| Abstract | Slaking and swelling behavior of' siltstones of Lam Ta Khong Pumped Storage Project were investigated. Slaking can occur by wetting. nut its intensity depended on the initial moisture conditions and the manner the rock absorbed moisture. Air-dried samples slaked badly when immersed in water. But. it did not slake much when slowly absorbing moisture in humid room. Near saturated sample did not slake when immersed in water. Slaking intensity in wetting test increased with a decrease in degree of saturation. The siltstones did not contain expansive clay minerals as indicated by the free swell values and other index properties. nut the result of swell-consolidation (SC) tests of air-dried samples showed very high values (0.56-14.86%) of swelling strains and pressures (2.6-16 MPa). While some consolidation-swell (CS) test showed a much lower values. This was due to effect of slaking of the samples in SC tests when water was added at very low axial pressure. |
