The use of kaolinitic clay, which chemical compound consists of mainly silica (SiO2) and alumina (Al2O3), mixing with charred seashells, consisting of mainly calcium oxide (CaO), could be improved by polymerization process. The ratio of kaolinitic clay and charred seashells used in the study ranges from 1: 0.6 to 1: 1.6 by weight. After curing for 28 days, the improved material has the ultimate compressive strength in the range of 3.7 to 7.9 MPa. In additions, the improved material has good heat resistance property. The utilization of natural waste materials together with polymerization technique could improve the material properties to meet the demand of construction industry in the future. |
