| Summary: |
The use of rubber crumb has been introduced in the production of concrete. This
alternative is found out to be a great choice in order to significantly reduce the
amount of scrap tire disposed in a landfill area. This is because the production of
concrete annually could reach up to 500 million tonnes. However, crumb rubber
considerably reduced the mechanical strength of concrete, which are compressive,
tensile, and flexural strength. Thus, several materials are inserted in the design mix to
improve its strength, such as, nano silica, fly ash, and superplastisizer. In this study,
firstly, 30 trial mixes of Grade 40 are developed through Respond (RSM) software.
Each mix consists of 6 cube samples with the size of 100 x 100 mm. Compressive
strength test is done on the samples at 14th day and 28th day. Then, the results are
analyzed to come up with the optimum mix design of the rubbercrete. Next, by using
the optimum mix design, five mixes of different grade is used for direct tensile test
and flexural test. Six samples of each mix design would be produced in the shape of
dog-bone and tested for tensile strength of the concrete. |
