Abstract
New construction materials were developed and patented in Brazil, based on concrete production and demolition wastes mixed with lime production waste. The main objective of this research is to utilize these two types of industrial wastes on as large a scale as possible as a new raw materials for the production of concrete. The lime waste is characterized by a high content of Si[O.sub.2], [Al.sub.2][O.sub.2], CaC[O.sub.3] and other elements. After 90 days of aging in open air, the water absorption value of the sample mixtures was 12% and the uniaxial compression strength reached up to 33 MPa, with an average of 29 MPa. XRD and SEM analyses of the ...
