The Influence of Fly Ash and Aggregates Composition on Pervious Concrete Characteristics

Abstract:

Fly ash as a pozzolanic waste material can be utilized to substitute part of Portland cement in concrete mixture. The concrete paving industry utilizes the fly ash up to 50% (by weight) of the total binder. This study aims to obtain the characteristics of fly ash applications for pervious concrete. The composition of the binder developed based on the optimal proportion of fly ash from the previous study and the maximum of fly ash percentage used by the local paving industry in general. Other mix variations were made of the same binder composition with the addition of 6% of fine aggregates. The compressive strength of pervious concrete which binder composed of 63% portland cemet composite-25% fly ash-12% silica fume gained at 28 days, was not much different from the compressive strength of the pervious concrete without fine aggregate and with the binder composition of 50% FA-50% PCC and 0% SF. The value of the compressive strength test of the pervious concrete without fine aggregate is still within the range of compressive strength values ​​according to the ACI 522 R-10. The permeability rate of the pervious concrete is in the range of permeability research result of Chopra, 2013 (0.97 ÷ 1.90 cm/sec), but still higher compared to permeability rate gained by Dewoolkar, 2009 (0.83 ÷ 0.98 cm/sec).
