| Title |
A Study on the Demolition and Reuse of Reinforced Concrete Building |
| Abstract |
This study is the test result on concrete compressive strength using natural gravels and recycled gravels. The recycling concrete was made with natural sand and recycled gravel from crushed concrete. The results of test are as follows;1.The compressive strengths of recycled concrete (Fc<=210kg/cm2) made with more than 50% recycled gravels are 8-9% less than the strength of concrete using natural aggregates (say natural concrete).2.The compressive strengths of recyled concrete (Fc>=240kg/cm2) made with 100% recycled gravels are 28.3% less than the strength of natural concrete. |
