Aug 01, 2019· Jaw Crusher, also known as concrete crusher, is usually used as the primary equipment for concrete crushing. It is also suitable for metallurgy, mining, construction, chemical, water conservancy and railway sectors, and used as a device for fine and medium crushing of ores and rocks with compressive strength below 250 Mpa.

Crushing Behavior and Crushing Strengths of Low-Density ...

According to the results presented in Table 6, in scenario 1, the major consumer of energy is the crushing phase (step 2), which has caused a significant increase in total energy consumption, yet the CO 2 emission produced due to extraction phase (step 1) is greater than the amount produced due to crushing phase.

4 Environmental benefits to using green concrete ...

Mar 29, 2017· • RCA concrete tends to leach higher levels of metals than conventional concrete • Leachability of metals depends on type of metal, pH, carbonation, and mobility characteristics (Galvin et al. 2014) 27 Use of RCA in concrete mixtures mitigates water quality issues associated with leaching.

ENVIRONMENTAL IMPACT OF CONCRETE RECYCLING, …

Limestone crushing plant: it is used to produce sand and aggregates. Basalt crushing plant: the sand made of basalt can be mixed with concrete to reduce the weight of concrete and at the same time maintain the strength. It also has the features of sound insulation and heat insulation, making it ideal for high-rise building construction.

Cement and Concrete Sustainability

• Of the total CO 2 output, 30% derives from the use of energy and 70% results from decarbonation • Important to realise is that although 5% of the worldwide generation of CO 2 is due to cement production, that level of output also reflects the unique and universal importance of concrete throughout the construction industry.

Crushing and Liberation of Materials by Electrical ...

paper presents a method of electrical crushing (disintegration) to liberate minerals. Conventional crushing and grinding equipment breaks the materials into a random pattern from rocks, concrete and waste electric tools, and results in a high consumption of energy. Instead of

Stationary Crushing Plant | Stationary Crushing ...

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 recycling - Wikipedia

Jun 30, 2011· Recycled concrete qualifies for recycled material credits, and because it usually is found locally, it qualifies for local credits. • Concrete with recycled concrete aggregate has a smaller carbon footprint. • Crushing old concrete to produce aggregate takes less energy than mining aggregate.

concrete crusher consumption

This measure suggests that a VSI can save 2–14% of the energy consumed in grinding, depending on the energy model used and the final product size. This estimate is in agreement with an energy saving of 11.8% observed in an iron ore application where VSI's were introduced as a crushing …

Sustainability of Concrete Construction

Under compression, the microstructure of low-density foam concrete gets progressively crushed at a steady stress stage, accompanied by substantial energy dissipation. Understanding foam concrete crushing behavior is of special importance for its engineering applications.
