RESUMO:

The use of construction and demolition waste (C&DW) has become more relevant, especially due to economic and environmental matters. The current trend in developed economies is to treat the C&DW as a potential resource for many purposes, including as aggregates for concrete. Its use as aggregate, however, can worsen the concrete’s properties. Some of the alternatives capable of reducing the negative impact of C&DW in concrete are the use of modified concrete mixing methods, and the addition of pozzolans. The purpose of this research is to measure and analyze the improvement to the mechanical, rheological and morphological properties of concretes made with C&DW as coarse aggregates, by variating pozzolan additions and concrete mixing methods. For this purpose, concretes made by the Triple Mixing Method and the Two Stage Mixing Approach, with different levels of rice husk ash and silica fume additions will be tested. Axial compression, elasticity modulus and water absorption capacity tests will be performed, as the electron microscopy scanning. At the end of the research it is expected to obtain 100% recycled coarse aggregate concretes with mechanical and rheological properties similar to those of concretes made with 100% natural coarse aggregates.
