Main principles of composite construction of alkaline OPC with high (60...80 %) filling by active mineral compounds of a natural and artificial origin in which the alkaline component is entered both as powder and an alkaline solution were established. Their observance allows to receive binding compositions with setting time 0-42...1-35 h-min and strngth: 2 days -15...20 MPa, 7 days - 22,0...35,6 MPa, 28 days - 38...55 MPa, 90 days - 43.. .. 59 Mpa, 180 days - more than 60-65 MPa, that allows to relate them to rapid-setting cements at the content of clinker component within the 5-40 % by mass.
