Compacting Factor test01:22

Compacting Factor test

778
The compacting factor test is a method used to assess the workability of concrete. It is  especially suitable for concrete mixes containing aggregates up to one and a half inches in size. This test involves specialized equipment consisting of two truncated cone-shaped hoppers and a cylinder, all with polished interior surfaces to minimize friction.
The procedure begins by placing concrete into the upper hopper without any compaction. Once filled, the bottom door of this hopper is opened,...

The Soil Ecosystem

17.5K
Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:

Microbial Bioremediation of Uranium01:25

Microbial Bioremediation of Uranium

114
Microorganisms play a critical role in the transformation and immobilization of uranium in contaminated environments through four main pathways: bioreduction, biosorption, bioaccumulation, and biomineralization. These mechanisms reduce uranium’s toxicity and prevent its migration through groundwater systems, offering sustainable approaches for in situ bioremediation.Bioreduction of UraniumBioreduction is driven by anaerobic bacteria such as certain strains of Geobacter and Shewanella,...

Slump Test01:20

Slump Test

1.8K
The slump test is a widely used method to measure the workability of concrete. It employs a 12-inch high truncated cone mold that tapers from eight inches at the base to four inches at the top. Before testing, the mold is securely attached to a flat base and dampened.
Concrete is poured into the mold in three layers to conduct the test. Each layer is compacted 25 times with a steel tamping rod, which has a five-eighths-inch diameter and a rounded end, to ensure even distribution and eliminate...

Microbial Leaching01:27

Microbial Leaching

238
Microbial leaching, also known as bioleaching, is an environmentally favorable method for extracting metals from low-grade ores using specific microorganisms. This biotechnological approach is particularly valuable for mining operations targeting copper, gold, and uranium, where traditional extraction methods may be economically or environmentally impractical.Copper Leaching and Microbial CatalysisIn copper bioleaching, crushed ore is arranged into heaps and irrigated with a dilute sulfuric...

Design Example: Maintaining Level of an Embankment

564
Constructing a roadway embankment over uneven terrain requires precise leveling to ensure stability and proper drainage. Surveyors use a leveling instrument and staff to calculate ground elevations and determine the required fill material at each point along the embankment alignment.The process begins by positioning a leveling instrument near a benchmark with a known elevation. A backsight reading establishes the instrument height, which serves as a reference for subsequent measurements. A...

Area of Science:

  • Environmental Science
  • Soil Science
  • Geotechnical Engineering

Background:

  • Surface mine reclamation in the U.S. mandates revegetation.
  • Soil compaction is a major obstacle to revegetation on Eastern U.S. coal mine sites with poor soil quality.

Purpose of the Study:

  • To assess the bulk densities of soils handled by bulldozers versus scrapers at a strip mine.
  • To compare field-compacted soil moisture-density relationships with those from Standard Proctor compaction tests.

Main Methods:

  • Field study at a strip mine site.
  • Measurement of soil bulk densities from soils spread by bulldozers and scrapers.
  • Determination of soil moisture-density relationships.
  • Comparison with Standard Proctor compaction test results.

Main Results:

  • Bulldozers and scrapers resulted in varying degrees of soil compaction.
  • Field compaction levels were analyzed against laboratory standards.
  • Identified that specific soil handling procedures influence compaction levels.

Conclusions:

  • The method of soil spreading (bulldozers vs. scrapers) impacts soil compaction.
  • Proper soil handling procedures are crucial for mitigating excessive compaction.
  • Reducing soil compaction can enhance the success of mine site revegetation efforts.
