148 Pore reducing technology for concrete US11452516 2006-06-14 US20080163797A1 2008-07-10 Paul W. Brown
The present invention provides methods and compounds for reducing porosity in concrete using alkoxides. In a preferred embodiment, an Si-containing alkoxide, e.g., Si(OC2H5)4 (TEOS) or Si(OCH3)4, may be introduced to concrete where it penetrates the pore spaces.

In addition, hydrous silica formed during the polymerization step may react with calcium hydroxide to form CSH, which may also reduce the volume of pore spaces. The calcium hydroxide may be locally available or it may be provided by introducing a Ca-containing alkoxide solution, which forms calcium hydroxide through a hydrolysis reaction.
