On-site Polymer Binder Construction for Remote Sites
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional construction methods for temporary or remote structures are costly, time-consuming, and require significant equipment and material transportation, making them impractical for areas with limited infrastructure, especially where water is scarce and traditional concrete production is challenging.
Innovation Solution
A method using a structural mix formed from locally sourced aggregate material and a no-bake polymer binder, which can be mixed on-site with additives to create a self-hardening material for constructing temporary or permanent structures, reducing the need for extensive planning and transportation of materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional concrete is used for construction, then structural strength is improved, but construction time and material transportation cost increase significantly
Solution Approach 1:
The construction process is segmented into two independent phases: (1) mixing aggregate with polymer binder on-site to create green strength material, and (2) subsequent thermal curing to achieve final strength. This segmentation allows the structure to gain initial strength quickly on-site without waiting for off-site concrete production and transportation, resolving the contradiction between strength development and construction time
Solution Approach 2:
The polymer binder is applied to the aggregate on-site before thermal curing, creating immediate green strength that allows the structure to bear loads during the curing process. This preliminary action eliminates the need to wait for complete concrete curing before use, significantly reducing construction time while maintaining structural integrity
2Strength
If traditional concrete is used for construction, then structural strength is improved, but equipment and material transportation requirements increase
Solution Approach 1:
The water component is extracted from the traditional concrete mixture and replaced with polymer binder. This extraction eliminates the need for large quantities of water transportation to remote sites and allows the use of locally available aggregate material, significantly reducing equipment and material transportation requirements while maintaining structural strength through the polymer bonding mechanism
Solution Approach 2:
The system uses locally available aggregate material at the construction site rather than requiring imported cement and water. The polymer binder serves as a self-contained binding agent that doesn't require external water sources, enabling the construction process to be self-sufficient in remote locations without extensive infrastructure
3Productivity
If polymer binder is used instead of cement, then construction speed and on-site flexibility are improved, but material cost increases
Solution Approach 1:
The construction process utilizes thermal curing by applying heat to accelerate polymer binder curing, reducing the waiting time from days to hours. This parameter change (temperature acceleration) dramatically improves construction speed and allows rapid deployment while the polymer binder's efficient bonding reduces the overall material quantity needed compared to traditional concrete mixes

AI summary
A structural building system and method for forming and using a structural element at a building site using a structural mix comprised of an aggregate material sourced exclusively from the building site, a no-bake binder, and a strengthening additive. According to the method disclosed herein, aggregate material is sourced exclusively from a supply of aggregate material located at a building site. A no-bake binder is combined with the aggregate material in a mixer to form a structural mix at the building site. Finally, the structural mix is deposited at a deposit site and is allowed to self-harden to form a structural element.
