FEATI UNIVERSITY-CIVIL ENGINEERING DEPARTMENT THESIS AND RESEARCH 2007

ABSTRACT
Title : “RECYCLED BROKEN GLASS AS SUBSTITUTE FOR COARSE
AGGREGATE TOWARDS DESIGNING A CONCRETE
MIXTURE"

Researchers : MELBORNE M. BOSTON, FELIX B. CERDA and RICHARD S. USI

Adviser : Prof. Gerard V. Paguibitan

School : FEATI University

Date : March 2007

Degree : Bachelor of Science in Civil Engineering

The Philippine today is on the front line of pursuing its economical, social and political, programs. Parallel to these matters, the national consciousness of the individual must be strengthening.
Rejected broken glass a substitute for coarse aggregates by percentage is capable of strengthening and infusing this equipment among the student to pursue doing some experiment to discover new materials in mixing concrete and also lessen the wastage of glass, instead of throwing it into the garbage we can used it as a materials in concrete mixing.
However the purpose of this study is to describe potential of glass in terms of strengthening concrete structures and to minimize the percent amount of gravel used in the construction. This study describes some important uses to consider and develops a model for cost estimating.
The value of substituting recycled glass for low price virgin raw materials in container manufacturing has always placed in an upper limit on the value of collected recycled glass. Increasing, however, a researcher is being performed to asses that availability of processing glass to gravel size for marketing as a raw materials in traditional industrial materials application.

SUMMARY OF FINDINGS
Based upon the results of the compressive test, the broken glass aggregate gradually diminished as the percentage of the broken glass increases. A five (5) percent inclusion of broken glass to the concrete mixture gives a compressive strength that complies with the standard compressive strength for wall panel and gives a higher compressive strength than the sample concrete without broken glass.
The laboratory trial batches are used as the basis for selecting concrete proportion and compressive strength test are made in accordance with Method of Tests of Compressive Strength Tests (ASTM C-39 93a) on cylinders prepared in accordance with method of making curing tests specimen in the laboratory (ASTM C-192 93a).
The findings showed that broken glass can be use more than 15% weight of coarse aggregates in preparation in concrete mixes.


CONCLUSION
Alternative materials referred to, as a broken glass can be use 10% weight of coarse aggregates in preparation in concrete mixes. This showed that the required compressive strength satisfied as indicated on the tests results from DPWH-NCR.
The effect of broken glass to the concrete mixture is that an increase of more than five percent insertion by weight to the concrete mixture compromises the compressive strength of the concrete. Therefore a mix design of five percent weight insertion to the concrete mixture gives a desirable result in terms of its compressive strength.


RECOMMENDATION
Based on the stated conclusions, the researchers propose the following recommendations:
1. A derivation of equations on the flexural and compressive strength using different
types of broken glass mixture.

2. A testing of more concrete specimens with broken glass specimen and plain concrete
to achieve ideal good results.

3. Provide an apparatus that will break down the glasses to a desirable concrete mix
size
