AI Technical Summary
Existing technologies lack rapid and quantitative methods for determining the degree of carbonization of calcium-based alkaline solid waste, resulting in long experimental cycles and high costs, making it difficult to efficiently screen out the optimal carbonization conditions suitable for the entire solid waste gelation system.
By measuring the relationship between the mass fraction of Ca(OH)2 and the carbonization time at different carbonization times, and combining this with the strength changes of cementitious materials under different mix proportions, a curve showing the relationship between the mass ratio of Ca(OH)2 and the strength was established, allowing for the rapid determination of the optimal carbonization time.
This method enables the rapid and low-cost determination of the optimal carbonization degree of calcium-based alkaline materials in a solid waste cementing system without the need for long-term mechanical testing, significantly reducing the workload of experiments and R&D costs.
