Penetrability for Cementitious Injection Grouts

Mass transport properties of mature wasteform grouts

6 Release of gases from intermediate level radioactive wastes encapsulated in cement-based wasteform grouts is a 7 major concern during the interim storage, transportation and operational stage of a phased geological repository 8 system. The ability of the wasteform grout to retain radioactive gases depends on its mass transport properties, 9 which evolve with age, water saturation degree and a...

Corrosion Performance of Prestressing Strands in Contact with Dissimilar Grouts

To improve the corrosion protection provided to prestressing strands, anti-bleed grouts are used to fill voids in post-tensioning ducts that result from bleeding and shrinkage of older portland cement grouts. Environmental differences caused by exposing the strands to dissimilar grouts, however, have the potential to cause rapid corrosion. Portland cement grout, gypsum grout, and four commercia...

Microstructural Effects of Sulphate Attack in Sustainable Grouts for Micropiles

Nowadays, the use of micropiles has undergone a great development. In general, they are made with cement grout, reinforced with steel tubing. In Spain, these grouts are prepared using OPC, although the standards do not forbid the use of other cements, like sustainable ones. Micropiles are in contact with soils and groundwater, in which the presence of sulphates is common. Their deleterious effe...

Adhesive Bonding to Dentin Improved by Polymerizable Cyclodextrin Derivatives

The objective of this work was to determine bonding characteristics of a hydrophilic monomer formulation containing polymerizable cyclodextrin derivatives. The hypothesis was that a formulation containing hydrophilic cross-linking diluent comonomers and cyclodextrins with functional groups attached by hydrolytically stable ether linkages could form strong adhesive bonds to dentin. The previousl...
