Abstract/Summary
The objective of this study is to test and develop crushed concrete to substitute gravel for concreting purposes. In order to meet this objective, the researchers have developed and performed two (2) experiments so designed such that when supplemented by selected readings, research, and acquired knowledge, they could arrive at a credible and reliable conclusion. They will be able to give factors that would contribute to loss or gain in compressive strength of the recycled concrete as compared to normal concrete. From these factors, they will also be able to formulate ways to develop crushed concrete to give a greater compressive strength for recycled concrete.The first experiment takes into consideration that the fine particles brought about by the crushing of concrete contain cementitious particles that have not yet hydrated with water and would therefore contribute in strength. The second experiment, however, discarded the fine particles with the assumption that its presence only increases the cement requirement due to the increase of surface area.From the analysis of data and interpretation of test results, the researchers have concluded that the methods and procedures done in Experiment No. 2 are more effective and produced better results than those of Experiment No. 1. The results of Experiment No. 2 are better such that the compressive strength of the recycled concrete increased by 2 percent as compared to the decrease of 81 percent obtained in Experiment No. 1
