The paper presents an experimental study on the production of non-fired ceramic tiles from rice husk ash (RHA) and green glass cullet (GGC) composites as a novel eco-friendly material. Eighteen mixture formulations were constructed as compared to control formula, specimens were uniaxially pressed at 10 MPa and then cured at room temperature for 7 and 28 days. Non-fired tiles (formula A4, B11, and C17) containing 20% GGC were mixed with 0%, 5%, and 10% RHA. The modulus of rupture can be increased by 87.23%, 48.8%, and 19.4%, respectively, at 28 days of curing as compared to control formula. These results were also coherent with microstructure characterization by scanning electron microscopy (SEM). Furthermore, formula A4 and C17 were selected to compare energy costs with wall tiles fired at 950°C. They were the same amount of energy-saving costs by 5.19 USD/m2. From these results, the new eco-friendly products can produce with a combination of RHA and GGC wastes which can enhance the physical properties due to the pozzolanic reaction. Moreover, the proposed non-fired ceramic tiles can conserve energy and reduce manufacturing costs.

Intensive Approach

Infrastructural developments are inevitable for the developing countries and hence the production of sustainable building materials is promoted worldwide. Sustainable development in the vicinity of tiles is bewildered for more than a decade. Production of conventional tiles such as cement concrete tiles, clay tiles and ceramic tiles is energy intensive approach and levies lot of strain over the adjunct ecosystem. On the other hand there are serious problems related to the disposal of flyash, Rice Husk Ash throughout the world. An approach has been taken to synthesis tiles based on these industrial byproducts as the base materials through Geopolymer technology. In this work, Geopolymer mortar after heat curing is applied as tiles. In this work, Flyash is replaced by Rice Husk Ash in various proportions such as 20, 40, 60, 80 and 100 percent. Tests such as workability, flatness, straightness, perpendicularity, water absorption, modulus of rupture and abrasion are conducted and fair results are obtained. This research also portrays the effect of Rise Husk Ash addition over the flyash based Geopolymer binder in the utility as tiles. The findings of this research work encourages the development of energy efficient tiles using industrial wastes. Keywords: Geopolymer, Rice Husk Ash, Tiles

ABSTRACTEarth stabilization, using two by-products available in Burkina Faso: Calcium Carbide Residue (CCR) and Rice Husk Ash (RHA), improved the performance of compressed earth blocks (CEBs). The effect of adding CCR or CCR: RHA (in various ratios) to the clayey earth was investigated. CEBs were molded by manually compressing moisturized mixtures of earthen materials and 0-15 % CCR or CCR: RHA (various ratios) with respect to the weight of earthen material. The results showed that, with 15 % CCR: RHA in 7: 3 ratio, the compressive strength of CEBs (6.6 MPa) is three times that of the CEBs containing 15 % CCR alone (2.2 MPa). This improvement was related to the pozzolanic reaction between CCR, clay and RHA. These CEBs comply with the requirement for wall construction of two-storey housing.

Recently, incorporation of cement replacement material (CRM) in concrete has gained considerable attention throughout the world. It is known that the commonly used CRM in current concrete industry is silica fume (SF), pulverized fuel ash (PFA) and rice husk ash (RHA). RHA is an agricultural waste from rice milling process. Rice farming activities is one of the main crops planted in Malaysia and therefore, the rice husk abundantly generated every year. RHA exhibits positive pozzolanic reaction during concrete strength development. The material contains amorphous silica and hence it contributed towards enhancement of various concrete properties. This paper presents a short review of RHA properties as CRM and pozzolanic reaction determination.

