The evolution of trapped geothermal heat in hot underground mine along with emission of toxic gases and dust during mine activity makes the mine environment unfavorable is hazardous to worker’s health. This imposes significant demand on cooling and ventilation systems. As a result, substantial costs are incurred while implementing environmental regulation processes to dissipate the heat and provide comfortable working conditions. Thus, as an alternative, the development of cost effective materials to act as efficient thermal insulators is on the rise. Thermal conductivity is an important property that is a direct measure of a material’s ability to facilitate/deter heat flow. In addition to their superior chemical resistance, adequate mechanical strength, abrasion and fire retardant as well as environmental benefits in comparison to existing building materials such as ordinary Portland cement, aluminosilicate based geopolymers are now gaining widespread interest as promising thermally insulating and sustainable materials. This paper begins with an overview of geopolymers, transitioning into a discussion of recent developments in the field of geopolymer development as a thermally insulating material broadly classified into: filled geopolymers and porous geopolymers resulting in structures with enhanced ability to impede heat flow.

基于地质聚合物的隔热材料的最新进展——综述文章

地下高温矿井中滞留地热的演变以及矿井活动过程中有毒气体和粉尘的排放，使矿井环境变得不利，危害工人的健康。这对冷却和通风系统提出了很高的要求。因此，在实施环境监管程序以散发热量并提供舒适的工作条件时，会产生大量成本。因此，作为替代方案，开发具有成本效益的材料以用作有效的热绝缘体正在兴起。热导率是一种重要的特性，它直接衡量材料促进/阻止热流的能力。除了优异的耐化学性、足够的机械强度外，与现有建筑材料（如普通波特兰水泥）相比，具有耐磨性和阻燃性以及环境效益的铝硅酸盐地质聚合物作为有前途的隔热和可持续材料，现在正受到广泛关注。本文首先概述了地质聚合物，然后过渡到讨论作为隔热材料的地质聚合物开发领域的最新发展，该材料大致分为：填充地质聚合物和多孔地质聚合物，从而形成具有增强的阻止热流能力的结构。
