Abstract:
The aim of this study was to develop an efficient approach to the processing of cellulose fiber-reinforced cement composites, which makes value-added use of carbon dioxide. Two categories of cellulose fiber cement boards were evaluated: pressed and unpressed. Comparisons were made between the physical and mechanical properties of cellulose fiber cement products fabricated with conventional and CO2 curing using different processing conditions. This paper describes the results of an attempt at the sustainable processing of cementitious composite products—preferably environmentally friendly—that incorporate cellulose fiber. Response surface analyses of experimental results are used to identify optimum curing conditions. Analysis results yielded the preferred processing conditions of cellulose fiber cement boards. In both pressed and unpressed boards, oven temperature and duration have significant effects on the performance of the end product. CO2 curing in some conditions yielded better results when compared with conventional curing, even at half the autoclave duration.
