Characterization of the Mechanical Properties of Concrete with Addition of Bamboo Fiber - Porto Nacional/TO

Abstract

The search for materials which do not unduly the environment by reducing the cost of production is increasing throughout the world. In the construction sector, concrete is the most consumed material in the world. Its production with bamboo fiber addition can contribute to minimize environmental impacts and production costs by reducing the extraction of natural resources. This study aimed to investigate the mechanical properties of bamboo located in the region of Porto Nacional -TO, Brazil and its application as a binder (Portland cement) in the production of concrete. The research aimed at results that allowed to verify the behavior of the concrete in relation to its uniaxial compressive strength at 28 days of the specimens produced with the addition of bamboo fibers, replacing the cement binder. Bamboo fibers and aggregates were characterized and evaluated according to the material and defined by the trait (1: 1.68: 2.68: 0.482), with replacement percentages set at 3%, 4% and 5%. Therefore, through the tests that were performed, the possibility of replacing the Portland cement binder with natural polymeric bamboo fibers was verified, which proved to be viable and quite advantageous not only for the environmental and economic, but also in the material strength gain.

Experimental Investigation on Interfacial Defect Detection for SCCS with Different Contact NDT Technical

“…The quantity of water used in the concretes with admixtures included the liquid portion of the admixture without considering the solid portion. All the concretes were produced in a stationary concrete mixer using the same procedures [9], sequence, and mixing time. Table 3 shows the densities of the produced concretes.…”

“…Lightweight concrete is widely used in the construction industry [5] and is categorized as lightweight aggregates, aerated, and foamed concrete. Lightweight concrete can be produced by adding lighter materials to the mixture to replace conventional materials such as glass foams [6,8], bamboo fibers [9], waste PET bottles [10], glass bottles [11], or the addition of air-entraining admixtures (AEAs), which are used in order to create macro pores that reduce the pressure of ice formation in the binding matrix. Air-entraining additives were discovered in the 1930s in New York City after concrete collapsed, and air-entraining agents are primarily used to ensure a quality air void system that protects concrete from frost damage.…”

Production of Glass Foam in a Microwave Oven Using Agro-Industrial Waste as Raw Material

“…The global trend towards building taller structures has escalated concrete production, making it the most utilized material worldwide [11][12][13][14], with annual production nearing 10 billion cubic meters [15]. Research has indicated that construction processes can integrate various waste materials into concrete, such as vitreous foams [7,8], bamboo fibers [16], PET bottles [17], and glass bottles [18], to mitigate environmental impacts.…”

Investigação das propriedades do concreto convencional com adição da fibra de bambu e da substituição parcial do cimento pelo Metacaulim

“…Quando comparado o concreto convencional com o concreto reforçado com fibra de bambu, a resistência à compressão do concreto reforçado com fibra de bambu a 0,5%, 1%, 1,5%, e 2% aumentou, mas reduziu para 2,5% em comparação com outras proporções de fibras. Ferreira et al (2019) investigou os resultados da resistência à compressão uniaxial aos 28 dias dos corpos-de-prova produzidos com a substituição parcial da areia pela fibra de bambu. As fibras de bambu e agregados foram caracterizados e avaliados de acordo com o material e definido pelo traço (1: 1,68: 2,68: 0,482), com percentuais de substituição parcial da areia pela fibra de bambu nas concentrações de 3%, 4% e 5%.…”
