测试各种不同黏土在挤出土坯砖生产中的适用性。12个黏土中选择3个,做满足现代质量标准要求的土坯砖建筑物的相关测试。将各种传统的和现代的外加剂以不同比例掺加入壤质黏土,改性后的黏土经挤出成型后,经受耐久性试验。发现大部分外加剂提高了干抗拉强度且避免性能转移。本项目研究中的发现详列于本稿。 Test the suitability of different types of clay in the production of extruded Adobe brick. Three out of 12 clay samples were tested to meet the requirements of modern quality standards for adobe brick buildings. A variety of traditional and modern additives in different proportions into the loamy clay, the modified clay after extrusion, to withstand durability test. Most admixtures were found to increase dry tensile strength and avoid performance transfer. The findings of this project study are detailed in this draft.
