Title:
SURFACE MODIFYING AGENT FOR MORTAR OR CONCRETE AND SURFACE MODIFICATION METHOD
Document Type and Number:
Japanese Patent JP2009208984
Kind Code:
A
Abstract:

To provide a surface modifying agent which has high permeation property to mortar or concrete using alumina cement and improves the strength of the fragile surface layer formed by dry out or the like, and further which reduces dry shrinkage and neutralization and improves acid resistance, and to provide a surface modification method using the same.

The surface modifying agent, obtained by mixing lithium nitrite and a resin, is applied onto the surface of concrete. Thereby, the lithium nitrite is ionized, deeply permeates into the concrete, and accelerates a reaction. The resin remains at the surface and forms a film so as to prevent the evaporation of water from the inside and to enhance the permeation property and the reactivity. Accordingly, the concrete is protected.