Cement Strength

Designing a slurry with adequate strength resistance is a major objective in oil and gas completion job. Various studies and research confirms that Compressive Strength (CS) and Shear Bond Strength (SBS) are two parameter which is imperative in describing cement strength in well cementing job. This experimental study introduces a Rice Husk Ash (RHA), an alternative cement additive derived from organic waste. RHA rich in silicon oxide (SiO2) and has a pozzolanic reaction, which is correlated in enhancing cement strength. Serial cement samples with various concentration of RHA were prepared to investigate the effect of RHA concentration to CS and SBS. All samples were then Dried for 24 hours in room condition after completing mixing and molding process. A Biaxial Loading test was then performed to all samples to determine the CS and SBS values by using hydraulic press apparatus. Results from the loading test generally indicate an enhancement of CS and SBS for samples with 31%, 32%, 33%, and 34% RHA. An indication of higher CS and SBS is not found for sample with 35% RHA, comparing with 34% RHA. Thus, 34% RHA is the optimum concentration for theses study, which yield 1312. psi of CS and 158.16 psi of SBS.  Through this study, there is an opportunity for transforming waste material into alternative additive with higher economic value.

Pozzolanic Properties

Self-compacting concrete (SCC) is a new concept of concrete mix which flows in a formwork and consolidates itself without the need for compaction. Effectively compacting concrete can be very difficult especially in areas with a high number of reinforcement. Millet Husk Ash (MHA) and Rice Husk Ash (RHA) are agricultural waste materials obtained from farm and burnt to ashes to discard them since they are environmental waste. This research is focused on finding the pozzolanic potentials of MHA and RHA as a mineral additive in SCC to see if it will improve its properties rather than discarding them as environmental waste. Laboratory investigations were carried out on normally vibrated concrete (NVC) and SCC using MHA and RHA as an additive at a 10 % replacement with cement. Workability tests were carried out following the BS specifications. ASTM 293 C was used for the Flexural Capacity test on the beam specimen. The Results of the workability tests using MHA and RHA as mineral additive are within the specified standard values. The compressive strength test also revealed that the SCC using MHA is about 12.8 % higher than the RHA and NVC at 28 days with densities of 2487.5, 2516.5 and 2437.5kg/m<sup>3</sup> respectively. The Modulus of Rupture (MoR) and Split Tensile strength for MHA is 0-19.2 % and 17.2-22.2 % higher than the RHA and NVC respectively. It was concluded that the improvement in the pozzolanic properties of MHA and RHA may be due to the content of Lime (CaO), Silica ((SiO<sub>2</sub>)), Alumina (Al<sub>2</sub>O<sub>3</sub>), Iron oxide (Fe<sub>2</sub>O<sub>3</sub>) being greater than 70 % and in an accordance with BS 618 code. It is concluded that the MHA and RHA can find suitable applications in the SCC as a mineral additive rather than discarding them as environmental waste.

Concrete which is widely used material in the construction industry, has a carbon footprint. Approximately 10% of global Carbon Dioxide (CO2) gas is emitted during the production of cement which is vital ingredient of concrete. The increase in production of cement affects global warming and climate change. Therefore, many have attempts have been made to develop green and sustainable concrete by utilizing different waste materials. With the utilization of waste materials as cement replacement, the CO2 gas emissions can be reduced as well as resolve the environmental issues that the inhabitants face during the disposal of such waste materials. This paper reviews the potential and innovative utilization of Rice Husk Ash (RHA) and Eggshells as partial cement replacement to develop green concrete. RHA which is rich in silica and eggshells contain identical amount of calcium oxide as cement, when finely grinded and used together as partial cement replacement, can trigger a pozzolanic reaction, in which silica reacts with calcium oxide resulting in the formation of calcium silicates which are responsible for achieving higher strengths.

A new approach has been demonstrated for the synthesis of solid ammonium sulphate attached to silica rice husk ash. The 3-(aminopropyl)triethoxysilane was immobilized onto silica at room temperature to functionalize the silica with ammine end groups (–NH2). The amine group was sulphated with sulphuric acid to produce a novel micro-rod-like shaped acidic catalyst (as seen with TEM) designated RHNH3SO4H (RH = rice husk). The TGA analysis shows that the catalyst is stable at temperatures below 200°C. The acidity measurement of the catalyst indicates that it has Brønsted acid sites. Cellulose extracted from waste of rice husk and cellulose extracted from office paper were hydrolysed to glucose in 6 h, and the glucose was hydrolysed afterwards to other products within 13 h. The catalyst is reusable many times without a significant loss of catalytic activity.
