How much of our waste comes from construction?

600 million tons of C&D debris were generated in the United States in 2018, which is more than twice the amount of generated municipal solid waste. Demolition represents more than 90 percent of total C&D debris generation, while construction represents less than 10 percent.

Why is waste management important in construction?

How does construction affect soil?

1) All soil is vulnerable to erosion. And during the construction process, soil becomes loose and loses its stability. To help decrease any problems caused by erosion, one method is limiting the space where the soil is moved around during the excavation process, explained in Site Engineering for Landscape Architects.

Which type of soil is suitable for construction?

Sand. It is most extensively used construction material. It consists of particles of rock and hard minerals, such as silicon dioxide. They are the largest type of soil particles, where each particle is visible to naked eye.

Is sandy soil good for construction?

Is clay soil good for construction?

Building foundations need to be on stable and strong soils. ... The strength and stability of soil depend on its physical properties. Soil with good structure is more stable. Clay textures are often more stable than sand textures because they have better structure.

How do you classify soil?

Soils can be classified as Type A, Type B, or Type C. Type A soil is the most stable soil in which to excavate. Type C is the least stable soil. It's important to remember that a trench can be cut through more than one type of soil.

What is the most basic classification of soil?

The USCS has three major classification groups: (1) coarse-grained soils (e.g. sands and gravels); (2) fine-grained soils (e.g. silts and clays); and (3) highly organic soils (referred to as "peat"). The USCS further subdivides the three major soil classes for clarification.
