Read Chapter 12: — HEAT IN THE CONCRETE

The project moved from earthworks into structures, and the desert found new ways to interfere.

Concrete placed in extreme heat behaved badly if treated like concrete in ordinary weather. Aggregate arrived hot. Mixing water warmed in storage. Rapid evaporation threatened plastic shrinkage. Temperature differentials increased cracking risk.

Daniel’s team changed the process.

They shaded aggregate stockpiles, insulated water tanks, shifted major pours toward evening and night, used chilled water when necessary and reviewed admixture dosage with the materials laboratory.

On the first major box-culvert pour, Graham appeared at eleven at night carrying a torch and his battered enamel mug.

Daniel looked at it.

“You brought that from Britain?”

“Had it thirty years.”

“Does it have heritage listing?”

“Mock it and I’ll bury you under the culvert.”

They checked reinforcement, formwork and temperature records together.

At one point Graham crouched to inspect a joint, braced one hand on his hip and unconsciously stepped his right foot forward.

Daniel froze.

It was his own posture.

Not similar.

Exact.

Maya noticed Daniel watching.

Later she said, “You two do that all the time.”

“Do what?”

“Stand the same way. Frown the same way. You both tap a drawing twice when you’re about to disagree with someone.”

Daniel laughed. “Occupational disease.”

“Maybe.”

She looked as if she wanted to say more.

The concrete trial succeeded.

So did the next one.

By the time the first elevated structure rose from the sand, the site had developed methods that would be used across later sections.

The owners praised the technical team.

Graham accepted the compliment by immediately pointing out six things that still needed improvement.

Toby whispered, “If he ever says well done without adding a threat, I’ll assume he has been replaced by an impostor.”

Daniel smiled.

But the shared posture stayed in his mind.
