Summary: This paper presents a novel kaolinite-based porous geopolymer composite thermal insulation material with superior comprehensive properties. The effects of rock wool fiber contents and heat treatment on the properties of the material were investigated. The results show that the addition of rock wool fiber enhances the mechanical properties and heat treatment improves the thermal insulation performance. This material has a simple manufacturing process, eco-friendly properties, and exhibits lightweight construction, high strength, and low thermal conductivity, making it highly suitable for building energy conservation.

Summary: Understanding the impact of cash crop expansion on natural forests is crucial. However, the lack of globally available maps for most crops makes it challenging to estimate the deforestation impacts accurately. In this study, we used Earth observation satellite data and cloud computing to create high-resolution maps of rubber and the associated deforestation in Southeast Asia. Our findings reveal that the deforestation caused by rubber cultivation is significantly higher than previously estimated. With millions of hectares of forest loss and significant rubber plantations in key biodiversity areas, the implications for biodiversity and ecosystem services in Southeast Asia are substantial. Therefore, rubber cultivation deserves more attention in domestic policies, trade agreements, and due-diligence legislation.

Summary: The aim of this study was to investigate the effect of molten spherical basalt particles on the structure formation of cement materials. The results showed that these particles can effectively be used as a mineral additive in cement concretes, leading to an increase in compressive strength. The maximum effect was achieved when 5-10% of finely ground basalt balls were introduced into the mixture. The increased water-holding capacity of the binder created conditions for the consistent growth of hydration products with minimal internal stresses and volumetric deformations.

Summary: This study reveals the characteristics and process of water-rock interactions of natural mineral water in the Changbai Mountain area, China, using hydrochemical and isotopic data. The results show that rock weathering plays a leading role in the chemical composition of mineral water, which is controlled by the lithology and tectonic environment of the region. Feldspar, pyroxene, and olivine are the main factors influencing the mineral water chemistry. The results also suggest a certain delay in precipitation recharge and its significant impact on surface water resources.

Summary: This article focuses on the development of low-carbon alkali-activated binders using cupola dust, showing that proper screening and mechanical activation can lead to excellent bending and compressive strength. Treatment at 90 degrees Celsius for 12 hours accelerates the curing process to 80-90% of natural conditions. The porosity of the samples after heating was found to be 24-25%.

Summary: The presentations in this session of the Monticello II conference aimed to summarize the current knowledge on asbestiform and non-asbestiform elongate mineral particles (EMPs) and the risks of mesothelioma. Case reports of mesothelioma were discussed, along with the weak or lacking evidence on non-asbestiform EMPs and the importance of establishing mesothelioma registries. The session also covered the National Mesothelioma Virtual Bank, the consensus on the potential of long, durable asbestiform EMPs to cause mesothelioma, and experimental studies on engineered nanomaterials.
