Chapter 12, Problem 12.6PAE

Interpretation Introduction

Interpretation:

The chemical reaction involved in the carbonation of concrete should be explained.

Concept Introduction:

• Concrete is a mixture of cement, water and other additives that are mixed in order to produce concrete with the desired composition and characteristics.
• Production of concrete releases CO₂ into the atmosphere where weathering or hardening proceeds with the absorption of CO₂
• Carbonation generally involves reactions of carbon dioxide to form carbonates, bicarbonates or carbonic acid.
