 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effect of Cement Replacement by Rice Husk Ash on Soft Soil Stabilization) ผู้เขียน: Naphol Yoobanpot, Pitthaya Jamsawang สื่อสิ่งพิมพ์:pdf AbstractThe characteristics of soft soil improvement using cement and rice husk ash were studied. Compressive strength testing of stabilized soil was investigated with various curing times of 3, 7, 14 and 28 d. The correlation between strength development and reaction products was investigated using X-ray diffraction analysis after the strength tests and changes in the stabilized soil structure were investigated using scanning electron microscopy. The results revealed that the soil strength increased when the soil was stabilized with cement and partial replacement of cement with rice husk ash. The results indicated that 30% rice husk ash was the appropriate content for partial cement replacement to produce a stabilized soil strength of 424, 722, 915 and 1,126 kPa at 3, 7, 14 and 28 d curing, respectively. It was also found that the increase in the strength of the stabilized soil was relative to the formation of major reaction products such as calcium silicate hydrate. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Stabilization of Soft Clay Using Waste-Based Cement) ผู้เขียน: ดร.ศุภกิจ นนทนานันท์, รองศาสตราจารย์ , Naphol Yoobanpot สื่อสิ่งพิมพ์:pdf AbstractThis research focused on the potential utilization of waste-based cement (WBC) as a stabilizer to improve the compressive strength of soft clay and also aimed to verify the hardening effects of WBC compared to ordinary Portland cement (OPC). Evaluation of hardening effects was performed based on the compressive strength test and by means of physicochemical tests. The experimental results revealed that the unconfi ned compressive strengths of soil mixes can be improved by stabilizing with WBC to a similar extent to that achieved using OPC. The improvement in strength was due to the enhancement of hydration producing calcium silicate hydrate and calcium aluminate hydrate. |
