All the companies that produce cement have environmental management systems in place and programmes to minimize the environmental impact from mining activities. It is estimated by BRE's Green Guide that 50% of concrete is crushed and recycled, 40% is down cycled for use such as hardcore in substructure works or road construction and the ...

Although resource scarcity and pollutant emissions are recognized as important environmental issues facing the cement and concrete industry, the most commonly discussed environmental impact is the ...

Cement and global warming • Making cement results in high levels of CO 2 output. • Cement production is the third ranking producer of anthropogenic (man-made) CO 2 in the world after transport and energy generation. • 4 - 5% of the worldwide total of CO 2 emissions is caused by cement production. • CO 2 is produced at two points during cement production :

Replacing fossil fuels with renewable energy sources and raising efficiency across production could reduce the carbon footprint by up to 40 percent. Using different raw materials for clinker could...

In this article, I'll delve into the environmental implications of concrete use. Here's what you'll learn: The carbon footprint of concrete production; How concrete affects …

Concrete has many environmental advantages, including durability, longevity, heat storage capability, and (in general) chemical inertness. For passive solar applications, concrete's ability to function as a structural element …

Advancement in 3D-printed concrete promises strength, durability and lower carbon emissions Date: October 25, 2024 Source: University of ia School of Engineering and Applied Science

Sustainable concrete construction is a step towards green and eco friendly concrete construction practices to solve global environmental problems. Concrete is a construction material which has been used substantially all over the world.

Utilizing high-volume fly ash waste (FA) as a cement replacement will contribute to a reduction in the environmental problems related to cement production and landfill disposal. It is well known that the inclusion of high amounts of FA (up to 50%) as a cement replacement leads to low strength performance, especially at a concrete's early age ...

The concrete industry is a major carbon emitter and polluter, with severe human health impacts. But circular solutions, including electrifying cement plants, making low-carbon cement, and bio ...

Attention is often devoted to intensive animal farming, fossil fuels, and plastic waste as big problems. In the coming decades, we need all sectors of society to decarbonize. That should include infrastructure development, and thus concrete. This article explores the definitions of green concrete and the environmental impacts of traditional ...

With rapid economic development, the resulting environmental problems can not be ignored including the concrete batching plant environmental issues. Starting from the problems existed in the traditional batching plant, the following puts forward the concrete batching plant environmental issues and the corresponding improvement and protection ...

As the world strives to find more sustainable solutions for construction, it's crucial to examine the environmental impacts of concrete construction and manufacturing, and explore potential methods for mitigating these issues. ‍ In …

The waste management sector is crucial for protecting the environment, conserving resources, and promoting sustainable development by ensuring efficient disposal, recycling, and minimizing the harmful impact of waste. This study aims to understand the performance levels (compressive strength), environmental impact, and overall sustainability of …

In addition, concrete has durability problems due to bleeding [25], honeycombing [26], alkali-silica reaction [27], steel corrosion [28], efflorescence [29], and heterogeneity of the materials [30 ...

Another environmental issue with cement and concrete production is water pollution. The concern is the greatest at the concrete production phase. ... While the cement and concrete industries can help reduce some of our solid waste problems (burning hazardous waste as cement kiln fuel and using fly ash in concrete mixtures, for example), one ...

"While concrete is the most commonly used construction material on earth, it is also the biggest in terms of environmental impact," said Yahya "Gino" Kurama, a professor of civil and environmental ...

Roughly 40% of the greenhouse-gas emissions associated with cement production come from fossil fuels that generate the heat required. This is a common problem across heavy industry: fossil fuels ...

Concrete is among the world's most consumed materials—second only to water. 1 That's because its durability, affordability, and availability make it essential to countless construction projects, from bridges, to roads, to buildings. Since concrete is used on such a large scale, it also produces large amounts of heat-trapping greenhouse gases, mostly from a …

Texas Texans affected by pollution from concrete batch plants push state agency to tighten regulations. As the state's environmental agency weighs new pollution limits on the plants, several ...

Concrete is createdby mixing a binding mass, either cement or lime, with fine or coarse aggregates (like stone, gravel or sand) and water. The cementis a manufactured mixture of materials that includes calcium, silicon, aluminium and iron, among other ingredients. While concrete has been …
