Carbon Cycle

  • Earth 'breathes' every day of year
  • Summer Months: Plants photosynthesize, they absorb energy from the Sun and consume CO2 from the atmosphere to use as a source for growth
  • Winter Months: Plants save energy by decreasing photosynthesis. This process results in lower absorption CO2 by the ecosystem, returning the cycle to its starting point
  • Earth is no longer 'breathing' in a stable pattern, the 3 most common fossil fuels (Coal, Oil and Gas) release CO2 during combustion
  • Photosynthesis can no longer keep up with absorption of these increasing CO2 levels

Concrete:

Frames

  • Frames can be precast in a factory or formed onsite by pouring liquid concrete into temporary formwork.

  • Reinforced cement concrete contains steel bars, often referred to as re-bar.

  • This combination
    works well, as concrete is strong in compression and steel is strong in tension.
