In this study, silica gel was extracted from rice husk ash using a modified acid-leaching process. The gel was then characterized using an X-ray Diffractometer (XRD) and an X-ray Fluorescence (XRF). At different loadings of 0, 0.05 and 0.10 wt.%, sil... see more

Hydroxyapatite (HA) has been deposited on silica (SiO2) particles to produce HA-SiO2 composite that will be used as the powder component of calcium phosphate cement. HA was expected to be on the composite surface to maintain its bioactivity. SiO2 was made... see more

Steam curing is a process used to accelerate cement hydration reactions with the purpose of enhancing the mechanical strength of concrete at early ages, since hydration reactions are temperature dependent. To evaluate the influence of temperature on the d... see more

The use of Portland cement is considered a very good material for making concrete. This is because many are found in building shops and it's high performance in making concrete. Research on alternative Portland cement is a worldwide priority for reducing ... see more

An investigation of characterization of a sandy soil mixture with rice husk ash (RHA) and lime is presented. Their objective was to study the physic and mechanic properties of the mixtures, trying to find an economical solution for low-volume transit pave... see more

We have done the fabrication of two kinds of composite material the fillers that we used rub ash for one type of composite and the husk of rice for another, the matrix for both is resin. The resin - rub ash composite, the volume ratio of filler and matrix... see more

White rice husk ash obtained from complete uncontrolled burning of rice husk contains more than 94% silica. The ash, which consists of crystalline silica of the type tridymite and a-crystobalite, was used directly as a source of silica in the synthesis of... see more

Recently, the increase in demand for rice has led to the numerous availabilities of rice husks (RH) in Malaysia. RH is being utilized as industrial fuel to generate electricity through incineration process in the boiler. During the incineration process, r... see more

Stabilizing elemental mercury using elemental sulfur has been a laboratory standard method but the studies in gas system are still growing. This study aims to explore the effect of different type immobilized sulfurs toward the mercury vapor uptake in a mi... see more
