Abstract
The research concerns on strenght of light weight concrete with aluminium fibre as micro-reinforcement by enviromental load especially burning and water curing.
In this research cylindrical concrete of 150 mm dia, 300 mm high for compressive test. Fibre volume fraction are 0,75% of concrete. Aluminium fibre with aspect ratio 50, cement type I, sand, alwa, water, and viscocrete are used. Testing are based on SK SNI M14 1989 F.
The result shows that increasing self recovery of average compressive strenght of cylidrical concrete is 121.30% and 109.55% on light weight concrete and aluminium fibre light weight concrete with water curing for 56 days. Increasing self recovery of average MOE is 118.97 % and 105.01 % on light weight concrete and aluminium fibre light weight concrete with water curing for 56 days.
Water curing can self healing light weight concrete and aluminium fibre light weight concrete after burning.
