Influence of the surface treatment of tire rubber residues added in mortars
(Revista IBRACON de Estruturas e Materiais, 2008-06-01) [Artigo]
In this work it was evaluated the influence tire rubber addition in mortars in order to replace part of the sand (12% by volume). It was also intended to verify if the tire rubber treatment with NaOH saturated aqueous ...
Estudo dos efeitos do LiNO3 na reação Álcali-Sílica e comparação com os efeitos da cinza volante na reação
(Revista IBRACON de Estruturas e Materiais, 2010-09-01) [Artigo]
Lithium-based additives have shown satisfactory results in the expansion reduction due to alkali-silica reaction (ASR), but many doubts remain about the mechanisms of ASR. The study herein assessed the effects of a lithium ...
New geopolymeric binder based on fluid catalytic cracking catalyst residue (FCC)
(Materials Letters, 2012-08-01) [Artigo]
This paper provides information about the synthesis and mechanical properties of geopolymers based on fluid catalytic cracking catalyst residue (FCC). FCC was alkali activated with solutions containing different SiO2/Na2O ...
Impact strength and abrasion resistance of high strength concrete with rice husk ash and rubber tires
(Revista IBRACON de Estruturas e Materiais, 2013-10-01) [Artigo]
The paper discusses the application of High Strength Concrete (HSC) technology for concrete production with the incorporation of Rice Husk Ash (RHA) residues by replacing a bulk of the material caking and rubber tires with ...
Variables Involved in the Planting of Rice in the Rice Husk
(Novel and Non-conventional Materials and Technologies For Sustainability, 2012-01-01) [Trabalho apresentado em evento]
Rice production in Brazil in 2010 was approximately 12,2 million tons, and to reach that amount several planting techniques were used with different strains of rice in different rice-growing areas. Since Rice Husk Ash (RHA) ...
Alkali activated materials based on fluid catalytic cracking catalyst residue (FCC): Influence of SiO2/Na2O and H 2O/FCC ratio on mechanical strength and microstructure
(Fuel, 2013-03-29) [Artigo]
Reuse of industrial and agricultural wastes as supplementary cementitious materials (SCMs) in concrete and mortar productions contribute to sustainable development. In this context, fluid catalytic cracking catalyst residue ...
