    “…Palm olein exhibits a refining effect on intrinsic pores formed by geopolymerization. In addition, using appropriate amounts of palm olein and H(2)O(2), geopolymer foams can achieve higher open porosity and better pore connectivity, resulting in the improvement of water absorption and thermal insulation capacity.…”

    “…A H(2)O/Na(2)O ratio of 9~10 yields the highest strength and the fastest final set simultaneously, due to the maximized degree of geopolymerization. Moreover, the accompanying sensitivity analysis indicates that the workability depends chiefly upon the H(2)O/Na(2)O ratio, the final setting time on the SiO(2)/Al(2)O(3) ratio and, that the compressive strength relies on both of them. …”
