Rice Husk Flour

Different properties (tensile strength, elongation, modulus, impact strength) of rice husk (RH) reinforced polypropylene (PP) coupled by Maleic-Anhydride grafted Polypropylene (MAgPP) have been investigated. MAgPP is an effective coupling agent, not only in cellulosic-fibre filled polyolefine composites, but in rice husk flour filled polypropylene composite systems as well. It gives a utilizable construction polymer matrix composite (PMC) material even at a 40 wt.% RH filling degree. The strength and modulus increases by adding the rice husk but the elongation decreases in a non-monotonic way. Micrographs shows weak coupling in between RH and PP without MAgPP.

The Cost

This research presents a comparative cost and strength analysis of rice husk concrete block which is aimed at reducing the cost of concrete production and emphasizing environmentally and friendly sustainable materials. Concrete block materials consist of cement, filler, and rice husk. Tests were performed to compare the strength and cost of seven cement rice husk weight ratios designated ranging from 0.67 to 2.00 with constant water cement ration of 0.4. Samples have been tested for 28-day strength. The analysis of the results has showed that the higher proportions of rice husk correspond to decreased strength dan cost polynomially. At 134% proportion of rice husk, it is optimum value for rice husk concrete block. In this point, the compressive strength satisfies the standard. Also, water absorption of 16,04% justifies the maximum standard. Overall, the cost of 134% RH concrete is Rp 511,809 per m3 which is 42.5% cheaper than normal concrete block.

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.
