【 摘 要 】

The research concerns the strength of lightweight concrete with aluminum fiber as micro-reinforcement by environmental load especially burning and water curing. In this cylindrical research concrete of 150 mm dia, 300 mm high for the compressive test. Fibre volume fraction are 0,75% of concrete. Aluminum fiber with aspect ratio 50, cement type I, sand, always, water, and discrete are used. Testing is based on SK SNI M 14 1989 F. The result shows that increasing self-recovery of the average compressive strength of cylindrical concrete is 121.30% and 109.55% on lightweight concrete and aluminum fiber lightweight concrete with water curing for 56 days. Water curing can self-healing lightweight concrete and aluminum fiber lightweight concrete after burning.
