Abstract
The present disclosure relates to a composition that increases the hardness of concrete surface and methods for producing and using the same. In particular, the composition of the disclosure is a solution comprising a solvent and calcium compound, wherein the solvent comprises a polyhydroxy compound, water, and optionally ethanol.
Claims20
A solution comprising a solvent and calcium hydroxide, wherein said solvent comprises a polyhydroxy compound and water, and wherein an amount of water in said solvent is about 80% vol/vol or less.
A method for treating a concrete surface, said method comprising:
- applying a surface hardening composition to a concrete surface which is no wetter than surface-saturated-dry (SSD) condition to produce a first treated surface, wherein said surface hardening composition comprise:
- a solution comprising calcium hydroxide and a solvent comprising a polyhydroxy compound and water;
- and
- applying a silicate densifier to the first treated surface to produce a hardened concrete surface.
An abrasion resistant composition for increasing an abrasion resistance of a concrete surface, said abrasion resistant composition comprising a solution of:
- from about 0.1% wt/vol to about 5% wt/vol of calcium hydroxide;
- and
- a solvent comprising:
- from at least about 10% volume/volume (v/v) to about 50% v/v of a polyhydroxy compound;
- and
- water.
