Boral Concrete | Boral

What is Concrete? Concrete is composed of aggregates (crushed rock and sand) bonded together with ‘cementitious’ binders (cement) and water, which then hardens over time once laid in place. Generally coarse gravel or crushed rocks from Boral Quarries, along with finer materials such as sand, provide the required aggregate component. Cement is sourced from Boral’s Cement business.
