摘要
摘要本研究针对纳杰夫地区一种利用当地可利用材料的开挖浆体进行研究。另一方面,主要的做法是在深侧基础特别是桩基础和钻油井进行支撑。检查浆料的7项性能,包括粘度(表观塑性和漏斗沼泽)、屈服应力、密度、酸度和凝胶力(10-0分钟)。分别为11.7367、8.8733、38.1667、11.5467 mPa·s、1.1045 kg m−3、10.9067、11.2683 mPa·s。根据上述性能的测试结果,可以生产出符合美国石油协会规格的产品,并根据标准ACI 336.3R-93:2006的要求,不含添加剂。随着粘土粉浓度的增加,随着剪切力的时间和速度的增加,通常构成这些泥岩结构的坡缕石纤维束被破坏,从而实现了流变行为的改善。
Assessment of excavation slurry produced clayey mineral from the Bahr Al-Najaf region
Abstract This study targeted to investigate a type of excavation slurry by local available material in Najaf region. On the other hand, chief practises is supported the deep sides of foundation in particular pile foundation and, drilling oil wells. The results of slurries are checking, for seven properties, which includes the viscosity (apparent plastic and funnel Marsh), yield stress, density, acidity, and gel power (10–0 min). Which are 11.7367, 8.8733, 38.1667, 11.5467 mPa·s, 1.1045 kg m −3 , 10.9067, and 11.2683 mPa·s, respectively. On the basis of the results tests for the above properties, that is possible to produce a product that conforms to the specifications of American Petroleum Institute specifications, and according to the requirements of the standard ACI 336.3R-93:2006 without additives. The rheological behavior improvement is achieved through the breakdown of the bundles of palygorskite fibers that normally make up the texture of these mudstones by increasing the time and speed of the shear force as soon as increasing the concentration of clay powder.
期刊介绍:
Pollack Periodica is an interdisciplinary, peer-reviewed journal that provides an international forum for the presentation, discussion and dissemination of the latest advances and developments in engineering and informatics. Pollack Periodica invites papers reporting new research and applications from a wide range of discipline, including civil, mechanical, electrical, environmental, earthquake, material and information engineering. The journal aims at reaching a wider audience, not only researchers, but also those likely to be most affected by research results, for example designers, fabricators, specialists, developers, computer scientists managers in academic, governmental and industrial communities.
