Cement is a representative material in construction projects because it is a blinder that is characterized as a rigid material and provides compressive strength. Cement production is one of the major pollutants, taking into account the CO2 emissions generated by the use of rotary kilns that must be a temperature higher than 1400oC for the calcination of limestone. This research arises from the need to find a material that can replace or reduce the use of cement and reduce pollution to the environment. In this way this research seks the timely dosage of a mortar with quicklime and slaked lime with which a competitive compressive strength for cement can be obtained, in this document the tests that were necessary to perform the dosage will be presented, taking into account the Colombian Technical Standard, NTC 110 establishes the method for determining the normal consistency of lime, NTC 118 establishes the test method for determining the setting time of lime, NTC 111 establishes the method for determining the flow of mortars and NTC 220 establishes the method for determining the resistance of mortars.
