1940s 

Infrastructure demands of the WW II era challenged the construction industry to develop building techniques that would promote durable, cost-effective and long-lasting structures.

War-driven projects included production plants, railway piers, bridges, tunnels, sewer systems and other elements of the national infrastructure.

In support of these efforts, Master Builders technology continued to evolve with advances in concrete curing and air-entraining admixtures that helped prevent cracking from seasonal freeze/thaw cycles.

As the Allies were winning the war overseas, Master Builders was working hard to create the concrete innovations that would lay the foundation for the post-war boom.

See how concrete curing and air-entraining admixtures are used today.
