The use of construction and demolition waste in the industry has been a constant issue for several years due to amount generated as well need reduce consumption natural aggregates. This study aim optimizing recycled aggregate from verify its influence on elastic modulus structural concrete. For this, substitution coarse by was evaluated at replacement percentages 0%, 25%, 50%, 75%, 100% concrete with different water/cement ratios (0.40, 0.50, 0.60). With these criteria, macrostructural tests...
Due to their high tensile strength and toughness, natural fibers have been proposed as reinforcing material in mortars reduce cracking. Coir fiber has excellent potential for reuse cementitious matrices among the various types. However, this is hydrophilic a extractive content, including wax, oils, other components structure. Different chemical treatments are used remove contaminants from surface of coir minimize presence these elements. This study evaluated chemically treated based on...
The use of nanomaterials in concrete has shown promise, and the several types cementitious compounds been found to guarantee greater physical–mechanical properties improvements microstructure. mineral admixtures, such as silica fume, ensures improvement interfacial transition zone (ITZ) between aggregate paste high-performance (HPC). Thus, this work evaluates performance superplasticizer additive with colloidal nanosilica suspension slurried fume HPC its macro- micro-structural properties....

Ao longo dos últimos anos tem sido cada vez mais importante a agenda ambiental para empresas e governos.A construção civil, entretanto, grande impacto tanto nas atividades econômicas quanto no da indústria brasileira.Os materiais base de cimento têm parcela responsabilidade nos impactos visto que são os utilizados carregam consigo emissões CO 2 .A partir disso, presente pesquisa propõe-se investigar o do uso agregados reciclados resíduo demolição (RCD) em sua fina.Com isso, tem-se como...
Faced with already perceptible climate changes, it is increasingly necessary to adopt practices that are more aligned the concepts of sustainable development. Life Cycle Assessment (LCA) a method used globally assess potential environmental impact indicators most diverse products and services throughout their life cycle. In civil construction, specifically, removal raw material, transportation, use phase, demolition, recycling, reuse, etc. It study new materials construction methods, waste...
