Early prevention methods in massive concrete structures to control the heat of hydration and, consequently, the development of cracks due to thermal expansion are important subjects, since these cracks may compromise structural integrity. In the present study, the sugarcane residues in massive concrete were used in order to investigate the reduction in the heat of hydration, the thermal expansion resistance, and also the fresh and mechanical properties of the concrete. The results showed that, b
The use of sugarcane residues in mortar and concrete is believed to contribute to a reduction of costs and environmental problems, such as the reduction of mining of natural aggregates and incorrect disposal of the sugarcane residues. Bagasse fiber has a high water retention rate and thus may be considered as a countermeasure for urban heat islands. Because of these properties, bagasse fiber and bagasse sand were added into the preparation of the interlocking concrete blocks. An investigation of
In this paper the production and characterization of compacted graphite iron alloys in ten chemical compositions is presented. The specimens were obtained through a foundry process performed by a gating system model developed in order to allow the incorporation of silicon, copper and tin. Hardness and tensile tests were performed, as well as microstructural evaluation. Additionally, the results related to the experimental investigation were compared to those obtained from a finite element method
Recently, basalt fiber-reinforced polymer (BFRP) has gained attention in the construction industry because of its worldwide availability and eco-friendly nature. Different from conventional steel bars, BFRP bar do not corrode being an ideal reinforcing material in structures surrounding magnetic fields and marine environments, given its chemical stability. This study investigated the load carrying behavior of concrete beams reinforced with conventional deformed steel bars and seven-bundled BFRP
The use of sugarcane residues in mortar and concrete is believed to contribute to the reduction of environmental problems, such as the reduction of mining of natural aggregates as well as the improper disposal of sugarcane residues. Therefore, in this study, bagasse fiber and bagasse sand were added into the preparation of the interlocking concrete blocks, and the flexural strength and an environmental assessment of the blocks were analyzed. The flexural strength of the blocks was not affected b
For several countries in the world, sugarcane is the primary raw material used in the sugar industry.In some, it is also used for ethanol production.The sugar manufacturing process generates residues.Among them, the sugarcane bagasse is a fibrous residue made from the extraction of the mills' sugarcane broth.The bagasse is used as a primary fuel source in sugar/ethanol mills.After it is burned as fuel in the boilers, it generates residual products composed of unburned bagasse, sand, and ash.The
The hygrothermal and UV radiation influences on shear properties and moisture diffusion aging in polyetherimide (PEI) reinforced with continuous fibers were systematically studied in this research, by using ILSS and losipescu shear tests. The moisture weight gain curves of the PEI composites reinforced with glass fiber and carbon fiber were compared in order to determine the interface effect on moisture absorption. Both composites display similar anomalous diffusion behavior; the PEI reinforced
