DE QUIROS, MYLA D. and OCBIAN, JUVILYN V. Use of Crushed Glass Bottles as Coarse Aggregate for Concrete Mixture with Superplasticizer. Undergraduate Thesis. Bachelor of Science in Civil Engineering. Cavite State University, Indang, Cavite. May 2017. Adviser: Engr. Roslyn P. Pena. The study was conducted to produce recycled glass bottles as coarse aggregate for concrete mixture with superplasticizer, determine the compressive strength at 7th 1 4d1 , and 28 th days curing, determine the optimum mix ratio, and compare the cost of the commercial concrete mixture to the cost of using crushed glass bottles as coarse aggregate for concrete mixture with superplasticizer. The study took place at Cavite State University-Main, Halang Amadeo, and Cavite Testing Center, Tanza Cavite from September 2016 to March 2017 under the supervision of Engr. Roslyn P. Pena Tests were conducted to determine the effectiveness of the use of crushed glass bottles as coarse aggregate in concrete mixture with superplasticizer. These tests were unit weight determination, slump test, and compressive test. The results were also investigated using the Analysis of Variance (ANOVA). The Duncan Multiple Range Test was also used to analyze the mean analysis. The mass density and compressive strength were analyzed independently using the 7th 1 4th 28th day. The optimum mix ratio is 75 percent gravel and 25 percent crushed glass bottles. The study clearly concludes that the most economical mixture was still the treatment that used 100 percent gravel a 0 percent crushed glass bottles. If the recycled glass bottles are free, the production cost per cubic meter and per trial mix are cheaper compared to using coarse aggregates. The experimental results show that with increasing crushed glass bottles, the compressive strength decreases. Crushed glass bottles can be used for path walks, sidewalks, catch basins and any structure resting on the ground.
