This study investigates the progressions in mechanical properties of concrete by substitution cement Rice Husk Ash (RHA) conjunction with superplasticizers. husk is a by-product rice milling process, inexact generation 200 kg for every one ton rice. Diffusion matrix enhance concrete. investigation has been done to determine strength parameters various extents supplemented Ash. M20 grade (Design...

In this work, the thermal behavior of rice husk, sewage sludge, and their blends during combustion processes was investigated by means of thermogravimetric analysis (TGA), and the slagging characteristics were studied through X-ray fluorescence (XRF) and melting temperature. The effects of the proportion of rice husk and sewage sludge blends on the combustion process, ignition and burnout chara...

The use of pervious concrete has been significantly considered in recent years. This consideration is due to the properties of pervious concrete in relating to the environmental sustainability that is utilized in the effective management of the runoff from rainfall. Coal extraction and rice husk obtained from milling, produces wastes that have no application and followed by environmental pollut...

Equilibrium moisture content (EMC)/equilibrium relative humidity (ERH) studies pertaining to rice and rice products were reviewed. Methods of determining rice and rice component EMC/ERH data varied, using procedures involving static and dynamic equilibration methods, as well as direct gravimetric methods and indirect ERH‐measurement methods. Methods for measuring rice and rice component moistur...

This study conducted an extensive literature review on rice husk ash (RHA), with a focus its particle properties and their effects the fresh, mechanical, durability of concrete when used as partial cement replacement. The pozzolanic property RHA is determined by amorphous silica content, specific surface area, fineness, which can be improved using controlled combustion grinding for use in concr...

Weedy rice is a close relative of domesticated rice (Oryza sativa) that competes aggressively with the crop and limits rice productivity worldwide. Most genetic studies of weedy rice have focused on populations in regions where no reproductively compatible wild Oryza species occur (North America, Europe and northern Asia). Here, we examined the population genetics of weedy rice in Malaysia, whe...

The present study describes the adsorption of textile dye on rice hull. The adsorption parameters were obtained from Langmuir and Freundlich isotherms utilizing linear regression plots to fit the data. The results showed that Langmuir equation was more suitable than the Freundlich one to predict the experimental adsorption isotherms, indicating that the adsorption of dye molecules is localized ...
