Physical And Mechanical Characteristics

In this research the aim was produce a particleboard with alternative materials and evaluated its physical and mechanical characteristics. The raw materials used are residues from sucarcane bagasse (SC) (Saccharum officinarum) and stem leaves of bamboo (B) (Dendrocalamus giganteus), bonded with a bi component adhesive based on castor oil. It was produced particleboards with five different traces: 100% SC, 75% SC+25% B, 50% SC+50% B, 25% SC +75%B and 100 % B. Their physical and mechanical characteristics were evaluated accordingly to Brazilian standard NBR 14810-3. Regarding the results obtained, it can be detached that for physical and mechanical evaluation it is evident a negative relation among the amount the sugarcane bagasse and their physical and mechanical characteristics, that is particleboards with low concentrations of sugarcane bagasse had better results. However all particleboards could be recommended for use as sealing particleboards in the segment of civil construction.

The sugarcane industry generates huge amounts of sugarcane bagasse ashes (SCBA). This work investigates the incorporation of a SCBA waste as an alternative raw material into a clay body, replacing natural clay material by up to 20 wt.%. Clay ceramic pieces were produced by uniaxial pressing and fired at temperatures varying from 700 to 1100 ºC. The technological properties of the clay ceramic pieces (linear shrinkage, apparent density, water absorption, and tensile strength) as function of the firing temperature and waste addition are investigated. The phase evolution during firing was followed by X-ray diffraction. The results showed that the SCBA waste could be incorporated into red ceramics (bricks and roofing tiles) in partial replacement for natural clay material. These results confirm the feasibility of valorisation of SCBA waste to produce red ceramic. This use of SCBA can also contribute greatly to reducing the environmental problems of the sugarcane industry, and also save the sources of natural raw materials used in the ceramic industry.

In recent years the production of products derived from wood and bamboo are increasing, due to the search for a more rational exploitation of these raw materials. Amongst these products, the particleboards production combine sustainability and rationality in the use of these materials. In this context, this work has the objective to study the application of alternative raw materials in the manufacture of Medium Density Particleboards (MDP), using residues from industrial processimg of coffee and bamboo. MDP had been produced with particles of giganteus bamboo of the Dendrocalamus species and particle of coffee rind in the intermediate layer of the particleboard, bonded with polyurethane resin based on castor oil. The physical and mechanical characterization was carried out accordingly to NBR 14810-3 (2006). The physical properties evaluated were: of water absorption for 2h and 24h; thickness swallowing for 2h and 24h; density, humidity content. The mechanical properties evaluated were: Tensile strength, static bending (MOR and MOE). The results were compared with NBR 14810-2 (2006) and also with the ANSI A208-1 (1993). The physical performance of these particleboards was below the values recommend by the Brazilian norm. Also the mechanical characteristics are not improve, demonstrating that the inclusion of coffee rind did not benefit the physical characteristics and nor the mechanical ones. However it can be used as construction materials for partitions and ceiling panels.

The article deals with the modification of cement compositions by a complex of modifiers, including superplasticizers and finely dispersed mineral fillers (micro fillers), based on local raw materials and by-products of the industry, as well as being capable of improving the physical and mechanical characteristics of cement concretes and solutions. The expediency of joint application of finely dispersed fillers and superplasticizers for obtaining materials with high performance characteristics is shown. The studies described in the article are aimed at expanding the raw materials base of mineral additives in combination with superplasticizers and studying their behavior in the cement system. As finely dispersed mineral additives, the following were used in the work: ground limestone from the overburden from the Mazulsky deposit, waste from sawing the jadeite of the Kashkaraksky deposit, a pulverized fraction of waste from crushing the Berezovskoye gravel, and Novosibirsk microsilica. It is shown that the introduction of the waste from sawing jadeite into the composition of the cement, along with microsilica, leads to increasing strength at bending and compression at 28 days. In the process of manufacturing a concrete and mortar mixture with the addition of limestone flour, increased gas emission was visually observed. The interaction was observed between the finely dispersed limestone flour with additives of plasticizing effect with the observed emission of complex gases, such as ammonium hydroxide, ammonium nitrate, and others.

The obtaining carbonized material experimental studies’ results based on lime carbonate systems by 3D inkjet printing are presented. Some types of materials used as binders for inorganic binders have been studied. An effective method of hardening the model obtained in the 3D printing process is determined. The physical and mechanical characteristics of the prototypes hardened in the carbon dioxide medium or high concentration are determined. It was found that artificial carbonization of the samples obtained on various types of binders for 90 min contributes to the formation of a fairly strong structure of insoluble calcium carbonate, the hydrated lime carbonation product, and the carbonization degree depends on the type of binder and its mass fraction in the solution. The most effective types of binders were selected and the optimal content of the studied binders in the solution was determined.

ABSTRACT Sugarcane bagasse, a waste material generated by the sugar-alcohol industry, is rich in lignocellulosic components such as cellulose and hemicellulose. The bagasse can be employed as a raw material in the pulp and paper industry, but is currently rarely used for this purpose, due to the availability of traditional sources such as Eucalyptus and Pinus. The objective of this work was to compare the physical and mechanical properties of papers produced using the cellulose extracted from sugarcane, Eucalyptus, and Pinus by the Kraft method. Four paper samples were produced using cellulose obtained from the following fiber sources: (I) 100% sugarcane bagasse; (II) 100% Eucalyptus; (III) 75% Eucalyptus + 25% Pinus; (IV) 75% sugarcane bagasse + 25% Pinus. Physical and mechanical tests were performed based on regulatory methodologies of the paper industry. The results indicated that the physical and mechanical characteristics of the paper produced from the sugarcane cellulose were similar to those of the traditional paper produced using Eucalyptus. Particular features such as good tearing resistance and tensile strength, as well as increased porosity and moisture, could be adjusted according to the intended use of the paper. Therefore, sugarcane bagasse can be considered a sustainable alternative to Eucalyptus and Pinus for the production of high quality paper, adding value to this agricultural residue.

The problem of proper disposal of solid waste generated in different industrial processes is one of worldwide environmental concerns nowadays. Thus, this study aimed to establish a new alternative for the disposal of two agro-industrial residues employing them to produce particleboard for different purposes in building construction. The focus was given to the reuse of the sugarcane bagasse (SB) originated during the processing ofSaccharum officinarumfor sugar and ethanol production, and bamboo stem leaves ofDendrocalamus giganteus(BB). For this, six particleboards were produced in the following compositions: with 100% SB, 75% SB + 25% BB, 50% SB+50% BB, 40% SB +60 BB, 25% SB+ 75% BB and 100% BB in the total mass of the composites. The particleboards physical characterization followed Brazilian Standard ABNT NBR 14810-3 to density, moisture content and water absorption. Results showed these raw materials are compatible to particleboard production.
