摘要：

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.
