The sand fraction originally present in crushed C&D waste represents around 50% of the total waste. This paper presents a technology that permits the production of high quality recycled sand. The total comminution of C&D waste made possible the production of low porosityCited by: 50
from recycled concrete supply roughly 5 percent of the total aggregates market (more than 2 billion t per year), the rest being supplied by aggregates from natural sources such as crushed stone, sand

Recycled Crushed Glass as natural Sand Replacement The 35MPa mix using 45% recycled crushed glass, has a slightly lower slump than the control, with the air content also slightly lower than control.
Research was conducted to determine the feasibility of using recycled rubber tires in the production of asphalt in Alaska. Employees of the Departments of Transportation in Arizona, California and Florida were contacted to determine the best practices of those states in the production of asphalt using crumb rubber, a product of ground recycled rubber tires. Because of the similarity of climate
The practical use of recycled concrete aggregate produced by crushing concrete waste reduces the consumption of natural aggregate and the amount of concrete waste that ends up in landfills.Published in: Construction and Building Materials · 2013Authors: Carina Ulsen · Henrique Kahn · Gustav Hawlitschek · E A Masini · Sergio Cirelli AnguloAffiliation: University of Sao Paulo · Museo Nacional Del PradoAbout: Mineral processing
In addition, the focus on the production of recycled sand as a main product is unusual, but the results shown herein confirm that this approach might be interesting in diversifying the recycled products and thus expanding the recycling market.Cited by: 50

sand production in weak consolidated formations. Optimized perforating techniques, based on enhanced risk assessment, can delay or avoid sand production over a well's productive life. As one of the screenless completion methods, optimized perforating can help prevent production of sand from within the formation.

production sites can produce aggregates for concrete, such as washed sand, but this is less widespread. The WRAP specifier tool has details of the different aggregate types.
Production Mirjana Male Recycled aggregate was made by crushing the waste concrete of laboratory test cubes and precast concrete columns. Three types of concrete mixtures were tested: concrete made entirely with natural aggregate (NAC) as a control concrete and two types of concrete made with natural fine and recycled coarse aggregate (50% and replacement of coarse recycled aggregate
Using Recycled Industrial Materials in Buildings Greening the built environment.
