might mean supporting a production trial.
Or it might simply mean having someone experienced to call when something does not look right.
“A standout for us is Glenn and Matthew’s support. I can call them any time with a technical issue and they’ll answer and help us work through it.”
