1. CARBONATAÇÃO NATURAL DE PROTÓTIPOS DE CONCRETO COM CINZA DE CASCA DE ARROZ SEM MOAGEM / NATURAL CARBONATION IN CONCRETE PROTOTYPES WITH NON-GROUND RICE HUSK ASH
Cement is the construction building material with higher responsibility by carbon dioxide emission of all industrial human activities, besides be a considerably expensive material, more than the rice husk ash in nature. Environmental benefits are generated in its utilization, because rice husk ashes are industrial process residues of the grain processing, th

2. CARBONATAÇÃO EM CONCRETO COM CINZA DE CASCA DE ARROZ SEM MOAGEM / CONCRETE CARBONATION WITH UNGROUND RICE HUSK ASH
This research is part of a project that aimed to evaluate the technical viability of the use of unground (in natura) residual Rice Husk Ash (RHA), without grinding, for structural concrete. The present work investigated the evaluation of the depth and the determination of the carbonation coefficients for concrete with the addition of 15% and 25% residual RHA

3. CONCRETE MICROESTRUTURE STUDY WITH ADDITION OF UNGROUND RESIDUAL RICE HUSK ASH WITHOUT BURN CONTROL / ESTUDO DA MICROESTRUTURA DO CONCRETO COM ADIÇÃO DE CINZA DE CASCA DE ARROZ RESIDUAL SEM BENEFICIAMENTO
The use of mineral adition in concrete is a widely studied theme for several researchers that looking for features like: save cement for reducing costs, durability improvement to increase mechanical strenght and use of industrial wastes for reducing environmental pollution. This study intend to analize the microstructure of concretes mixtures with ungrounded

4. Aplicabilidade das cinzas da casca de arroz
Currently, the accumulation of rice husk is a serious environmental problem. The burning of rice husk generates a considerable volume of ash, that falls to the ground and gets into the air and the rivers, causing a disequilibrium in the ecosystem. This motived research into solutions that aim to exploit the husks for energy generation and the ashes for devel
