Improvement of frost durability of vinylon fiber reinforced cement board
In order to improve the frost durability of the vinylon fiber reinforced cement board (FRCB), surface-carbonation of the board was studied to control the pore structure near the surface. The pore size distribution of each sample was measured using a mercury injection instrument in the range of diameters of from 10-2 to 15 micrometer. The carbonation precipitated fine crystalline calcite on the surface of the FRCB and reduced the water absorption by decreasing fine pores from about 0.02 to 0.8 micrometer in diameter. Thus, it was experimentally confirmed that the frost durability of the FRCB was effectively enhanced by surface carbonation.
