งานวิจัยนี้ศึกษากำลังอัดและโครงสร้างทางจุลภาคของจีโอพอลิเมอร์ที่ได้จากเถ้าถ่านหินและซิลิกาที่สกัดจากเถ้าแกลบซึ่งเถ้าแกลบถูกนำมาสกัดซิลิกาโดยการใช้กรดไฮโดรคลอริค (HCl) และแปรเปลี่ยนค่าอุณหภูมิการเผาแกลบในช่วง 100–800 องศาเซลเซียส นำเถ้าแกลบผสมเถ้าถ่านหินในอัตราส่วน 10 : 90 โดยน้ำหนัก และใช้สารละลายโซเดียมไฮดรอกไซด์ความเข้มข้น14 โมลาร์ ผสมจีโอพอลิเมอร์แบ่งเป็น 2 ลักษณะ คือ ลักษณะที่ 1 นำซิลิกาที่สกัดจากเถ้าแกลบผสมกับเถ้าถ่านหิน แล้วผสมกับสารละลายโซเดียมไฮดรอกไซด์ และลักษณะที่ 2 นำซิลิกาที่สกัดจากเถ้าแกลบผสมกับสารละลายโซเดียมไฮดรอกไซด์แล้วผสมกับเถ้าถ่านหิน ทดสอบกำลังอัดของวัสดุ ศึกษาโครงสร้างทางจุลภาคด้วยเทคนิค SEM และ XRD การศึกษาพบว่า จีโอพอลิเมอร์เพสต์จากเถ้าแกลบที่เผาที่อุณหภูมิ 200 องศาเซลเซียส ให้ค่ากำลังอัดสูงที่สุด วิธีผสมลักษณะที่ 1 ให้กำลังอัดที่สูงกว่าวิธีผสมลักษณะที่ 2 เนื่องจากมีค่าความเป็นด่างมากพอที่ชะซิลิกาและอะลูมินาจากวัสดุตั้งต้นเพื่อทำปฏิกิริยาจีโอพอลิเมอร์ไรเซชัน ลักษณะโครงสร้างทางจุลภาคเกิดสารประกอบใหม่ที่เกิดการจากทำปฏิกิริยาของเถ้าถ่านหินและซิลิกาที่สกัดจากเถ้าแกลบ
