A hydraulic breaker creates concrete rubble.. Rubblization is a construction and engineering technique that involves saving time and transportation costs by reducing existing concrete into rubble at its current location rather than hauling it to another location.
The pieces can be shaped, for example using a chisel; this can be labor-intensive. Crushing involves removing trash , wood and paper ; removing metals such as rebar , using magnets and other devices, to be recycled separately; [ citation needed ] sorting the aggregate by size; crushing it using a crushing machine ; and removing other ...
Caliche fossil forest on San Miguel Island, California. Caliche (/ k ə ˈ l iː tʃ iː /) (unrelated to the street-slang "Caliche" spoken in El Salvador) is a soil accumulation of soluble calcium carbonate at depth, where it precipitates and binds other materials—such as gravel, sand, clay, and silt.
Recycled glass aggregate crushed to a small size is substituted for many construction and utility projects in place of pea gravel or crushed rock. Glass aggregate is not dangerous to handle. It can be used as pipe bedding—placed around sewer, storm water or drinking water pipes to transfer weight from the surface and protect the pipe.
Each white lump marks the top of a deep ground-freezing tap. Cross section of a ground freezing pipe as used in the Big Dig. Ground freezing is a construction technique used in circumstances where soil needs to be stabilized so it will not collapse next to excavations, or to prevent contaminants spilled into soil from being leached away.

This can be observed at the surface as effects known alternatively as "sand boils", "sand blows" or "sand volcanoes". Such earthquake ground deformations can be categorized as primary deformation if located on or close to the ruptured fault, or distributed deformation if located at considerable distance from the ruptured fault.

This story is the first in a series about what can happen to people on the ground when the World Bank bankrolls big projects. Other stories published today by HuffPost and ICIJ include an overview detailing the reporting team’s key findings , a look at mass evictions in Ethiopia tied to a World Bank project and an examination of a Peruvian ...
The term hard landscape is used by practitioners of landscape architecture and garden design to describe the construction materials which are used to improve a landscape by design. The corresponding term soft landscape materials is used to describe vegetative materials such as plants, grasses, shrubs, trees, etc. to improve landscape or outdoor ...
