  2. Environmental impact of concrete - Wikipedia

    en.wikipedia.org/wiki/Environmental_impact_of...

    The CO 2 emission from the concrete production is directly proportional to the cement content used in the concrete mix; 900 kg of CO 2 are emitted for the fabrication of every ton of cement, accounting for 88% of the emissions associated with the average concrete mix.

  3. Fiber-reinforced concrete - Wikipedia

    en.wikipedia.org/wiki/Fiber-reinforced_concrete

    The following are several international standards for fiber-reinforced concrete: [35] BS EN 14889-1:2006 – Fibres for Concrete. Steel Fibres. Definitions, specifications & conformity; BS EN 14845-1:2007 – Test methods for fibres in concrete; ASTM A820-16 – Standard Specification for Fiber-Reinforced Concrete (superseded)

  4. Carbon price - Wikipedia

    en.wikipedia.org/wiki/Carbon_price

    Latest models of the social cost of carbon calculate a damage of more than $300 per ton of CO 2 as a result of economy feedbacks and falling global GDP growth rates, while policy recommendations range from about $50 to $200. [7]: 2 Many carbon pricing schemes including the ETS in China remain below $10 per ton of CO 2. [3]

    In the form of boric acid, price per boron contained. Min. 99% pure. 6: C: Carbon: 2.267: 200 (5.54 × 10 18 kg) 0.122: 0.28: 2018: EIA Coal [19] In the form of anthracite, price per carbon contained, assuming 90% carbon content. There is a wide variation of price of carbon depending on its form.

    Controversially, in 2006, cricket bats with a thin carbon-fiber layer on the back were introduced and used in competitive matches by high-profile players including Ricky Ponting and Michael Hussey. The carbon fiber was claimed to merely increase the durability of the bats, but it was banned from all first-class matches by the ICC in 2007. [37]

  7. Social cost of carbon - Wikipedia

    en.wikipedia.org/wiki/Social_cost_of_carbon

    The price being set for the social cost of carbon is dependent upon the administration in charge. While Obama was in office, the administration paved the way for the first estimate of putting a price on carbon emissions. The administration estimated that the cost would be $36 per tonne in 2015, $42 in 2020, and $46 in 2025. [17]

  8. Embodied energy - Wikipedia

    en.wikipedia.org/wiki/Embodied_energy

    Embodied energy is the sum of all the energy required to produce any goods or services, considered as if that energy were incorporated or 'embodied' in the product itself. . The concept can be useful in determining the effectiveness of energy-producing or energy saving devices, or the "real" replacement cost of a building, and, because energy-inputs usually entail greenhouse gas emissions, in ...

    The other boat was constructed using carbon fiber fabric as its method of reinforcement. The boats competed in the 1996 Concrete Canoe Regatta in Dresden, Germany, and this was the first time that textile-reinforced concrete was brought to public attention; the boats received an award for their design.
