STRENGTH AND BEARING CAPACITY OF ARTIFICIALLY CEMENTED SANDS

The strength and bearing capacity of artificially cemented sands were examined by laboratory triaxial and model footing tests. Ordinary Portland cement in the amount of 1% by weight was used as an additive to produce a weakly cemented sand. Drained isotropically consolidated triaxial compression tests, and model strip footing tests were carried out on the cemented sand to determine its strength characteristics c, phi and the ultimate bearing capacity and the failure mode of shallow footings. The results are compared with similar tests on uncemented sand of identical origin and relative density. The results indicated that the angle of friction phi is not affected by cementation. However, a cohesion intercept, c, of 25 kPa is produced by cementation which led to a significant increase in bearing capacity. Cemented sand displayed a stiff response characterized by larger soil modulus and small footing settlement under load. The conventional bearing capacity formula is used for weakly cemented sand for prediction of the bearing capacity. (Author/TRRL)
