Summary
Managing engineering and decoration waste is crucial due to rapid urban development. This study proposes a comprehensive system for waste generation, collection, transportation, and disposal to mitigate environmental risks and improve management strategies.
Area of Science:
- Environmental Science
- Urban Planning
- Waste Management
Background:
- Rapid urbanization generates substantial engineering and decoration waste, posing significant environmental risks.
- Current disposal methods, primarily landfilling, consume land and cause pollution.
- Existing issues include irregular waste emissions, a disorganized transport market, and insufficient disposal facilities.
Purpose of the Study:
- To develop a comprehensive management system for engineering and decoration waste.
- To address challenges in waste generation, collection, transportation, and disposal.
- To propose a propagable strategy for improving waste management in urban environments.
Main Methods:
- A hybrid approach combining site visits, interviews, expert seminars, and desktop surveys.
- Determining waste emission and disposal requirements through on-site assessments.
- Identifying suitable management practices and developing a system with three core modules.
Main Results:
- New buildings generate significant waste: 0.02-0.04 m³ of construction waste and 0.11-0.13 m³ of decoration waste per m² of building.
- Identified issues such as illegal dumping and the need for emission limits and directed transportation.
- Highlighted the necessity for a clear responsibility mechanism and government-authorized operations.
Conclusions:
- A structured, three-module system (generation, collection & transportation, disposal) is proposed for effective waste management.
- Implementation requires clear responsibilities and potential government authorization for construction and operation.
- The proposed system offers a propagable strategy to enhance engineering and decoration waste management.

01:24Design Example: Aggregate Gradation
154
The right type and quality of aggregates are crucial for concrete as they significantly influence its properties, mix proportions, and cost-effectiveness. If different sources are available for sand, the commonly used fine aggregate in concrete, the selection of sand is primarily based on its gradation.
The grading, or particle-size distribution, of sand is determined using sieve analysis, with standard sizes ranging from 150 μm to 10 mm (ASTM No. 100 sieve to 3⁄8 in. sieve). Sand is...

01:14Design Example: Managing Concrete Workability
125
This example deals with managing the workability of concrete for a raft foundation project under hot weather conditions. Workability is crucial for ensuring the concrete is easy to place, compact, and finish. In this scenario, a slump test — a common method to measure the workability of fresh concrete — initially indicated low workability. This was attributed to the rapid water loss from the concrete mix, exacerbated by the high temperatures causing the course aggregates to heat up.

01:19Design Example: Maintaining Level of an Embankment
139
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...

01:25Deleterious Substances in Aggregate
275
Deleterious substances in aggregates can be detrimental to the quality and durability of concrete. These substances include organic impurities like loam, which interfere with cement hydration and are usually present in the sand. These prevent a good bond between aggregate and cement paste. Organic impurities can be detected using the colorimetric test, where the darkness of a solution after agitation indicates the level of organic content.
Another type of impurity is clay and fine material that...
