Example text

Some sands, particularly in subtropical areas, are weakly cemented. In some cases that the authors have experienced, the cementation apparently took place while the sand was in a very loose state. The effective pore size in situ may be significantly larger than that indicated by grain size. The ASTM sampling procedures disaggregate the structure, or the friable surviving fragments may be deliberately disaggregated in the laboratory before sieving. On a project in the Middle East where K turned out to be much higher than estimated from grain size curves, a sample was recovered from the excavation with the structure of the weakly cemented sand carefully preserved.

11 LIMESTONE AND CORAL Limestone presents such special problems to dewatering that it demands a separate discussion. Its principal constituent is calcite (calcium carbonate), a mineral that in geologic terms is soluble in water. In its various forms, limestone is abundant in nature; it occurs in massive beds, thin layers, and delicate coral skeletons; it is the hardness in water and the cementing agent in many sandstones. The common mechanism for limestone deposition begins with shellfish. Over geologic ages, the shells accumulate and gradually dissolve until the water becomes supersaturated with calcium carbonate, which then precipitates out to form the limestone.

Dolomite, a rock containing magnesium as well as calcium carbonate, is more resistant to solution action than limestone but still susceptible to the same process. In massive limestone beds, the solutionization tends to be concentrated in the upper zones. Weathered limestone 18 THEORY can be a source of recharge to the soil above. Sometimes a cavern forms and then collapses, causing a sinkhole in the overlying soil at the surface. However, badly solutionized limestone has also been encountered at considerable depth.
