Crack Pattern of Lightweight Concrete under Compression and Tensile Test

Abstract

Examining the crack pattern of lightweight concrete under compressive and tensile loads is the goal of this study. A lightweight concrete specimen was made using foam, fine aggregate, and Portland Composite Cement. Foam agent and water are combined in a 3:10 ratio to produce foam. There were three different foam volume variants used: 15.7 liters, 25.12 liters, and 37.68 liters. As a sample, a cylinder with dimensions of 10 cm by 20 cm was employed. Using compressive and indirect tensile strength tests at curing ages of 3, 7, and 28 days, the crack pattern of lightweight concrete was assessed. The findings revealed that the fracture pattern for the compressive and indirect tensile strength tests was almost same; because the crack pattern was parallel to the direction of the load, it was categorized as a columnar crack pattern at 3, 7, and 28 days. Throughout time, the frequency of crack patterns in lightweight concrete decreased. It might be said that concrete becomes more resistant as it ages.

Optimization of Asphalt Content Through Marshall Characteristics Using Modified Asbuton

“…The presence of finer solid minerals (filler) of modified Asbuton filled gaps left by water in the various asphalt mixtures. Consequently, various asphalt mixtures including modified Asbuton, as indicated in Tables 10 through 12, have sufficient stability with resistance to deformation and strength to overcome the tensile stress.…”

“…Israil, Tjaronge M.W., Ali N., and Djamaluddin R. (2016) [12] investigated an additional advantage of using a binder derived from the extraction of Buton asphalt. Full extraction of LGA or BGA and the creation of emulsified asphalt are among the outcomes achieved.…”

“…Numerous studies have documented the use of Buton asphalt as a material substitute for petroleum bitumen. By using these abundant natural resources, there is a prospect to enhance the stability and effectiveness of asphalt mixtures [10][11][12][13][14][15][16][17]. Modified Buton asphalt, a processed semi-extracted from natural resources, has also shown potential as a binder in asphalt mixtures [18].…”
