Red Seal Concrete Finisher Practice Exam

Name one potential environmental concern when working with concrete.

1. Excessive water usage

2. Noise pollution during mixing

3. Cement production contributes to CO2 emissions

4. Increased local transportation requirements

The correct answer is: Cement production contributes to CO2 emissions

When discussing potential environmental concerns related to concrete work, the contribution of cement production to CO2 emissions is a significant issue. Cement, which is a key ingredient in concrete, undergoes a chemical process called calcination during its production. This process releases a large amount of carbon dioxide into the atmosphere, contributing to greenhouse gas emissions and climate change. The production of cement is responsible for approximately 5-8% of global carbon dioxide emissions. As industrial activities continue to increase and the demand for concrete rises due to urbanization and infrastructure development, this environmental impact becomes even more pronounced. Addressing cement production's CO2 emissions is crucial for promoting sustainability in the construction industry. Efforts to reduce these emissions include exploring alternative cement materials, implementing energy-efficient production techniques, and using carbon capture and storage technologies. Understanding this aspect fosters awareness and encourages practices that can mitigate environmental impacts associated with concrete finishing and construction in general.
