The aim of this work is to study the feasibility of preparation of fly ash based geopolymer using sodium water glass from agricultural waste as alternative activators. Rice husk ash and bagasse ash were used as raw materials for producing sodium water glass solution. The sodium water glass were produced by mixing rice husk ash and bagasse ash with NaOH in ball mill and boiling. The prepared sodium water glass were analyzed and used in geopolymer preparation process. The geopolymer paste were prepared by adding the obtained water glass and NaOH with fly ash. After cured at ambient temperature for 7 days, mechanical properties were investigated. Bonding and phases of the geopolymer were also characterized. The geopolymer from rice husk ash presented highest compressive strength about 23 MPa while the greatest for bagasse ash was about 16 MPa.

This research assessed the effect of Nigerian rice husk ash (RHA) and calcium chloride (CaCl2) as partial replacement of cement in concrete grade 20. Rice husk ash (RHA) is obtained by combustion of rice husk in a controlled temperature. The replacement of OPC with rice husk ash (RHA) were 0%, 5%, 10%, 15% and 20%. 1% of Calcium Chloride was blended with OPC/RHA in all the test specimens except from control mix. Concrete cubes of sizes 150mm x 150mm x 150mm were cast and cured in water for 7, 14 and 28 days respectively. Slump test was conducted on fresh concrete while density test and compressive strength test were conducted on hardened concrete. The slump results revealed that the concrete becomes less workable (stiff) as percentage increases. The compressive strength result at 28 days revealed that 5%RHA/1%CaCl2 have the highest strength of 26.82N/mm2 while 20%RHA/1%CaCl2 have the lowest strength (21.48N/mm2). Integration of 5%RHA/1%CaCl2 and 10%RHA/1%CaCl2 as cement replacement will produce a concrete of higher compressive strength compared to conventional concrete in grade 20 concrete.

Abstract.   In the process of producing light brick, there is ‘mixed foam’ agent to reduce the value of its density, therefore it can reduce the values of compressive strength. To reduce its density and increase the value of pressure, the variations and types of fillers must match the composition. The manufacture of light brick type CLC (Cellular Lightweight Concrete) has been carried out with several variations and types of fillers to compare the values ​​of compressive strength and density. The fillers are as follows: Water Hyacinth, Banana Midrib, and Wood Shavings based on gold processing waste (GPW). The compressive strength and density test results on various filler percentages are as follows: 1). Water hyacinth at the percentage of 0%, 15%, 30%, 45%, 60% has compressive strength: (2.43; 0.73; 0.69; 0.59; 0.65) MPa while the densities are ( 1.62; 1.20; 1.41; 1.13; 1.20) gr / cm3. 2). Banana midrib with variations are: 0-4 midribs has compressive strength: (2.43; 1.25; 1.68; 2.13; 1.32) MPa and its densities are (1.62; 1.29; 1.12; 1.16; 1.25) gr / cm3. 3). Wood shavings with percentage: 0%, 25%, 50%, 75% have compressive strength: (2.43; 1.39; 2.04; 1.72) MPa and their densities: (1.62; 1, 21; 1.26; 1.20) gr / cm3. The results showed that the best compressive strength was produced by the filler from wood shavings with an average of 1.85 MPa and a density of 1.31 gr / cm3. The lowest density was obtained from the banana midrib filler which was 1.29 gr / cm3 with a compressive strength of 1.76 MPa. It can be concluded that light brick is best suited to wood shavings fillers.

The use of bricks in the world of construction, both as structural and non-structural elements, cannot be replaced. This can be seen from the many construction projects that use bricks as walls in building and housing construction, fences, channels, and foundations. Bricks are made from a mixture of soil and water. In this study, the process of making bricks will be tried to mix the soil with the additional material of rice husk ash to determine the effect of changes in the mechanical properties of the bricks in terms of the shrinkage test and compressive strength test. The soil sample used is a type of clay soil originating from Suakarsa Village, Teluk Gelam District, Ogan Komering Ilir Regency. This study used a sample of block-shaped bricks with a length of 19.5 cm, a width of 9.5 cm, and a height of 9 cm. The variations in the composition of rice husk ash added were 0%, 3%, 4%, 5% and 6%. The addition of rice husk ash with a composition percentage of 3% to 6% can affect the mechanical properties of the bricks, namely reducing burnt losses and increasing the compressive strength of the bricks. The minimum burn value was achieved in the percentage of rice husk ash with a variation of 6%, namely by 37.55% burn loss. The optimum compressive strength value is achieved in the percentage of rice husk ash with a variation of 3% with 14 days of age, the compressive strength value is 76.88 Kg / cm². Key Words : Bricks, Rice Husk Ash, Compressive Strength.

This research was carried out to investigate various physical properties of Rice Husk Ash (RHA) and, some physical and mechanical properties of concrete incorporating RHA in different proportions. The concrete specimens were tested at 7, 21 and 28 days after curing. Test results revealed that the specific gravity of RHA was found lower than that of sand. The density of concrete containing RHA was recorded between 80-110 lb.ft-3, which is lower than conventional concrete. Water absorption was found increasing with the increase of RHA content in concrete specimens. There were significant variations in compressive strength values of concrete containing 5%, 10% and 20% volume of RHA. The compressive strength of 5% RHA specimen was 150-200% higher than that of other specimens. Hence, upto 5% replacement of RHA could be recommended for making normal lightweight concrete. The splitting tensile strength was about 9-10% of compressive strength. It was concluded that upto 5% RHA can be used effectively in making normal lightweight concrete. The higher percentage of RHA could be used in making non-structural concrete where the strength of concrete is not concerned.J. Environ. Sci. & Natural Resources, 9(1): 29-33 2016

Foamed Concrete

Foamed concrete is lightweight concrete with a green material concept. One of cement-based materials is Microwave Incinerated Rice Husk Ash (MIRHA) foamed concrete (FC) as a pozzolanic material, that is interesting to be studies since the information about the ingredient can be used to understand the product behaviors. This study is more focused on the investigation towards the effect of composer of MIRHA FC on the workability and compressive strength. The mix proportion of the MIRHA FC here was designed by means of Taguchi method with L16 orthogonal array through five parameters (MIRHA contents, water cementitious ratio (w/c), sand cement ratio (s/c), superplasticizer (SP) content, and foam content). The mixtures were tested both in fresh and hardened states to fulfill the technical requirement of FC. It was also supported by the analysis on the characteristics of concretes including its workability and compressive strength. Based on the analysis, it is shown MIRHA is capable of enhancing FC workability and strength.
