Dam foundations are generally affected by water leakage and seepage, posing a significant threat to the structure's safety. Such an artificial reservoir unconditionally assumes watertight foundation, as perfect possible, ensure its stability. This brings us back thinking about adequate treatment of foundation through injections grout curtain, which ensures watertightness ground good drainage sy...

In bridges, external post-tension habitually comes as cables placed in ducts for which the residual internal space is (imperfectly) filled with a fluid cement grout. Detecting the problems of injection is not practicable visually from the outside, and no effective auscultation tools were found yet. A recent laboratory experiment established that capacitance probes can be employed, but the main ...

Poor fire resistance of fibre-reinforced polymer (FRP) restricts its further application in construction structures. In this paper, a novel fibre-reinforced cementitious matrix confined concrete column (FRCMCC) using fireproof grout as the fibre matrix was developed, and experiments were conducted to establish its performance and analyse the mechanical properties under axial compression. The te...

Electro-osmosis in clayey soils and sediments, for purposes of clay consolidation, dewatering, or cleanup, and electro injection in porous media is widespread recent decades. It is experimentally found that the chemical properties of porous media especially PH change the characteristics of media. Electro-osmotic conductivity is a function of soil and grout material chemistry, altering with time...

In general, it is neither (a) determinative on these matters, typically simply proposing different options for addressing them, nor (b) complete in its discussion of the significant number of complex conceptual and measurement issues (some of which are outlined in the attached note from Professor Grout) raised by a proposal to undertake analysis of this nature. In these circumstances, it is our...

a new type of infilled frame has been recently proposed. it has a frictional sliding fuse, horizontally installed at the mid-height of the infill. it has already shown that such infilled frames have higher ductility, strength and damping ratio as well as more enhanced hysteresis cycles, compared with regular infilled frames. this experimental paper is focused on the influence of gravitational l...
