Abstract

Currently, a lot of research has been carried out on the utilization of manufacturing industry products, one of which is steel slag as a mixed material for construction and the agricultural industry. One of the uses of steel slag in the construction sector is the manufacture of cement slag, as a mortar mixture, or as a mixture of sub-base layers for road pavement construction. The purpose of this study was to analyze the compressive strength of normal concrete compared to concrete added with slag circum waste as a partial replacement for fine aggregate with variations in the addition of 10% and 20% waste . This study uses an experimental method of planning normal concrete fc' 20 and concrete fc' 20 with variations of 10% and 20% slag circum as a substitute for fine aggregate by comparing the results of the compressive strength of concrete at 7, 14, and 28 days. In this study, it was found that the compressive strength of normal concrete without the addition of circum slag at the age of 7, 14, and 28 days was still better than the compressive strength of concrete at the age of 7, 14, and 28 days with the addition of 10% circum slag, and 20%. .

Abstract

The construction industry in Indonesia is experiencing a significant increase, fueled by government infrastructure development. Concrete is the material of choice as it is easy to use, economical and strong. However, excessive sand mining has a negative impact on the environment, including land degradation and pollution. The increase in construction has led to an increase in construction waste, which, if managed properly, can be profitable. Effective waste management is crucial to address environmental concerns and the utilization of waste lightweight bricks offers a cost-effective and efficient solution. Studies related to the use of waste lightweight bricks as a partial replacement for sand in concrete are highly relevant. The results of compressive strength testing on normal concrete at the age of 28 days obtained based on data analysis and discussion that has been presented in the previous chapter regarding the use of waste lightweight brick powder fibers with variations of 0%, 5%, and 10% are 439 kN (f´c 24.85 Mpa), while variation 1 of 10% lightweight brick powder waste reaches 344 kN (f´c 19.48 Mpa), and variation 2 of 15% lightweight brick powder waste reaches 308 kN (f´c 17.44 Mpa).

Abstract

Roads play a crucial role in local economies, supporting the distribution of goods and the mobility of citizens, but are often damaged by heavy traffic loads, poor drainage and inadequate infrastructure. Asphalt pavement is a popular choice due to its durability and affordable construction costs. Building waste includes construction and demolition waste, containing recyclable to toxic materials. Management of this waste is effective to reduce costs and support industry sustainability, in Indonesia, granite stone waste is widely generated. Analysis of Marshall characteristics in AC-WC mixtures using granite stone powder as a substitute for filler with a variation of 30% resulted in a stability value of 2487 kg, a VMA value of 36.51%, a flow value of 3.35 mm, a VIM value of 26.19% and an MQ value of 742 kg/mm that meets specifications. The VFB test value of 28.27% does not meet the 2018 Bina Marga specifications. While the granite stone powder with a variation of 60% produces a stability value of 2568 kg, a VMA value of 37.31%, a flow value of 3.4 mm, a VIM value of 27.12% and an MQ value of 756 kg/mm that meets the specifications. Meanwhile, the VFB test value of 27.31% does not meet the 2018 Bina Marga specifications. The presentation results of the mix design on cement filler are hot bin I by 17%, hot bin II by 45%, hot bin III by 32%, cement filler 6%, asphalt 6%.

