In general, injecting grouts into small fractures, cavities, porous soil media, areas of water leakage, fixing cracks or defects in concrete, and filling spaces beneath metal bases digging anchors are widely applied because the great strength workability cement these materials. Furthermore, grout is employed effectively manufacturing semi-flexible pavement mixes. The goal this research to devel...

Some specimens reproducing three leaf stone masonry walls frequently used in Italy, have been built at DIS, Milan, using two different types of stones and tested under compression and shear, up to failure. Subsequently the damaged wallettes were repaired by injection and the effectiveness of the injection was controlled by several NDT (non destructive techniques)

A new type of grouting material—FCM (fast cementing material)—is being used in coastal and offshore infrastructure projects, such as harbor tunnel rehabilitation. In order to investigate how this material performs under different conditions, the compressive strength, failure mode, surface microscopic changes fracture penetration degrees crack angles grout-reinforced specimens formed by FCM sand...

Grout is a binding agent or binder often used with building materials to improve their durability functions. It may be organic or inorganic material used for sealing or consolidation of cracks, pores, or voids in order to improve the mechanical properties and impermeability of a particular system, whether soil, cementitious or of other building materials. Grouts act as dispersion agents where d...

Common approaches to the simulation of Borehole Heat Exchangers (BHEs) assume heat transfer in circulating fluid and grout to be in a quasi-steady state and ignore fluctuations in fluid temperature due to transport of the fluid around the loop. However, in domestic ground source heat pump systems, the heat pump and circulating pumps switch on and off during a given hour; therefore the effect of...
