Want to understand what makes SteelX 8:45 different?

The secret is in the twist. 🔩

SteelX 8:45 is a Twisted Steel Reinforcement (TSR) product designed to mechanically engage with the surrounding concrete.

As it is pulled through the concrete, it has to untwist through the matrix rather than simply slide out.

That torsional anchorage is what creates such a strong interaction with the concrete and helps SteelX deliver a stable response after cracking.

In simple terms, it’s not just sitting in the concrete, it’s actively working with it.

🎥 This pullout test gives a great visual of how that mechanism works in practice.

If you want to learn more about where SteelX 8:45 can add value in your next concrete design, talk to us.

E5 Internal Cure and E5 Liquid Fly Ash were incorporated into the shotcrete mix to help improve durability and reduce permeability.

For pool structures, keeping water where it belongs is critical.

E5 Internal Cure helps retain water inside the concrete so the cement can hydrate more effectively, while E5 Liquid Fly Ash helps create a denser concrete matrix with fewer pathways for water to move through.

The result is concrete designed to perform better from the inside out.

That makes the E5 combination well suited to applications such as:

-Swimming pools
-Water-retaining structures
-Shotcrete walls
-Below-ground concrete
-Projects where long-term durability matters

It’s a simple idea: improve the concrete itself, rather than relying only on surface-applied solutions later.

Make concrete better.

21/10/2026

Construction is hard enough without the concrete making it harder.

Every pour has a program to meet, a team to coordinate, a design to deliver and a result everyone needs to stand behind.

At McClay Industries, we’re focused on helping make that part of the job better, bringing practical thinking and better concrete solutions to the people designing, managing and building projects every day.

That’s what Make Concrete Better is all about.

Better. Faster. Stronger.

A carpark entrance works hard from day one.

Constant vehicle movement, turning loads, weather exposure and daily wear all place demand on the concrete.

For this project, E5 Internal Cure and SteelX 5:25 were incorporated into the mix to help improve durability and crack control.

The aim was simple: build better performance into the concrete from the start. No added complexity. Just a smarter approach to long-term performance.

Have a carpark, pavement or high-traffic slab coming up? Talk to McClay Industries about designing better concrete from day one.

There's a reason more engineers are picking MiCD over a stack of spreadsheets.

It's a free concrete design platform — run your CCAA T48 and AS3600 calcs in one place instead of cross-checking two or three tools every time you touch a load case. And if you want the extra edge, SteelX is built right in.

Curious what it looks like on your next job?

Myth: concrete reaches full strength at 28 days.
Reality: 28 days is when we stopped measuring, not when the concrete stopped getting stronger.

Hydration doesn't have a deadline. Cement keeps reacting with water for months, even years, as long as moisture is available. The 28-day figure exists because it's a practical standard for specification and testing, most of the useful strength gain has happened by then, so it's a good enough checkpoint. It was never a claim that strength gain stops.

What actually determines how much of that later strength you get to keep:
— How long the slab was kept moist (curing duration, not just curing existence) — Ambient temperature and humidity during the cure window. Whether curing stopped early because the slab "looked" dry.

A slab can look fully cured on the surface days before it's anywhere close to done hydrating underneath. Cutting curing short doesn't just slow strength gain — it caps it, because once the moisture needed for hydration is gone, that reaction doesn't restart.

What's your standard curing duration on-site, and does it change by season?

"Just add more steel" isn't a watertight design strategy. Understanding how the section behaves under service loads is.

Six things that actually decide whether a structure stays dry:

Crack width. Reinforcement stress. Fibre contribution. Section capacity. Shrinkage and restraint. Permeability of the matrix.

Most of these get locked in long before anyone asks about a waterproofing system.

Which of these six gets the least attention on a typical job — in your experience?

Good finishability starts with getting the surface right early.

A roller tamper helps level and consolidate the concrete as it is placed, making the next stages of finishing easier for the crew.

Simple, practical and effective on all slab pours.
