Concrete is, after water, the second most widely used material on the planet. The manufacturing of concrete generates about 4.5 percent of the world's human-induced carbon dioxide emissions. Replacing even a small portion of concrete with irradiated plastic could thus help reduce the cement industry's global carbon footprint.

Following this, we can filter the seawater through a funnel using a simple coffee filter into the beaker. This should enable the salt water to pass through the filter and end up in the beaker, leaving the sea sand behind on the coffee filter. This sea sand could then be used as a fine aggregate for concrete construction.

Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world's use of aggregates for concrete can be estimated at 25.9 billion to 29.6 billion tonnes a year for 2012 alone.
