Abstract
Abstract A grouting composition for use in contacting the soil whereby the soil will become stabilized. The composition, based on a liter of solution, consists of from 350 to 675 cc of alkali metal silicate having an alkali metal oxide:silicon dioxide ratio of about 1:3 to 1:5 and having a solids content between 30 and 45 weight percent; from about 25 to 200 cc of an amide of the structure WHEREIN R is selected from the group consisting of hydrogen, lower alkyl, -CONH2, and lower alkyl-substituted amide groups, from 5 to 50 cc of an ester which is soluble in said amide; and the balance water.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
86 words
A GROUTING COMPOSITION CONSISTING, PER LITER OF SOLUTION OF FROM 350 TO 675 CC ALKALI METAL SILICATE HAVING AN ALKALI METAL OXIDE:SILICON DIOXIDE RATIO OF ABOUT 1:3 TO 1:5 AND HAVING AN ALKALI METAL SILICATE SOLIDS CONTENT BETWEEN 30 AND 45 PERCENT; FROM ABOUT 25 TO 60 CF FORMAMIDE; FROM 5 TO 50 CC OF ETHYL ACETATE, AND THE BALANCE WATER, SAID ETHYL ACETATE BEING DISSOLVED IN SAID FORMAMIDE AND THE COMBINATION OF THE FORMAMIDE AND ETHYL ACETATE BEING PRESENT AS A SOLUTE IN SAID COMPOSITION.
Claim 2
Dependent Claim
86 words
A GROUTING COMPOSITION CONSISTING, PER LITER OF SOLUTION OF FROM 350 TO 675 CC ALKALI METAL SILICATE HAVING AN ALKALI METAL OXIDE:SILICON DIOXIDE RATIO OF ABOUT 1:3 TO 1:5 AND HAVING AN ALKALI METAL SILICATE SOLIDS CONTENT BETWEEN 30 AND 45 PERCENT; FROM ABOUT 25 TO 60 CF FORMAMIDE; FROM 5 TO 50 CC OF ETHYL ACETATE, AND THE BALANCE WATER, SAID ETHYL ACETATE BEING DISSOLVED IN SAID FORMAMIDE AND THE COMBINATION OF THE FORMAMIDE AND ETHYL ACETATE BEING PRESENT AS A SOLUTE IN SAID COMPOSITION.
Claim 3
Dependent Claim
15 words
A composition in accordance with claim 1 wherein said alkali metal silicate comprises sodium silicate.
Claim 4
Dependent Claim
103 words
A grouting composition consisting, per liter of solution, of from 500 to 675 cc alkali metal silicate having an alkali metal oxide:silicon dioxide ratio of about 1:3 to 1:5 and having an alkali metal silicate solids content between 30 and 45 percent; formamide, ethyl acetate, and the balance water, said ethyl acetate being dissolved in said formamide and the combination of the formamide and ethyl acetate being present as a solute in said composition, said formamide and ethyl acetate each being present in amounts between 25 and 50 cc with the amount of ethyl acetate being approximately equal to the amount of formamide.
