Energy Consumption in Production of Concrete

Aug 28, 2017  The production of 1 m³ of concrete requires 2,775 MJ of energy. This energy comes mostly from oil burning , which generates CO2. 2.775 MJ of energy is produced by 0.37 barrels of oil . Saving concrete, e.g. by adopting appropriate building solutions, means therefore not only reducing fossil fuels consumption, but also pollutant emissions.

Concrete - Energy Consumption - Green Building Central

Dec 05, 2020  For every ton of cement produced, approximately 2,400 pounds of carbon dioxide are released. Carbon dioxide emissions from the production of concrete stem from two primary sources: the energy used in the production of cement and the chemical process of calcining limestone into cement (CaCO3 -> CaO + CO2). Each is a major contributor (Table 2).

where E i is the energy use per year for material ‘i’ (J), Q i is the material production per year (mass), and e i is the energy intensity (MJ kg −1).Our total energy use then is just the sum E T =ΣE i.. First, we look at the energy intensity of material production (e) and review the reasons for the high values and the steps that can be taken to reduce these values.

Concrete - Wikipedia

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past, lime based cement binders, such as lime putty, were often used but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (named for its visual ...

The fracture energy Gf can be determined following a RILEM recommendation. However, it has been found that fracture energy depends on both size and geometry of the test specimen. The underlying fictitious crack model postulates that fracture energy, tensile strength, the critical opening of the fictitious crack, and the shape of the softening curve (softening factor) are constants for a given ...

Insulating Concrete Forms (ICFs)

Insulating concrete forms (ICFs) result in cast-in-place concrete walls that are sandwiched between two layers of insulation material. These systems are strong and energy efficient. Common applications for this method of construction are low-rise buildings, with property uses ranging from residential to commercial to industrial.

Embodied energy YourHome

Gross energy requirement (GER) is a measure of the true embodied energy of a material, which would ideally include all of the above and more. In practice this is usually impractical to measure. Process energy requirement (PER) is a measure of the energy directly related to the manufacture of the material. This is simpler to quantify.
