Abstract
A composition is provided which comprises a first component, a second component, and a compressible substance in which the first component comprises a peroxide, a liquid which comprises water, and a solid particulate; and the second component comprises a polymer, a crosslinking agent, and a solid particulate. The composition can further comprises a sugar. Also disclosed is a process that can be used for preventing a grouting composition from becoming limp. The process comprises combining a grouting composition with a compressible substance in which the composition comprises a first component and a second component as disclosed above.
Claims26
A grouting composition comprising a first component, a second component, and a compressible substance wherein said first component comprises a peroxide, a liquid which comprises water, and a solid particulate;
- said second component comprises a polymer, a crosslinking agent, and a solid particulate and said liquid is present in said first component in the range of from about 5 to about 35 weight % of said polymer and said first component, second component, or both further comprises sugar.
A grouting composition comprising a first component, a second component, and a compressible substance wherein
- said first component comprises a peroxide, a liquid which comprises water, and a solid particulate;
- said second component comprises a polymer, a crosslinking agent, said liquid, and said solid particulate;
- said compressible substance is selected from the group consisting of nitrogen, oxygen, air, carbon dioxide, foam rubber, carbon dioxide, argon, and combinations of two or more thereof;
- said peroxide is selected from the group consisting of benzoyl peroxide, dichlorobenzoyl peroxide, dibromobenzoyl peroxide, dimethoxy benzoyl peroxide, and combinations of two or more thereof;
- said solid particulate is selected from the group consisting of calcium carbonate, limestone, sand, cement, gypsum, fiber glass, paper fibers, and combinations of two or more thereof;
- and
- said liquid is present in said first compartment in the range of from about 5 to about 35 weight % of said polymer and said first component, second component, or both further comprises sugar.
A process comprising combining a grouting composition with a compressible substance wherein said composition comprises a first component and a second component;
- said first component comprises a peroxide, a liquid which comprises water, and a solid particulate;
- and said second component comprises a polymer and a crosslinking agent.
