Boral Cement | BoralCement is primarily used for concrete, the world's second most consumed material after water. Concrete's appliions are boundless, meaning the cement must be flexible to a range of tasks. Boral's cement can therefore found in buildings of all types, roads, bridges, tunnels, pathways, public spaces such as parks and plazas, walls and barriers and art installations.

What is coal used for?Coal is primarily used as fuel to generate electric power in the United States. In coalfired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into highpressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of all electricity in the United
Coal and the environment · Reuse and recycling can also reduce the environmental effects of coal production and use. Land that was previously used for coal mining can be reclaimed and used for airports, landfills, and golf courses. Waste products captured by scrubbers can be used to produce products such as cement and synthetic gypsum for wallboard.
Blended CementEasily the most widely used supplementary material, fly ash is a byproduct of coal combustion in electric power plants. The fly ash is filtered out of exhaust gases as a fine powder. Our Lehigh Cement Company brand for a fly ash blended cement is InterCem®, which we produce at our Edmonton, Canada cement plant today.
