Study Of Paper Waste Based Paving Blocks On Compressive Stregth And Water Absorption

As one of the products of the development of construction materials technology, paving blocks function for cover material and surface hardening that are very widely used for various purposes, ranging from simple needs to uses that require special specifications. In addition, now also the need for high quality but environmentally friendly building materials has become a demand given the large amount of waste that has not been optimally utilized. In this study, paper waste will be used as a subtle aggregate substitute material in the manufacture of paving blocks which are expected not only to provide alternative paving blocks that are environmentally friendly but also fulfill the required conditions where the use of waste paper-based paving blocks is intended as pavement on the archipelago considering the price and access to resources are quite expensive and the difficulty of bringing heavy equipment to the locations of islands is that most of them only have ports or docks whose capacity can only accommodate fishing boats. Other things obtained also when using building materials that have lighter weight can result in reduced weight of the construction material so that it is easier for transportation. Making test specimens is carried out by varying the composition of paper waste against fine aggregates of 0%, 2.5%, 5%, 7.5%, 10%, 12.5%. Test specimens were prepared for compressive strength testing by testing samples at 7 days, 14 days and 28 days. While the specimens for testing the absorption of water at the age of the block paving reached 28 days. Based on the results of testing using paper waste shows that the waste can be reused as a mixture of paving blocks so that it can optimize the use of waste but also as an effort to recycle waste into a product that provides higher economic value. 
