An anti-corrosion agent for use with a cementitious composition which is to be reinforced, comprising one or more species selected from a group consisting of alkyldiamines represented by the general formula RHN-(CH2)n-NH2 (in which R is an alkyl having C8-22 atoms, and n is an integer of 1-5) and alkylamines represented by the general formula R-NH2 (in which R is an alkyl having C8-22 atoms). The agents give good anti-corrosion performance which does not decline with time and exposure to the elements to the same extent as is the case with conventional anti-corrosion agents. |
