Paper Cement for Plant Pot Casting

Abstract

Paper cement in plant pot casting, an integral component of cement sand and wastepaper, has been considered as an environmentally friendly material due to the presence of the waste content. In this study, the appropriate paper cement formula for plant pot construction was randomly designed throughout the triangular table methodology. In brief, the amount of the paper cement composition was specified according to the limiting interval of 20 - 80% cement, 10 - 70% sand and another 10 – 70% of wastepaper. The derived ten cement paper formulas were then subsequently subjected two treatments with different conditions, 7 and 28 days air-exposure incubation. The results revealed that the value of water adsorption was 13.36-45.91% and 16.42-109.86%, the scores of compression tests were at 12.27-94.99 and 3.14-95.45 kg/cm², respectively, whereas the physical property average score was at 3.75-4.50 points. Therefore, the three paper cement formulas : no. 1, 2 and 3 were proved to yield suitable materials for paper cement plant pot construction.
