Is Portland cement bad for the environment?
Today, many construction companies and concrete manufacturers have cut the use of Portland cement in their mixtures due to its production process emitting significant amounts of greenhouse gases into the atmosphere.
Why Portland Cement has an impact on environment?
It is used in our roads, dams, bridges, and buildings because of its versatility, strength, and durability. Yet producing the portland cement that binds concrete together is energy intensive and emits enormous amounts of carbon dioxide (CO 2) as well as numerous other pollutants.
What is the environmental impact of making cement?
The environmental impacts of concrete production go beyond CO2 emissions and climate change. Impacts can include acid rain as a result of emissions of sulphur dioxide, nitrogen dioxide and nitric oxide; health risks of locally high concentrations of cement kiln dust, and the depletion of drinking water supplies.
What is ordinary Portland cement concrete?
Ordinary Portland cement (simply called ordinary cement) refers to the hydraulic binding material ground by mixing Portland cement clinker, 6% ~ 15% blended materials, and appropriate amount of gypsum, code-named P• O.
What is the most eco friendly material to build a house?
Bamboo. Sustainability experts nearly universally agree bamboo is one of the best eco-friendly building materials on the planet. Its rate of self-generation is incredibly high, with some species growing up to three feet in 24 hours.
How much does cement contribute to global warming?
But its popularity comes at an environmental cost –the production of concrete, which is made with cement mix, contributes about eight percent of all carbon dioxide emissions worldwide.
How can we reduce the environmental impact of concrete?
New technologies and approaches are being developed to cut down on concrete’s environmental downsides — everything from utilizing industrial by-products to reduce cement usage, to recycling existing concrete, to producing self-healing concretes that reduce the need for new concrete, to creating entirely new materials.
What is the use of ordinary portland cement?
Its uses include pavements and sidewalks, reinforced concrete buildings, bridges, railway structures, tanks, reservoirs, culverts, sewers, water pipes and masonry units.
