Cotton textile waste (CW) and crushed bricks (CB) are wastes generated by the textile and construction industries that cause adverse effects on the environment. This paper explores the effect of adding 1, 2, 5, and 10 wt.% of CW and CB, instead of natural sand under 1 mm (50 to 100 vol.%), on the properties of concrete. The study included …
Leaching assessment of aerated concrete made of recycled shale gas drilling cuttings: Particular pollutants, physical performance and environmental characterization

Sector C: Chemical and Allied Products Manufacturing and Refining. is a written assessment of potential sources of pollutants in stormwater runoff and control measures that will be implemented at your facility to minimize the discharge of these pollutants in runoff from the site. These control measures include site-specific best management ...
This made it difficult to differentiate the fractions of potential pollutants coming from RAP and soil. Natural weathering processes by sunlight, air and precipitation typically oxidize the major components of asphalt and hence result in the release of toxic compounds into aqueous phase.
Currently, crushed concrete is often either stockpiled in construction and demolition heaps 127 or reused as road subbase or in new concrete, both of which reduce its carbonation …
This paper presents the residual mechanical properties of concrete made with crushed bricks and clay roof tile aggregates after exposure to high temperatures. One referent mixture and eight mixtures with different percentages of replacement of natural aggregate by crushed bricks and roof tiles are experimentally tested.
Asphalt is a significant source of air pollutants in urban areas, especially on hot and sunny days, researchers report.
Recycled concrete aggregates (RCA) are used in existing green building composites to promote the environmental preservation of natural coarse aggregates (NCA). Besides, the use of RCA leads to potential solutions to the social and economic problems caused by concrete waste. It is found that insufficient information on the longevity and …
Where feasible, minimizing exposure of potential pollutant sources to precipitation is an important control option. Minimizing exposure prevents pollutants, including debris, from coming into contact with precipitation and can reduce the need for BMPs to treat contaminated stormwater runoff.
Crushed concrete offers cost-effective and eco-friendly benefits for driveways. By repurposing recycled materials, it reduces expenses compared to fresh concrete or natural stone. This choice not only saves money but also contributes to sustainability by minimizing landfill usage.
The cost of crushed concrete is subject to variation, influenced by factors such as demand, quantity, delivery distance, and the choice of supplier. This section explores the dynamics behind the pricing of crushed concrete and provides insight into navigating the market for …
BMPs for Potential Pollutant Sources at Automobile Salvage Yards. Installation of a consolidated processing area, including a covered and bermed impermeable concrete surface equipped with a drain, where all fluids are drained. Fluid and Parts Removal Drain all fluids from vehicles upon arrival at the site.
Other potential sources of pollutants at landfills and land application sites include those from ancillary areas and areas which are not directly associated with landfill or land application activities (e.g., vehicle maintenance, truck washing).
A primary source of pollutants in the stormwater discharges from glass, clay, cement, concrete, and gypsum product manufacturing facilities are spilled materials or settled dust from material handling processes.
Some of the most commonly available recycled materials are crushed concrete (CC) and recycled asphalt pavement (RAP), and these materi-als are being considered for use as backfill in MSE walls in Texas. This Project Summary Report (PSR) summarizes the results from the Texas Department of Transporta-tion (TxDOT) Project 0-4177, as related to the ...
Pollutants conveyed in stormwater discharges from scrap recycling and waste recycling facilities will vary. There are a number of factors that influence to what extent industrial activities and significant materials can affect water quality.
The results of this study point to the significant potential of combining FA and GGBS at an optimum ratio to mitigate the ASR effect on RCA concretes containing crushed glass sand. This approach helps in minimizing the emission of greenhouse gases and other pollutants generated during cement production, thereby mitigating …
Building materials in the construction industry, particularly concrete and cement, are one of the parameters that cause an increase in global CO2 emissions. Cement production is responsible for 5–8% of these emissions, being a key factor in global warming potential (GWP). This underscores the need for scholarly attention to the …
This study provides an overview of how phase change materials (PCMs) can improve the resistance of concrete pavement to freeze–thaw cycles and mitigate the urban heat island (UHI) effect. The investigation covers different types of PCMs and methods for integrating them into concrete pavement, as well as the mechanical properties and …
The chemical behaviour of several pollutants in cement matrix is explained and examples of results obtained by leaching studies on concrete materials are discussed.
Where feasible, minimizing exposure of potential pollutant sources to precipitation is an important control option. Minimizing exposure prevents pollutants, including debris, from coming into contact with precipitation and can reduce the need for BMPs to treat contaminated stormwater runoff.
Pollutants conveyed in stormwater discharges from facilities involved with the manufacturing of glass, clay, cement, concrete, and gypsum product will vary. There are a number of factors that influence to what extent industrial activities and significant materials can affect water quality.
In addition, this work reveals the spatial characteristics of pollutant emission level and emission reduction potential of the cement industry, which is conducive to the rational layout of ultra-low emission transformation, and push forward the transformation task by area and stage.
The improvement potential of initiatives proposed in literature to reduce the environmental impact of concrete and asphalt is translated into scenarios, which are evaluated from three perspectives in Section 5. Finally, Section 6 states the conclusions, while suggestions for further research are given in Section 7. 2.
In the present study, first, the environmental challenges and cracking characteristics during the construction of plateau concrete on the Sichuan–Tibet route were revealed. Then, …
The exploitation of secondary- or waste materials in production processes has therefore a great potential which is not related solely to binders but also to fillers. In this light, this paper aims at thorough investigations of concrete mixtures with crushed concrete pavements as partial or full replacement of natural coarse aggregates.
