1. A mortar with embedded steel reinforcement bars, the mortar comprising:
a binder;
a fine aggregate; and
a coupled borate/silicate salts-based additive, the additive comprising:
silicate compounds that include one or more salts selected from the group consisting of sodium, potassium, lithium, calcium, magnesium, manganese, iron, zinc and aluminum; and
borate compounds that include one or more salts selected from the group consisting of sodium, potassium, lithium, calcium, magnesium, manganese, iron, zinc, and aluminum;
wherein steel reinforcement bars are embedded in the mortar; and wherein:
a concentration range of the silicate compounds is from about 0.1% to about 5.0%, with respect to the weight of the binder in the mortar; and
a concentration range for the borate compounds is from about 0.1% to about 5.0%, with respect to the weight of binder.
