Carbonation investigation on atmospherically exposed lime-treated silty soil

The effect of carbonation on a one-year atmospherically exposed lime-treated soil structure is investigated. investigation involves analyzing the chemical characteristics and pore-structure modifications several specimens sampled up to 12 cm depth perpendicular surface. On comparing analysis with untreated core-sampled specimens, found have occurred 4.2 decrease in pH value 9 or lower than that presence carbonates confirmed effect. At level, mechanism increase macropores diameter 20000–100000 Å, which missing non-carbonated even greater one at soil. Such an observation loss cementitious compounds due carbonation, thus, converting mesopores developed lime treatment larger pore diameter.
