Abstract

The Concrete starts use material substitution for reduce its brittle character. The Material substitution is substance that can change concrete which are coarse aggregate, fine aggregate, and cement with others materials, such as the portland cement combine the steel slag, broken stone (coarse aggregate) with pumice stone, etc. The one of function from concrete material substitution method can exercise industrial waste. The industrial waste can be an output of residue production from industry activities, one of which is clinker (the waste of burning coals).
The purpose of research are 1)Measure of the concrete compressive strength value between Destructive Test dan Non-Destructive Test method on lightweight concrete with clinker as coarse aggregate replacements; 2)analyze the correlation of time variation on increased value of compressive strength of lightweight concrete which is tested by UTM, the hammer test, and UPV; 3) the lightweight concrete design with clinker on optimum strength for structural functions and building construction.
The result of this research is to know precisely the compressive strength of lightweight concrete made from Clinker which have been tested by UTM, Hammer Test, and UPV. It provides an evaluation of the structures and building construction feasibility towards existing building as an effort to create buildings that are responsive and resistant to natural disasters.
