Tinjauan Momen Lentur Pelat Lantai Precast Beton Ringan Menggunakan Bahan Campur Limbah Plastik Dan Pecahan Genteng Diperkuat Tulangan Wiremesh

Floor plates are one of the structural components of construction both in buildings and bridges and are usually constructed with reinforced concrete construction. In general, the manufacture of reinforced concrete slabs is done by casting in place, so it will require more power and time in the process. The precast floor plate itself is the unity of several blocks of concrete plates that can be arranged in such a way that it can make a better quality floor plate. The precast floor plate is also one of the precast concrete results. Materials used in the manufacture of precast floor plates are water, cement, tile shards, HDPE plastic waste (High density polyethyleneI), sand and reinforced with wiremesh reinforcement. The purpose of this study is to create new innovations from precast floor plates in order to be more efficient and practical, both in terms of economy and time of workmanship. Planning of this precast floor plate uses mortar with a fine aggregate ratio and 1: 5 cement, and f.a.s 0.5. Test specimens made in this study as many as 12 pieces of concrete cylinders with a diameter of 15 cm and a height of 30 cm. With details of 3 pieces of concrete cylinders test object without mixed waste material plastic and 9 pieces of concrete cylindrical test object with a mixture of plastic waste material. The precast floor plate is made with the size of 110 cm x 50 cm as many as 12 pieces. With details of 3 pieces of specimens without waste plastic mixtures and 9 pieces of specimens with a mixture of waste plastic materials. This precast floor plate study tests the compressive strength and flexural strength. The result of concrete strength test of concrete cylinder with mixture material of plastic waste 0%, 4%, 6%, 8% obtained result respectively 16,135 MPa, 4,133 MPa, 3,831MPa, 3,416 MPa. The precast floor plates with flexible strength testing with plastic waste mixed materials of 0%, 4%, 6%, 8% obtained respectively 1492604,17 N.mm, 1369375,00 N.mm, 1191979,17 N.mm, 1018125,00 N.mm
