(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.

GROUTED CLAMPS Another form of remedial work is the grouted clamp.
The grouted repair clamp allows for greater design and fabrication tolerances, as the grout fills the annulus and evenly distributes the load of the object the clamp is being placed around.
FoundOcean grouted the annulus between the sleeve and the pipeline, and then installed a grout bag under the pipeline to fill the resulting void and support the additional weight now being carried.
MEMBER FILLING As an alternative, or in addition to grouted clamps, jacket members can be filled with grout to give extra protection from vessel collisions, or to strengthen the structure to extend its design life.
The procedure used was to seal the joint or lateral being tested and grouted using inflatable socks that isolated it from the main sewer flow.
After each joint and lateral was grouted, it was retested and inspected to confirm that it was not leaking.
It was agreed by all parties that these pipes would be removed from the project and bid as a separate project in which they would be rehabilitated with CIPP rather than grouted.
The specific objectives are: (1) to evaluate the working, mechanical and durability of grouts and grouted soils; (2) to characterize the grout-substrate interaction and durability; and (3) to verify the performance of grouted joints and repaired concrete cracks under dry and hydrostatic pressure (241 kPa (35 psi) up to 5 psi in 10 feet of water) using model tests over a period of one month.
Several additional tests were performed with grouted soil and grout-substrate interaction.

Several samples of the grouted contact zone were retrieved which provided further indication that the contact zone had been successfully grouted.
