Curable compositions

A grout composition comprising:

• (A) 0.1-10 wt. % of an alkoxysilyl-terminated, urethane-group-containing polymer component of the formula:
• Y—[(CR12)b—SiRa(OR2)3-a]x (I),
• wherein
• Y is an x-valent polymer radical bonded via nitrogen, oxygen, sulfur, or carbon,
• R is identical or different monovalent, optionally substituted, SiC-bonded hydrocarbon radical,
• R1 is identical or different, and is a hydrogen or a monovalent, optionally substituted hydrocarbon radical, optionally bonded to carbon via nitrogen, phosphorus, oxygen, sulfur, or carbonyl group,
• R2 is identical or different, and is a hydrogen or a monovalent, optionally substituted hydrocarbon radical,
• x is an integer from 1 to 10,
• a is identical or different and is 0, 1, or 2,
• b is identical or different and is an integer from 1 to 10;
• (B) 0.1-30 wt. % of a silicone resin component comprising units of the formula
• R3c(R4O)dSiO(4-c-d)/2 (II),
• wherein
• R3 is identical or different, and is a hydrogen or a monovalent, SiC-bonded, optionally substituted hydrocarbon radical,
• R4 is identical or different, and is a hydrogen or a monovalent, optionally substituted hydrocarbon radical,
• c is 0, 1, 2, or 3, and
• d is 0, 1, 2, or 3,
• wherein the sum of c+d≤3 and in at least 50% of the units of the formula (II) c=0 or 1;
• (C) 0.1-5 wt. % of surfactant(s);
• (D) 50-95 wt. % of aggregate;
• and optionally:
• (E) 0-5 wt. % of alkoxy silane(s);
• (F) 0-5 wt. % of catalyst(s);
• (G) 0-5 wt. % of additives;
• (H) 0-5 wt. % of adhesion promoters;
• and
• (I) 0-5 wt. % of water scavengers,
• wherein the grout composition is a storage stable water-free grout composition.
