Green ConcreteConcrete industrys attempt to help reduce CO2 emission produced by concrete production

Global WarmingOne of the leading contributors to the production of CO2 emissions is the construction industry.Prior to 2000, public awareness of global warming was limited.Throughout the 2000s public awareness grew and action was taken.

Global Warming contdIn 2011 the Australian Prime Minister, Julia Gillard, introduced the Carbon Tax to reduce Carbon Dioxide emissions produced by Mining and Construction industry in Australia.Construction industry accounts for 30% of CO2 emissions.

Green ConcreteGreen Concrete is a concrete made up of a number of recyclable waste materials that form a hard composite rock like material that significantly reduce the CO2 emissions created by concrete

Waste MaterialsRecycled materials gathered from various specialised recycle plants.reduces the amount of natural resources taken from our environment.blast-furnace slag, a material gathered from steel production.fly ash, a waste material produced from coal combustion.

BenefitsLess CO2 emissions.Matching the structural strengths of common high strength concrete.Less heat of hydration.Less reduction and creep.Utilizes local recycled materials.

DisadvantagesSmaller life than conventional concrete.The split tensile strength being less than that of ordinary Portland concrete.Require more reinforcement.Recycled aggregates and materials in green concrete can cause corrosion in the steel reinforcement bars.

Green Concrete vs. Portland ConcreteHow do they compare?

Mechanical PropertiesSustainable green concrete mechanical strength properties are almost identical, and sometimes match that of conventional Portland concrete

Green Concrete?So, is it feasible in high-rise design?

FeasibleCurrently, best solution for concrete material in regards to CO2 emissions.Green concrete has limitations as to how it can be applied in certain situations and environments.Further research needs to be conducted into the material.

Green concrete is a material, if utilized to its potential, could help greatly reduce the construction industrys Carbon Dioxide impact on the planet and create structures all over the globe.
