Abstract
Concrete is being used a lot in construction. Concrete is made from aggregate, water and cement. The characteristic of wet concrete is that, it is wet and hard and very much depend on the ratio of water-cement and also the texture of aggregate. Due to that, other materials also used to be find as an alternative. The aim of this research is that to find out whether the palm ash can be used as alternative to concrete. Portland cement, aggregate, water and palm ash are used in this research. The palm ashes is an industrial as waste that was no commercial value, except for it is used as composite fertilizer. This research is carried out to compare the palm ash concrete and cement. The research that has been carried out are the cube density, the velocity of ultrasonic PUNDIT, the strength of compression, flexural strength, and the ratio water absorption to cement is 0.57 for sample concrete. The sample curing will take 3,7,14,28 and up to 90 days sometime in the plain water. From research, we fixed out that the palm a,sh can be used as cement replacement. The palm ash can given exactly the same compression strength like cement.
