Perbandingan Kuat Tekan Paving Block Ramah Lingkungan Berbasis Limbah Botol Plastik Kemasan Air Mineral dengan Limbah Cangkang Kerang dan Limbah Botol Kaca Sebagai Bahan Subsitusi Terhadap Semen

Among various kinds of alternative building material products used as cover or hardening of soil surface,
Paving blocks are products that are in great demand by consumers. As a covering material and ground
surface hardening, Paving blocks are widely used for various purposes, ranging from hardening and
beautifying road sidewalks, road hardening, hardening of parking areas, and can even be used in special
areas such as container ports and airports. This is because Paving blocks have advantages from other
products in terms of shape, size, color and style. In addition, Paving blocks can be combined with other
cover materials. Considering the use of Paving blocks that are quite extensive, it is necessary to have
alternative substitute materials that can reduce the use of natural materials due to increased physical
infrastructure development but are environmentally friendly. One of the eco-friendly Paving block
alternatives is by utilizing plastic bottle waste packaging as mineral water as sand substitution material
as well as green seashell waste and glass bottle waste as cement substitution material in making Paving
blocks. In this study samples were made by comparing the composition of plastic bottle waste packaging
of mineral water, seashell waste and glass bottle waste with 0%, 5%, 10%, 15% and 20% substitution
treatment of the dry weight of Paving blocks. The test results showed that the optimum mixture variation
was found in a mixture with a variation of 10% of plastic bottle waste packaging of mineral water + 10%
of seashell waste with a compressive strength of 12.8 MPa and a percentage of water absorption at 28
days of 2.63%. Where the results of the variations in Paving blocks are categorized into quality C which
can be used for pedestrians.
