Pembuatan Mortar Polimer Nanokomposit Sebagai Bahan Perbaikan

Construction in the field can often be encountered with various problems, one of which is damage to concrete structures or non-concrete that affect weakening a structure. Many developed countries have carried out polymer mortar development efforts. Until now, still ongoing reduce use cement and anticipate global warming. One them by utilizing as an adhesive substitute for so strong produced shorter time. This research combines 40%-55% epoxy resin hardener, 40% fine aggregate, 5%-20% Fly Ash 1%-5% nanosilica. The results obtained show initial bond setting time 70 minutes final 110 minutes. result faster than normal mortar. more used, longer bonding For Compressive strength test maximum Theobtained were results62 MPh mixture 38% aggregate fine, 20% fly ash 2% specific gravity, 1,760 Kg/M3. Aggregates grains produce higher mechanical fillers coupled nanosilica increase strength, used , nanocomposite material increases appoint critical then decreases.  Keywords: Polymer Concrete, Nanocomposites
