Abstract
One of the development of concrete technology in construction’s world is Self-Compacting Concrete. Self-Compacting Concrete (SCC) is an innovative concrete that able to “flow” and condensed by gravity and its own weight with little vibration or even without a vibration device at all. However, these concrete still have deficiencies like general concrete that is weak to tensile. To increase the tensile strength of the concrete is by adding fiber into the mix. One type of fiber that can be used as an additive to the mix is Polypropylene fibers. This study aims to determine the effect of adding polypropylene fibers to the mechanical properties and characteristics of SCC concrete and to know the optimal polypropylene fiber content in the manufacture of Self Compacting Concrete. Fiber addition variations are 0 kg / m3; 0.25 kg / m3; 0.5 kg / m3 and 0.75 kg / m3. The result of the research showed that the variation of 0.5 kg / m3 and 0.75 kg / m3 addition of fibers didn’t fulfill the requirements to be categorized as a SCC concrete. The results of hard concrete test showed the highest compressive strength that is on the SCC PP concrete of 22.31 MPa at the age of 1 day and 46.24 at the age of 28 days. The highest strength is on the SCC 0.25 PP concrete of 6.52 MPa at the age of 1 day and 10.07 at the age of 28 days. The highest flexural strength is on the SCC 0.25 PP concrete of 6.76 at the age of 1 day and 8.60 at the age of 28 days.
Highlights
Improper quality control in the field has been a problem with the quality of concrete in the world of concrete construction today
Concrete mixture of 0.50 PP Self-Compacting Concrete (SCC) and 0.75 PP SCC cannot be categorized as Self Compacting Concrete because it does not meet all the criteria of Filling Ability, Passing Ability and Segregation Resistance Ability
Test results of concrete compressive strength indicate as the addition of polypropylene fiber on SCC concrete is decrease the value of concrete compressive strength
Summary
Improper quality control in the field has been a problem with the quality of concrete in the world of concrete construction today. A poorly vibrated compaction process can cause bleeding and segregation of concrete [8]. As a result, it will create air cavities in the concrete that can reduce the durability of the concrete. In the late 1980s, Japanese researchers developed self-compacting concrete known as SCC [1] as a solution to the problem. SSC (Self-Compacting Concrete) is a very plastic fresh concrete that can flow with its own weight and solidify without the aid of a vibrator. The researchers sought to improve the weakness by adding fiber to fresh concrete that is expected to reinforce the concrete and spread evenly to prevent early concrete cracks in the early hydration or loading period
