Experimental study investigation of rice husk ash on concrete
Abstract
The research investigation, effect of Rice Husk Ash on Concrete performed on laboratory scale, in which the (OPC) cement has been replaced by RHA with in terms of percentage by weight such as 12.5% and 25% of cement for 0.45 water/cement ratio. The laboratory analysis proved the compressive strength at 12.5% replacement of cement with RHA. This is the minimum content of RHA gives the better results in this study. Many of the analysis tests were performed such as, Standard consistency test, setting time test, soundness test, workability test and compressive strength test. This test proves the similarity of results obtained with the same laboratory conditions with OPC. The results were compared to controlled sample and the viability of adding RHA to concrete was verified. The minimum RHA content has been used as a pozzolanic material in cement and concrete. RHA provides several advantages, such as strength and durability properties, and environmental benefits related to the disposal of waste materials and to reduced carbon dioxide emissions. The use of RHA cement concrete improved stability reduced the heat generation and shrinkage. It strengthens transition zone i.e modifying the pore structure in the hydrated cement paste.
