Abstract

Needs are increasing bricks and soil damage caused by the brick kiln to be a problem in the field that should be addressed immediately. As an alternative to adobe bricks for the manufacture of wall is expected to overcome these problems. One of the alternatives that will be used to solve the problem is brick with added material rice husk. That is to do the mixing of rice husks in brick-making. The goal is to determine water absorption (absorption) bricks have been mixed rice husk.The study design used is an experimental method which is the research methods used to find the effect of treatment (treatment) specific. The study design is intended to determine the effect of the use of rice husk as an added ingredient in the manufacture of lightweight concrete blocks that in the review of water absorption. The composition is used between sand, Portland cement and water with a ratio of 1 PC: 5 PS. Lightweight concrete blocks were created and tested with a mixture of 0%, 20% and 40% with a reduction of sand. Results of testing water absorption, light brick can average the normal brick 0% 18%, 20% of 15% and 40% of 11,88% at 28 days of age adobe. Based on the results of research and discussion that has been described previously, it can be concluded. The addition of rice husks in brick making brick produced has a water absorption value decreases.
