BENTONITE-CEMENT AND ITS APPLICATIONS

LA BENTONITA-CEMENTO Y SUS APLICACIONES

Until recently, bentonite has mainly been used in soil injection and grouting and as an auxiliary material in drilling works. The properties of bentonite may be considerably improved by the addition and intimate mixing of a certain amount of cement. The article deals with the new applications of bentonite, cement and water systems. Many properties of this material are given, such as: viscosity, setting time, decantation, density, permeability, erodibility, resistance, plasticity, durability and deformability. The variation of these properties caused by differences in proportioning is also considered. Because of the different properties of the material which can be achieved by varying the proportions, a series of innovative applications is presented. Among these "new" applications the following are put into consideration: impermeable walls (soft or plastic walls, self-hardening slurry trenchwalls and its application in impermeable cores of earth dams or in excavation works, prefabricated walls and mixed walls, semihard footing pieces. The savings and the advantages of these applications as compared with solutions of another type are commented upon. /TRRL/
