Properties of Cement Mortar Consisting Raw Rice Husk

Most of the rice husk is disposed with no further concern and this has caused waste disposal problems. Burning rice husk can cause health and environmental problem. Rice husk ash has been widely used for concrete technology application as additive in concrete mixture. However there is lack of study on the usage of raw rice husk. This paper presents the experimental on the properties of cement mortar consisting raw rice husk which focused on the porosity and density. Specimens were prepared by incorporating different percentage of rice husk with mortar. Summation of 10 mixes has been investigated to determine the compressive strength, density, porosity and water absorption. As the main purpose of the rice husk cement mortar is for drainage material, the main characteristics needed are porosity and lightweight. From the results, it is concluded that the higher percentage of rice husk used, will decreased the compressive strength and density and increased the porosity of rice husk cement mortar.

This research studies the potential for using waste ash from industrial and agricultural by-products as a pozzolanic material. Classified fly ash (FA) and ground rice husk ash (RA) were the materials used. Water requirement, compressive strength and porosity of cement mortar were investigated. Test results indicated that FA and RA (waste ash) have a high potential to be used as a good pozzolanic material. The water requirement of mortar mix decreases with the increases in fly ash content. For ground rice husk ash (RA), the water requirement of mortar mix increases with the increases in rice husk ash content. In addition, the reduction in porosity was associated with the increase in compressive strength.

When properly processed, rice husk ash (RHA) comprises a large amount of SiO2, which exhibits a high pozzolanic activity and acts as a good building filler. In this paper, the effects of rice husk ash content, acid pretreatment, and production regions on the compressive and flexural properties and water absorption of a cement paste were studied. The experimental results showed that the compressive strength of the rice husk ash was the highest with a 10% content level, which was about 16.22% higher than that of the control sample. The rice husk after acid pretreatment displayed a higher strength than that of the sample without the acid treatment, and the rice husk from the Inner Mongolia region indicated a higher strength than that from the Guangdong province. However, the flexural strength of each group was not significantly different from that of the blank control group. The trend observed for the water absorption was similar to that of the compressive strength. The variation in the RHA proportions had the greatest influence on the properties of the paste specimens, followed by the acid pretreatments of the rice husks. The production regions of the rice husks indicated the least influence.

Abstract: In this developing era concrete and cement mortar are widely used by the construction industry, with this development. Large number of industrial wastes are generated and if these wastes are not properly used it will create severe problems, keeping the environment in mind, concrete engineers are trying to find some alternative materials which will not only replaces the cement content but also improves strength of concrete. As we also know that during the manufacturing of cement large amount of Co2 is released into the environment, but if we use such material that will replace the quantity of cement content therefore indirectly, we are contributing towards the prevention of our planet from global warming and other pollutions. Also, in this research work the Rice Husk Ash is used. the rice husk ash obtained from the rice processing units, by adding this product with concrete, not only replaces the cement content but also increases the strength of concrete like compressive strength etc. The Rice husk ash was incorporated with concrete with varying percentages of 2.5% ,5% ,7.5%, & 10%. the proper codal precautions were followed during the manufacture of concrete cubes of 150x150x150mm. it was concluded that the strength of concrete increased by incorporated the rice husk ash.

The purpose of this paper is to discuss the influence of mineral additives i.e. metakaolin, silica fume, rice ash and fly ash incorporating with nanocarbontubes mortar composites. The effects on compressive strength at 28 days were also discussed and presented. Cement content of 500 kg/m3, water/cement ratio of 0.6 and aggregate/cement ratio of 2.75 were adopted for the mix propotion. 1%, 3% and 5% of nanocarbontubes in mortar were combined with 15% of mineral additives. The results show that mixtures of nanocarbontubes with 15% of metakaolin produce better strength compared to normal mortar. Meanwhile with addition of fly ash and rice husk ash the strength were decreased. The electrical resistance for all mixes at 28 days were also discussed and presented. The higher percentages of nanocarbon with addition of all mineral additives resulted in lower electrical resistance properties

The aim of this study is to determine the influence of rice husk ash (RHA) on the engineering properties of fired-clay brick with the present of 10% sand. Temperature 1200°C is selected as the optimum temperature based on the preliminaries study.

Nowadays, interest in developing environmental friendly construction material was increased. As the result, many researches have been done to make use of waste material for engineering purposes. This paper present the results of laboratory experiments on the potential of raw rice husk (RH) cement mortar with addition of foam as drainage material. Mechanical properties which are compressive strength, density, water absorption and porosity have been investigated in order to identify the potential of this material to function as drainage material. Total of eight set of sample were tested to determine those properties. Aqueous foam generated from chemical based foaming agent was used in this study to enhance the drainage ability and also reducing the density of the cement based mixture. More over to simulate the real application at site, an infiltration model was developed to determine the drainage and infiltration characteristic of this material. The permeability of the sample used in the infiltration model has been tested using constant head test to verify the validity of the infiltration model. From the result obtained, it can be concluded that the compressive strength and density of sample decreases with percentage of raw rice husk used while the additional of foam has further reducing the compressive strength and density. Both water absorption and porosity showing the opposite trend compared to the compressive strength. This drainage material can be pre-designed between 1.60N/mm2 – 10.12 N/mm2 for compressive strength, 1392kg/m3 - 1841kg/m3 for density, 21% - 34% for water absorption and 31% - 42% for porosity. From the result of infiltration model, it was observed that this material having good drainage ability with the permeability of 15% foamed rice husk sample is 1.57x10-3.
