Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to effectively convert and utilize finely divided materials, such as those with high clay content, into coarser aggregates with tailored particle size and mechanical properties for construction applications, leading to waste and environmental issues.
Innovation Solution
A method involving mixing finely divided materials with a binder and water, adding an agglomerating agent, and controlling the mixing process to produce aggregates with specific properties, allowing for the reuse of materials that would otherwise be disposed of.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If fine aggregate is washed to reduce fine particles content, then the properties of the final product are improved, but water consumption increases and environmental problems occur
Solution Approach 1:
The invention changes the particle size distribution parameters of the fine aggregate by controlled drying to reduce fine particles content below 5%, transforming the material properties to meet construction requirements without washing
Solution Approach 2:
The invention extracts and removes fine particles through controlled drying and sieving processes, separating them from the aggregate to achieve the desired particle size distribution for construction applications
2Manufacturing precision
If fine aggregate with high content of smaller particles is disposed of, then the quality of remaining aggregate is maintained, but material waste increases
Solution Approach 1:
The invention transforms the particle size distribution of fine aggregate through controlled drying, converting material that would be discarded into usable construction aggregate by achieving the required fine particles content below 5%
Solution Approach 2:
The invention converts fine aggregate with excessive fine particles (which would normally be waste) into a valuable construction material by applying controlled drying treatment to achieve the desired particle size distribution
3Ease of operation
If permeable pavement is constructed with high fines content, then workability is improved, but water infiltration capability is reduced
Solution Approach 1:
The invention changes the particle size distribution parameters of the aggregate to achieve fine particles content below 5%, creating optimal conditions for both workability and water infiltration in permeable pavement applications

AI summary
Method to artificially agglomerate finely divided materials. A method to agglomerate finely divided material into aggregates, the aggregates being larger than the finely divided material, comprising the steps of (a) mixing finely divided material, binder and water in a mixer, (b) adding an agglomerating agent to the mix formed in step (a) and mixing constantly. Finely divided material is selected from the group consisting of cement, sand, clay, glass, slag, fly ash, stone powder, bypass dust, limestone, silica fume, crushed brick, brick powder and crushed stone or a combination thereof.
