Is concrete bad for the environment?

To make cement, limestone (calcium carbonate – CaCO3) is heated to temperatures approaching 10000C, along with other feedstock materials such as clay (which contains silicates). At this temperature, the limestone (and other feedstock) breaks down into Calcium Oxide (known as Lime – CaO), Silicon Oxides and Carbon dioxide.

Heat resistant concrete

At higher temperatures (above about 800 degrees F), high-heat-resistant concrete is generally needed. Light-weight aggregates have proven to be more heat resistant and so that is the first step--use lightweight. When temperatures get extremely high, (above 1000 degrees F), calcium aluminate cement produces a fire-resistant concrete.
