In collaboration with UBCeram Group Hudson Resources Inc is assessing the potential of its anorthositedeposit to be used as a cementitious material with refractory properties, Chemically Bonded AnorthositeCements. These structural cements could be produced with nearly zero-CO2 emissions associated with itsproduction and exhibit chemical resistance to acidic and sulphate solutions. These potential properties andadvantages of the novel cements will be thoroughly studied, verified and tested in simulated field conditions.The research will focus on control of processing of the cements in order to achieve the desirable properties, andto control the kinetics of the chemical bonding reactions. The resulting ceramic monolith set cements targetmechanical properties comparable with Ordinary Portland Cement (OPC) and significant structural integritywhen exposed to temperatures in excess of 1400°C.

哈德逊资源公司与UBCeram集团合作，正在评估其斜长石矿床用作具有耐火性能的胶凝材料的潜力，即化学结合的斜长石水泥。这些结构水泥可以在生产过程中几乎零二氧化碳排放的情况下生产，并表现出对酸性和硫酸盐溶液的耐化学性。这些新型水泥的潜在性能和优势将在模拟现场条件下进行深入的研究、验证和测试。研究的重点将是控制水泥的加工过程，以获得所需的性能，并控制化学键反应的动力学。在超过1400°C的温度下，陶瓷整体固化水泥的目标是与普通波特兰水泥(OPC)相当的机械性能和显著的结构完整性。
