Performance of Polyvinyl Alcohol/Bagasse Fibre Foamed Composites as Cushion Packaging Materials

This work was designed to determine the mechanical properties and static cushioning performance of polyvinyl alcohol (PVA)/bagasse fibre foam composites with a multiple-factor experiment. Scanning electron microscopy (SEM) analysis and static cushioning tests were performed on the foamed composites and the results were compared with those of commonly used expanded polystyrene (EPS). The results were as follows: the materials had a mainly open cell structure, and bagasse fibre had good compatibility with PVA foam. With increasing PVA content, the mechanical properties of the system improved. The mechanical properties and static cushioning properties of the foam composite almost approached those of EPS. In addition, a small amount of sodium tetraborate obviously regulated the foaming ratio of foamed composites. With increasing sodium tetraborate content, the mechanical properties of foamed composites were enhanced. The yield strength and Young’s modulus of the material prepared by reducing the water content to 80.19 wt% were too high and not suitable for cushioned packaging of light and fragile products.

Investigation on Optimization of Mechanical Properties of Bagasse Reinforced Epoxy Composite Using Grey Relational Analysis

In this present study, the fabrication of polymer composite matrix has been designed using the epoxy matrix and bagasse fibre. The most crucial operating parameters such as chemical treatment, volume fraction of fibre content, concentration of chemical, and soaking hours of fibre in the chemical were evaluated. Based on these parameters, the outcomes such as tensile strength, flexural strength, impact strength, hardness, inter laminar shear strength, and coefficient of friction were measured and evaluated. The optimisation of all the operating parameters against the various outcome parameters has been performed by Grey relational analysis. The analysis assist in making decisionto select the best optimum parameters by assigning the rank for the combined mechanical properties with respect to different operating input variables. The optimum combination of operating parameters determined was (i) chemical treatment – KMnO4 (ii) Volume fraction of fibre content – 30 wt % (iii) Concentration of chemical – 7% and (iv) soaking hours of fibre – 6 hours.

Studies on effect of sugarcane bagasse fibre on mechanical properties and workability of low calcium fly ash and slag based geopolymer concrete

Individuals from the group of inorganic polymers are known as geopolymers. The geopolymer material's compound organisation is similar to that of typical zeolitic materials, however the microstructure is undefined rather than translucent. The polymerisation interaction includes a considerably quick substance response under antacid condition on Si-Al minerals and that meets the basic properties of concrete as well as falls under classification of manageability. Utilization of various fibres like steel, glass, sugarcane bagasse etc, significantly influences fresh and hardened properties of concrete. Sugarcane bagasse fibre is a by-product from sugar industries and can be used as a fibre in concrete. The target of this paper is to study an effect of sugarcane bagasse fibre on mechanical properties such as compressive, tensile and flexural sgength and also the workability of low calcium fly ash (Class-F) and slag based geopolymer concrete of G40 grade which is équivalent to M40.. Sugarcane baggase ash fibre has been used for both the concencrte G40 and M40 as 0.5%,1%,1.5%,2%. All the samples were casted and oven cured at 60o for 24 hours after one day rest period and remaining days cured in an ambient temperature, then tested on 3rd, 7th and 28th day to assess the mechanical properties, such as Compressive, Tensile, and Flexure strength. The results were compared among controlled concrete (CC), controlled concrete with sugarcane bagasse fibre (CCF), geopolymer concrete (GPC) and geopolymer concrete with sugarcane bagasse fibre (GPCF). The results revealed that with addition of SCBF, the mechanical properties have been enhanced significantly.

Effect of Sugarcane Bagasse Fibre on the Behavior of Geopolymer Concrete under Sulphate Attack

The use of various fibres such as steel, glass, sugarcane bagasse, and others has a considerable impact on the fresh and hardened properties of concrete. Sugarcane bagasse fibre is a byproduct from the sugarcane industry that can be reused as a concrete fibre. This paper objective is to work on the behaviour of sugarcane bagasse fibre on low calcium fly ash and slag based geopolymer concrete of G40 which is equivalent to M40 grade, when it is exposed to 5% sulphate attack with the help of experiments. The specimens were casted, GPC and GPCF Cured in an oven at 60 ° C for 24 hours, then let to cure in the atmosphere until the test is complete. After 28 days, the specimens were immersed in sulphates such as Na2SO4 and MgSO4 for 15, 45, and 75 days, and then tested according to codal standards on 15, 45, and 75 days. The comparisons were made in a controlled concrete environment (CC), controlled concrete with sugarcane bagasse fibre (CCF), geopolymer concrete (GPC) and geopolymer concrete with sugarcane bagasse fibre (GPCF). From the results it is observed that CCF and GPCF showed more resistant than CC and GPC when it is subjected to sulphate attack.

Studies on the acid attack resistance of sugarcane bagasse fibre geopolymer concrete

It is necessary to reduce the effect of carbon dioxide, as failure to do so will result in global warming. In this instance, researchers have begun looking for sustainable building materials. Industrial byproducts like flyash, GGBS, silica (SiO2) are used to make geopolymer concrete. To produce binders alkali liquids can be used to react with aluminate, silica and with flyash, alkali activated concrete is made by mixing binders with coarse and fine particles and forming a mixture.. In addition to this concrete sugarcane bagasse fibres is added to improve the properties of concrete. The main objective of this paper is to study the durability properties in terms of like acid attack resistance on sugarcane bagasse fibre reinforced geopolymer concrete (GPCF) of G40 equivalent M40 when it is exposed to 5% acids attack with the help of experiments. The test specimens were casted and then cured in an oven at 60°C for 24 hours after one day rest period. The test specimens were kept at room temperature for the remainder of the time. After 28 days, the specimens were immersed in acids such as HCL and H2SO4 for 15, 45, and 75 days before being tested according to codal procedures on the 15th, 45th, and 75th days, and the results were compared to controlled concrete (CC), sugarcane bagasse fibre reinforced controlled concrete (CCF), and geopolymer concrete (GPC)). From the results it is observed that CCF and GPCF showed more resistant than CC and GPC when it is subjected to acids attack.

Effect of sugarcane bagasse fibre on the flexural behavior of geopolymer concrete RCC beams

CO2 is released into the atmosphere during the manufacture of Ordinary Portland Cement (OPC). Fly ash, a by-product of the coal industry, is used to replace OPC in concrete. It contains a lot of silicate gel and is mixed with an alkaline solution to make good concrete. Increased fly ash fineness improves compressive strength while lowering porosity. Advances in modern bio technology is possible freedoms for monetary use of agro-mechanical deposits like sugarcane bagasse ash and fibre. The flexural behaviour of Geopolymer Concrete RCC beams with and without sugarcane bagasse fibre, i.e. GPC and GPCF of G 40 grade, equal to M40, is presented in this study. The 150*150 mm beam is cast across a 1,200 mm effective span and tested for failure under static loads. The ultimate load and load displacement responses of GPC structural elements with and without fibre are measured and compared to normal GPC and conventional concrete elements. The findings suggest that SCBF improves the flexural strength, service load, and peak load of GPC elements.
