ATAS, JOHN DENVER P. and BAUTISTA, PERKIN M. Reclaimed Gravel from Crushed Concrete Cylinders as Supplementary Coarse Aggregate for Concrete. Undergraduate Thesis. Bachelor of Science in Civil Engineering. Cavite State University. Lndang, Cavite. May 2017. Adviser: Engr. Cene M. Bago.<br/>The study entitled Reclaimed Gravel from Crushed Concrete Cylinders as Supplementary Coarse Aggregate for Concrete was conducted at the Materials and Testing Laboratory of the Department of Civil Engineering, Cavite State University, Indang, Cavite from August 2016 to May 2017. The study aimed to determine the strength of concrete using reclaimed gravel from crushed concrete cylinders as supplementary coarse aggregate for concrete, of what proportion would it produce the highest quality of concrete and what would be the compressive strength after 8, 15 and 29 days of curing.<br/>The concrete cylinders, which were the sources of reclaimed gravels, were donated by the Associated Services and Testing Center — Cavite (AS TEC). Gravels were reclaimed by crushing the concrete cylinders and were sieved to a maximum size of 3/4" Five treatments were used in this study. The commercial gravel was substituted by 60% on Treatment l, 50 % on Treatment 2, 40% on Treatment 3 and 100% on Treatment 4.<br/>Treatment 5 was not substituted by reclaimed gravel to serve as control.<br/>After the tests for the unit weight, specific gravity and absorption of the coarse aggregates were conducted, the results showed that the properties of the reclaimed gravel are not significantly different from those that are commercially produced.<br/>All of the specimens were tested after the specified 8 th 15th and 29th curing days. The compressive strength tests of all the specimens were determined and the results<br/><br/>showed that the Treatment 5, the mixture with no substitution of reclaimed gravel attained the highest strength. For the mixtures that were substituted by reclaimed gravel, the Treatment 3, with 40% reclaimed gravel, achieved the highest strength.<br/>The data were also analyzed using the Analysis of Variance (ANOVA) and Duncan's Multiple Range Test (DMRT) was used in the comparison among mean analysis.<br/>The results of the study indicated that as the amount of the reclaimed gravel increases, the compressive strength of the sample decreases.<br/>In terms of cost, even if the estimated cost of producing concrete with partial substitution of reclaimed gravel is lower than the commercially formed, it still remained not to be economically viable due to the inconveniences, such as great amount of time and effort that was to be exerted in reclaiming the gravel and because it did not improve the compressive strength of the concrete.<br/>The study determined that the concrete produced with the reclaimed gravel was considered as low-strength concrete and can be used for single storey houses and free-standing walls or for foundation walls and slabs, walks, patios, steps and stairs as provided by the International Building Code.<br/>The researchers recommend making sure that the size of the aggregates was uniform since it affects the strength of concrete, to devise a crushing machine that will efficiently crush the concrete cylinders and sort the gravels and try to follow the mix design of ASTM or ACI Code.<br/> |
