Worldwide, precast concrete elements are becoming the primary construction materials, and there have been conducted numbers of studies on their manufacturing process, mechanical properties and curing regime. However, the energy consumption of the precast concrete manufacturing process and specifically the curing process is ignored by researchers. …

The need for washing and drying the concrete waste prior to the magnetic separation was found to be the bottleneck of the RC production process in terms of energy consumption (Bogas and Sousa 2021; Sousa et al., 2021, 2022). The high energy consumption is driven not so much by the amount of water to be removed, but by the fact that a large ...

Optimization of energy consumption during mixing using admixtures in concrete manufacturing is the predominant focus of this article. To achieve this objective, power consumption data were...

The production of cement is an energy-intensive process. Typically, energy consumption accounts for 20-40% of production costs. In 2008, the U.S. cement industry spent about $1.7 billion to …

This leads to differences in concrete energy consumption. The power consumption during mixing is divided into different stages. The first stage starts from an empty condition and proceeds to the loading condition. ... Beitzel, H. Optimisation of the Mixing Process for Producing SCHP Concrete; RILEM Bookseries; Springer: Berlin/Heidelberg ...

However, the process of mixing concrete is energy-intensive and exerts significant wear and tear on the mixing blades, leading to maintenance costs and environmental concerns.

Cement is the main binder in the production of concrete for construction activities. Unfortunately, the continuous use of cement results in severe environmental and energy concerns.

Sixty percent of the on-site emissions associated with this step are process emissions–coming from the chemical decomposition of limestone (CaCO 3 –> CaO + CO 2) in the kiln. The rest come from the combustion of fossil fuels to reach the high temperatures required for the process.

The process of concrete production begins with the selection and preparation of aggregates, which typically include sand, gravel, crushed stone, or recycled materials. Aggregates are carefully graded to achieve the desired strength, ... Cement production is known for its high energy consumption, which occurs during various processes such as raw ...

focus on the impact of admixtures on power consumption during concrete mixing, thereby reducing energy consumption in concrete production in ready-mixed concrete plants. The workability test is also conducted for comparison with the power consumption curve. The power consumption during the mixing process also depends on the flow of the concrete;

In industrialized countries, primary energy consumption in a typical cement plant is up to 75% fossil fuel and up to 25% electrical energy using a dry process. Pyro-processing …

Moreover, input pressure could commendably affect the process energy consumption since too low negative inlet pressure influences the steady gas flow within the system and disturbs the grinding ...

This paper presents the measurement and analysis of energy consumption of a laboratory jaw crusher during concrete recycling. A method was developed to estimate the power requirements of a lab ...

The production of cement is an energy-intensive process. Typically, energy consumption accounts for 20-40% of production costs. In 2008, the U.S. cement industry spent about $1.7 billion to purchase energy; around $0.75 billion of this was for electricity and $0.9 ... concrete, which is a combination of cement, mineral aggregates and water ...

Energy consumption in the production of concrete Table 3 shows the energy consumption in the production of ready-mixed concrete. A case study of C20: (1) Energy consumption in the aggregate preparation: M sand+gravel×28 kWh/ton×12.4 MJ = 675 MJ; (2) Energy consumption in the production of cement: M cement× Energy consumption=0.24×3130 kg ...
