Daftar Isi:
- This study aimed to determine effect of water absorption in the concrete mix with rice husk ash and boiler ash palm on the ideal composition of on concrete porosity. The research method is done by adding the mixing rice husk ash and boiler ash palm oil on composition (5%, 10%, 15%, and 20%) and soaking in the period (7 days, 14 days, 21 days, 28 days, and 60 days) in the sample preparation and testing of samples (water absorption and variable regression analysis of the porosity of the concrete to immersion) and of the best composition of the XRD analysis. From the results obtained by the addition of a mixture (Rice Husk Ash, Boyler Ash Palm Oil, and both of them) on a concrete base is the addition of the composition of the mixture of 5%. This suggests that the presence of the concrete mixing resulting SiO2 content in the concrete is reduced and by the addition of a significant SiO2 content approaches the SiO2 content in the concrete is the mixture Rice Husk Ash 5%. The concrete with a mixture of 5% rice husk ash had been a low water absorption which are supposed to improve the quality of concrete. Relationship variables showed a relationship is negative in addition to the concrete mixture to produce water absorption.
