Abstract
Concrete provides a high degree of protection against corrosion of embedded steel reinforcement. Owing to the harsh environmental conditions and the presence of aggressive elements from the marine environment, deteriorating corrosion affects the durability of reinforced concrete structures. This study evaluated the effectiveness of bamboo leaf ash BLASH as a supplementary cementing material or admixture with Portland cement to improve the durability of reinforced concrete structures. Specimens of 0, 10, 15, and 20% BLASH mixtures were prepared using 16, 20, and 25 mm steel reinforcements. A total of 100 cylindrical specimens were cast and used in this study. The specimens were accelerated by corrosion using impressed current techniques and a galvanostatic method in a simulated environment. The results show that specimens with a BLASH content of 10% exhibited superior performance and exhibited longer corrosion initiation and propagation times. It has a higher resistance to acid penetration and lower corrosion rates. The crack parameters of the specimen with BLASH admixtures, such as the crack width and crack frequency, were negligible. The use of BLASH as an admixture strengthens its durability and improves its residual strength and serviceability. Doi: 10.28991/cej-2021-03091707 Full Text: PDF
Highlights
Concrete is a composite material consisting of a binding medium within which aggregates are embedded [1]
There are relatively few studies on the technological use of bamboo leaf ash reported in the literature, only a few studies have been conducted to evaluate the effectiveness of bamboo leaf ash as a corrosion inhibitor of reinforced concrete structures, those exposed to coastal areas
The compressive strength of blended cement with BLASH content increased with time, their values were lower than those of the control specimen (0% bamboo leaf ash)
Summary
Concrete is a composite material consisting of a binding medium within which aggregates are embedded [1]. There are relatively few studies on the technological use of bamboo leaf ash reported in the literature, only a few studies have been conducted to evaluate the effectiveness of bamboo leaf ash as a corrosion inhibitor of reinforced concrete structures, those exposed to coastal areas. This experimental study aimed to assess the effectiveness of BLASH in establishing mixtures with high durability and high resistance to corrosion, which helps to lengthen the design life and serviceability of structures exposed to a severely aggressive environment. The effectiveness of bamboo leaf ash BLASH against corrosion deterioration of structures exposed to excessive marine environments