Abstract

Roads as transportation infrastructure play an important role in regional development and are used to transport basic necessities. Certain materials with specific durability are used for road construction, but damage can occur due to natural phenomena, excessive pressure, or material quality. This damage can endanger drivers and often causes accidents. The Bina Marga Road Maintenance Manual lists various types of damage, but this study only focuses on inspections to detect cracks. In Muara Angke, Central Jakarta, one ton of fish bone waste is produced every month from the fish cracker making process. This waste, which produces an unpleasant odor and contains BOD, COD, and TSS, pollutes the environment and makes the 400 m² industrial area unhealthy. Due to lack of skills and technology, local communities have not been able to process or utilize this fish bone waste effectively. The results of Marshall testing on the composition of AC-WC asphalt using fish bone powder waste with variations of fine aggregate substitution of 0%, 25%, and 50%, and asphalt content of 5%, 6%, and 7% did not meet the 2018 Bina Marga specifications for Stability, Void in Air, Marshall Quotient, and Void in Material values. The Marshall characteristics obtained from the mixture with fish bone powder waste are not comparable to the regular AC-WC mixture without waste. In addition, the VIM value for the mixture with 6% asphalt content and waste variations of 0%, 25%, and 50% also did not meet Bina Marga standards. However, all VMA and VFA levels still meet the asphalt and aggregate specification criteria according to Bina Marga 2018.

Abstract

Concrete is the main material in building construction made from a mixture of gravel, sand, cement, and water. This material is the most commonly used in construction. The development of concrete technology brings various innovations to improve its quality, including the addition of additional materials or substitutes such as bamboo reinforcement. Bamboo reinforcement is an alternative because of its abundant availability, easy to obtain, and economical price, thus offering a more affordable construction solution. Research has explored the use of bamboo as a substitute for steel reinforcement, considering that bamboo has a strong mechanical structure. In Indonesia, Petung, wulung, tali, and Ori bamboo are the most commonly used types. Concrete design standards and compressive strength testing are regulated by SNI, with the quality of concrete tested according to SNI 1974-2011 and the increase in concrete flexural strength measured based on SNI 4431-2011. Bamboo reinforced beams at the age of 7 days reached 25 KN, at the age of 14 days reached 28 KN and at the age of 28 days reached 29 KN. Where it can be concluded that the compressive strength of concrete increases at the age of 7 to 28 days. The bagasse reinforced beam at the age of 7 days reached 20 KN, at the age of 14 days reached 23 KN and at the age of 28 days reached 24 KN. Where it can be concluded that the compressive strength of concrete increased at the age of 7 to 28 days but the results at the age of 28 days did not reach 100%. The iron reinforced beam at the age of 7 days reached 26 KN, at the age of 14 days reached 30 KN and at the age of 28 days reached 33 KN. Where it can be concluded that the compressive strength of concrete increased at the age of 7 to 28 days. Based on the results of the study, it was found that the beam with the addition of bamboo and iron reinforcement experienced an increase in the percentage of flexural strength testing while the beam reinforced with bagasse at the age of 28 days did not reach the desired target.

Abstract

This study evaluates the use of iron powder waste as a partial replacement of fine aggregate in concrete to reduce environmental impacts. By testing various percentages of iron powder (0%, 7.5%, and 12.5%), this study analyzed the compressive strength of concrete at the ages of 7, 14, and 28 days. The results showed that the addition of iron powder tended to reduce the compressive strength of concrete compared to normal concrete. Concrete with 7.5% iron powder had better compressive strength compared to 12.5%, but both had not reached the expected compressive strength. Further research is needed to find the optimal combination of iron powder and other additional materials.

Abstract

Although concrete is less strong in resisting tensile loads, the addition of fibers makes it a more resilient construction material, especially fiber concrete which is abrasion resistant and has better tensile, flexural and compressive strengths. In Indonesia, coconut fibers, which have been used since prehistory as a building material, are now being utilized as an additive in cement, thanks to their advantages in absorbing water and having good tensile strength. The use of coconut fibers not only increases the flexibility and strength of concrete, but also utilizes household waste that is difficult to recycle to create high-quality construction materials that are more durable and less prone to cracking. The results of testing the compressive strength of normal concrete at 28 days showed that without coconut fiber waste, the compressive strength was 440 kN (f´c 24.91 Mpa). With the addition of 5% coconut fibers, the compressive strength dropped to 318 kN (f´c 18 Mpa), and with 10% coconut fibers, to 292 kN (f´c 16.53 Mpa), showing the effect of fibers on the mechanical properties of concrete.
