Comprehensive Approach to Calculate Oxygen …

For concrete, oxygen gas could not be a threatening of reinforcement corrosion because pH value of pore solutiuon is around 13.5. There is a lot more calcium hydroxide in the concrete pores than can be dissolved in pore water. This can help maintain the pH at its usual level of around 12 or 13 as the carbonation reaction occurs.

Photosynthesis - Wikipedia

2019-5-4 · Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms'' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek φῶς, phōs, "light", and σύνθεσις
