This document contains the results of the work carried out in the period 2019-2020 as part of the research `` URBAN RISK: DIAGNOSTIC APPROACH FOR THE CITY OF MANAGUA '' accredited by the UNI, one of the objectives of the same being the diagnosis of cinder block masonry systems and the proposal of a new material. In this sense, from the waste generated in the laboratory in tests of the masonry system, a proposal for recycled concrete was elaborated from this rubble, grinding and screening these materials to sand granulometry and proposing a dosage mixture based on in similar studies. The proposed tests, based on the procedures of the ASTM standards and national regulations, were the compression test of 15 x 30 cm cylinder specimens and the speed of the ultrasonic pulse, obtaining acceptable and useful results for the elaboration of non-use parts. structural.
