3. OBJECTIVE
• Produce a model of interlocking concrete using concrete wasted from the
ruins of old buildings
• Make experimental on Reccon ineterlocking use sieve analysis,
compression and skid resistance test.
• Compare price of interlocking concrete and reccon interlocking
4. PROBLEM STATEMENT
• Waste concrete not handle efficiently
• Impact on the environment
• Disposal area increased
5. SCOP
• Use for light load
• Example pedestrian and reacreation
• Consist Waste concrete from construction

15. COMPRESSION TEST
• Determine Net ratio and maximum strength
• Prepare cube for 7, 14, and 28 days.
• Each sample consist of 50%, 80% and 100% of waste concrete

20. SKID RESISTANCE
• Determine resistance on surface of reccon interlocking
• Provide comfortable walkway
• Differentiate resistance on surface between reccon interlocking, slab and
Asphalt.
• Condition and type of surface was manipulated.
