A Comparative study on the compressive strength of concrete using recycled ceramic tiles as coarse and fine aggregate versus concrete using conventional aggregate
- Cebu City CIT-U 2014
This study is focused on the compressive strength of concrete with ceramic tile aggregates as replacement for conventional coarse and fine aggregates. This study also covered the comparison of strength between the conventional concrete and the concrete with ceramic tile aggregates. The waste ceramic tiles used in this study were obtained from hardware stores in Metro Cebu. Also, other materials used in this study were locally available. Ceramic tile is a common building material; it is used for covering floors and walls, and can also be used as roofing material. This study aimed to recycle this material by using it as an aggregate for concrete. An experiment was done to find the suitability of ceramic tile as aggregate for concrete by comparing the strength of concrete with ceramic tile to concrete with natural aggregates. Properties of the aggregates such as water absorption, weight, bulk density and specific gravity were derived. Two kinds of samples were made in two batches. Three (3) cylindrical samples of concrete with ceramic tiles as aggregates and another three (3) samples for conventional concrete were made per batch. The samples were cured for 28 days. After curing, the samples were tested to determine their compressive strength. The results showed that the compressive strength of concrete with ceramic tile aggregates is higher than that of the concrete with natural aggregates by 2-4%. The researchers therefore concluded that there is no significant difference in compressive strength between concrete with ceramic tile aggregates and concrete with conventional aggregates. The researchers recommended the use of concrete with ceramic tile aggregates on non-critical structural members (e.g. stiffener columns and lintel beams) and those concreting works which are not exposed to moisture. The researchers also recommend that additional studies relating to different ratios, curing duration, and economical studies be made in the near future.
