grout

[grau̇t]
(materials)
A fluid mixture of cement and water, or a mixture of cement, sand, and water.
Waste material of all sizes obtained in quarrying stone.

Grout

Mortar containing a considerable amount of water so that it has the consistency of a viscous liquid, permitting it to be poured or pumped into joints, spaces, and cracks within masonry walls and floors.

Grout

A binding or structural agent used in construction and engineering applications. Grout is typically a mixture of hydraulic cement and water, with or without fine aggregate; however, chemical grouts are also produced. See Cement

The type most commonly specified in construction and engineering is cementitious grout, which is used where its more conventional sister material, concrete, is less suited because of placing limitations or restrictions on coarse-aggregate contents. Cementitious grouts are used to fill voids and cracks in pavements, building and dam foundations, and brick and concrete masonry wall assemblies; to construct floor toppings or provide flooring underlayment; to place ceramic tile; and to bind preplaced-aggregate concrete. See Concrete

Grout can be formulated from a variety of cements and minerals and proportioned for specific applications. Neat cement grout refers to formulations without aggregate, containing only hydraulic cement, water, and possibly admixtures. Sanded grout is any mix containing fine aggregate and it is formulated much like masonry mortar. Whether neat or sanded, cementitious grouts derive their strength and other properties from the same calcium silicate-based binding chemistry as concrete.

grout

1. Mortar containing a considerable amount of water so that it has the consistency of a viscous liquid, permitting it to be poured or pumped into joints, spaces, and cracks within masonry walls and floors, between pieces of ceramic clay, slate, and floor tile, and into the joints between preformed roof deck units.
2. In foundation work, mixtures of cement, cement-sand, clay, or chemicals; used to fill voids in granular soils, usually by a process of successive injection through drilled holes.

Figures 9 and 10 show the features of slurry veins and bulbs of grouted soils with cement slurry and cement-sodium silicate slurry under initial pressure of 150 kPa, respectively.
It can be seen that all interpretation methods illustrate that the pile capacity of base and shaft grouted pile is greater than that of the base grouted pile and that the capacity of piles with grouting technology is better than that of the traditionally treated pile.
The rock mass after grouting can still be divided into two parts: the grouted rock and the nongrouted fissure.
This type of remedial work is not uncommon in the oil and gas sector, and is a result of the cost/benefit analysis of one installation method over another: welded versus grouted pile/leg connections.
Improperly installed or grouted base plates can compromise equipment reliability and cause future costly maintenance and more downtime.
The results of the project suggest that: * Grouted bolts show more signs of corrosion than ungrouted bolts.
Another of the advantages of chemical grouting is that the material used can be varied in composition to match the specific requirements of the pipes being grouted. For example, since inspections of DGSD pipe had shown significant root intrusion, after the pipes had been cleaned and roots cut, a chemical growth inhibitor was added to the grout to curtail future root intrusion.
When a joint fails the air test, it is grouted. From his control room, the operator controls the injection of chemicals into the void created by the packer.
[13] numerically studied the variation in the mechanical behaviours of fractured rock before and after grouting, considering the heterogeneity of the components in the grouted specimen (e.g., rock particles, grout properties, and some random microcracks within the rock).
Then, starting along one side of the grouted area, position the sponge so that the corner of one long side of the sponge is in contact with the wall and drag the sponge in a continuous stroke up the wall.
One study, conducted by Oregon State University for Salem, Oregon, has concluded that the life expectancy for grouted joints in Salem is 15.6 years.
Osborn says it will also be grouted; "We're looking at our options," he says, "But it's in generally good condition, for 100-year old pipe, and we feel grouting will work well."
