ABSTRACT Waste is a problem that never ends when discussed. Indonesia itself is listed as the second largest waste producing country in the world after China. This is proven by the increase in the amount of waste in Indonesia by 0.8 million tons from 67 million tons in 2019 to 67.8 million tons in 2020. To overcome this waste problem, the best solution is needed, such as creating a classificat…
ABSTRACT Concrete in a seawater environment is prone to damage due to the high salt content in seawater. Seawater intrusion causes salt crystallization in concrete pores. tidal conditions resulting in wet-dry cycles on the structure accelerate the crystallization process. Therefore, the characteristics of concrete will be studied using shell powder and silica fume as a substitute for cement to…
ABSTRACT Formaldehyde is the simplest aldehyde in terms of chemical structure. At room temperature, formaldehyde is a colorless gas with a pungent odor.
