Provided are compositions and methods of using a liquid suspension of hollow particles comprising a plurality of hollow particles, water, a suspending aid, and a stabilizer selected from the group consisting of a non-ionic surfactant, a latex, an oleaginous fluid, porous silica, and combinations thereof. The liquid suspension is homogenous. An example method includes statically storing the liquid suspension in a container for at least one week; wherein the liquid suspension maintains a difference in density from the top of the container to the bottom of the container of less than one pound per gallon while stored. The method further includes adding the liquid suspension to a treatment fluid; wherein the liquid suspension reduces the density of the treatment fluid; and introducing the treatment fluid into a wellbore penetrating a subterranean formation.

The present invention relates to an asphalt slurry seal composition comprising a mineral filler comprising an inorganic mineral blend having a multi-modal particle size distribution comprising at least a first maximum in the range of about 0.1 μm to about 15 μm and a second maximum in the range about 5 μm to about 35 μm, wherein about 5 wt. % to about 40 wt. % of the particles in the inorganic mineral blend (dry weight) are in the range of about 0.1 μm to about 15 μm, a pigment component comprised of at least one pigment, an additive component comprising at least one rheology modifier, an asphalt emulsion, optionally one or more functional minerals, and water. Further, the particles of the inorganic mineral blend may be subjected to surface treatments.

The present invention provides for a compressible grout mix for filling an annular gap between a tunnel rock wall surface and a tunnel liner of a tunnel in a rock formation subject to time dependent deformation after excavation and a method of filling the annular gap between a tunnel rock wall surface and a tunnel liner of a tunnel in a rock formation subject to time dependent deformation after excavation utilizing the compressible grout mix for resilient absorption of forces in the hardened state of the compressible grout mix exerted by the time dependent deformation of the rock wall surface into the tunnel opening. The method includes:

a. providing the compressible grout mix comprising hydraulic binding agent, bentonite clay, polymer foam particles, water-reducing admixture, water and air,

b. placing the compressible grout mix in the annular gap between the tunnel wall rock surface and the tunnel liner, and

c. allowing the compressible grout mix to set, wherein the compressible grout mix in the hardened state has a compressible ratio greater than the anticipated time dependent deformation.
