ANALYSIS OF THE HEAT RESISTANCE AND DURABILITY OF TREATED MUNICIPAL SOLID WASTE ASH IN BUILDING MATERIALS
Appropriate handling of this material is crucial since the growing amount of treated municipal solid waste ash has been a major burden on society. PMSWA was used as the raw source in this investigation to create autoclaved wall blocks based on solid waste. To make SW-Bricks more durable, three admixtures were separately applied, and the effects on shrinkage, water absorption, heat conductivity, and frost resistance were extensively studied. Researchers were able to comprehensively examine the microscopic process by combining XRD analysis. The results of the experiment show that after drying for 40 and 140 days, the reduction in size of SW-Bs with NaCl decreases by 80.2% and 20.6%, respectively. On the other hand, NaNO3 and NaOH both increase drying distortion, which is bad for SW-Bs' endurance. The pore structure of the system is improved by Cl_ promoting the synthesis of Al-substituted tobermorite, which is why NaCl significantly reduces mass loss and power in terms of frost resistance.The 28-day goal strength was satisfied by the solid waste ash concrete's compressive strength for all ash replacement ratios between 6 and 29%. The pore architectures of SW-Bs mixing with NaNO3 and NaOH are comparable, mostly consisting of a single distribution of mesopores. As a result, there was little resistance to frost and a relatively high-water absorption. When it comes to thermal conductivity, NaCl outperforms NaNO3 and NaOH in terms of helping SW-Bs retain heat. This study is a helpful tool for improving the toughness of SW-Bs manufactured from treated solid waste ash and appropriately recycling PMSWA.
