THE CHARACTERISTIC OF NON SAND CONCRETE BRICK BY ROOF-TILE-FRACTION AS CARSE AGGREGATE (Study foccused to : quality, shape, and production cost)

Abstract

Nowdays, the number of resident building and public facilities project is increasing rapidly. So, the demand of building materials is increasing too. One of building materials is brick. Then, there are some efforts to find other building materials for substituting brick (for example: bataco). Roof tile fraction can exploited as coarse aggregate for non sand concrete brick (called batanes). This research will explore the characteristic of batanes. This research proposed five types of PC:RTF of batanes, there was 1:12; 1:10; 1:9; 1:8; 1:7; 1:6. All of types used WCF (Water Cement Ratio) 0,4. For collecting data, researcher used documentation, observation and test, by appling several instruments there was: counter weight, Compression Test Machine (CTM) and observation form. Data was analysed by diskriptif statistic. This research carry out several conclusions. The quality of batanes was 50% uper than bataco. The production cost of batanes (with has PC:RTF 1:9 - 1:12) was 10% cheaper than bataco production cost. According to environmental aspect, batanes have a positive value because exploit roof-tile industry waste. The non favourable value of batanes was according to both weight and shape aspect. The weight of batanes was 27% heavier than bataco, and the surface of batanes has some holes.
