Analisa Penggunaan Foam Agent sebagai Bahan Dasar Pembuatan Bata Ringan

Abstract

Research conducted on lightweight brick is one of the things that need to be developed and researched further. But in studies need for election materials to be used, because the light brick research relies heavily on the selection of appropriate materials. Light brick produced must also comply with the requirements, technical specifications and durability, its use in construction and also environmentally friendly. This study aims to present materials that can be used in the manufacture of lightweight brick, and with different variations and also examines the characteristics of light brick. Researchers used a standard variation presented Neopor which is then used as a reference mix-design and the addition of a mixture of 30% for sample 2 and 60% for 3 samples. In this study, the authors use a foaming agent material in the concrete mixture that will make the concrete lighter. This can be seen in the manufacture of lightweight brick cube specimen. On the composition of cement: sand: foam: water 1: 1.25: 0.004: 0.53 generate an average compressive strength of 14.254 kg / cm2 with an average weight of 2.5102 kg; On the composition of cement: sand: foam: water of 1.3: 1.625: 0.0052: 0.689 generate an average compressive strength of 10.21 kg / cm2 with an average weight of 2,213 kg; On the composition of cement: sand: foam: water of 1.6: 2.0: 0.0064: 0.84 resulted in an average compressive strength of 14.254 kg / cm2 with an average weight of 2,079 kg. By this research the author can produced brick light that can meet the standards of the compressive strength of the referenced according tjokrodimuljo that the density value of 240-800 kg / m3 light brick compressive strength ranges from 0.35 to 7 MPa (3,569- 71 kg / cm2).
