Influência das variáveis envolvidas no plantio de arroz nas características da cinza de casca de arroz
(Associação Nacional de Tecnologia do Ambiente Construído - ANTAC, 2021-01-08)
Rice production in Brazil in 2008 was approximately 12 million tons, and to achieve that amount several planting techniques were used with different strains of rice in different rice-growing areas. Since Rice Husk Ash (RHA) ...
Polyurethane foams based on modified tung oil and reinforced with rice husk ash I: Synthesis and physical chemical characterization
(Elsevier, 2013-01-17)
A chemically modified tung oil was used as the main polyol component in the formulation of viscoelastic (low resilience) polyurethane foams. Rice Husk Ash (RHA), a residue from the rice process industry, was chosen to be ...

Influence of exposure conditions on the values of strength and absorption in the soil stabilized with lime and rice husk ash
(2013-05-01)
The article presents a study on the influence of exposure conditions on strength and absorption in soil stabilized with lime and rice husk ash. A soil classified as A-4 and CL, known as Red-Yellow Podzol, a hydrated lime ...
Ni mesostructured catalysts obtained from rice husk ashes by microwave-Assisted synthesis for CO2methanation
(Elsevier, 2020-12)
In this work, rice husk ashes were used to obtain a high purity silica precursor to synthesize mesoporous silica frameworks. A novel route for the synthesis of mesocellular silica foam (MCF) was developed using microwave ...
The potencial influence of rice husk ash in self compacting mortar: Cases of mechanical strength and water absorptionA influência potencial das cinzas de casca de arroz em argamassas auto adensáveis: Casos da resistência mecânica e da absorção d’água
(2018-01-01)
The study presents an experiment on the use of rice husk ash (R.H.A) for the production of self-compacting mortars. For this purpose, CPZ II 32 cement, natural sand, industrialized rice hull ash, electrostatic and steric ...
