A Simple Guide to Concrete Cube Testing

This corresponds to 1.5 t of concrete per capita annually. Concrete is an environmentally friendly material and the overall impact on the environment per ton of concrete is limited (1). The CO2 emission related to concrete production, i.e. primarily from cement production, is between 0.1 and 0.2 t per tonne of produced concrete.
