Improved Quality Lightweight Concrete Active Pozzoland Waste Tile As Filler With 900°C Fuel Temperature

Abstract

The earthquake is a serious threat in the field of construction in archipelagic countries like Indonesia. The heavier the building is, the greater the earthquake force produced. Lightweight concrete is a concrete that has a light density and contains lightweight aggregate. According to SNI-03-3449-2002 lightweight concrete has a weight of not more than 1850 kg / m3. The innovations used are not limited to the addition of aluminum powder additives but also the utilization of waste as a concrete material as an alternative in waste utilization. The result of the addition of tile powder used as filler in each variation can not increase the value of compressive strength but all the result of the test object still meet the criteria of light concrete that is under 1850 kg / m3. The increase in compressive strength occurs in variations 3 and 5 but does not exceed variation 1. In the 5x5 cm paste specimen, the material is mixed without the use of aluminum powder, the results are more optimal, the data obtained is more accurate, this is due to the method of making pasta with only cement and tile dust no material is wasted.
