Abstract
Coconut Shell actived Nanocarbon to Lightweight Concrete have done. LWC mixture of CS actived nanocarbon fillers made by mixing PPC cement, sand, broken stone, coconut shell actived nanocarbon fillers and water in various proportions. The ratio of CS actived nanocarbon on filler used ( x = 0%, 5%, 10%, and 15%), with the aim of getting a different level of compressive strength testing. The particle size of activated CS carbon using the high temperature physical activation method 800C and chemistry (immersion of ZnCl2 solution) has an average diameter of 4,842.8 nm. The SEM shows that high porosity occurs and the shape is not homogeneous. EDS analysis to determine the composition of the elements in the sample is known that the CS activated carbon samples have a maximum value in the element Carbon, Oxygen. The sample of CS actived Nanocarbon to LWC x= 0% ,the results of the maximum value of % mass and % atom are the elements Oxygen, Carbon, and Calcium. For x = 10% the maximum value are the elements Oxygen, Carbon, and Silicon. The value of the strength of the objects in the CS activated carbon filler concrete sample (x= 5%) has maximum strength value 12.9 Mpa
