Partial Replacement of Cement with Burnt Rice Husk Ash for Low Strength Concrete Production.
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 3
Abstract
Nigeria, one of the leading African countries in economy makes use of sandcrete blocks and concrete for various types of structure in the construction industry. Thereby making cement expensive and unaffordable for many in the country. Rice Husk Ash (RHA) which is in abundance in the country can be substituted for cement in making sandcrete blocks and low strength concrete for construction. Investigations showed that inclusion of RHA in the production ofsandcrete blocks yields averagely and comparative strength with that 100% cement .Sorptivity and permeability were also observed to have increased with increase in RHA content. The highest compressive strength for concrete was attained at a percentage RHA content of 10 percent. Results also suggested that RHA as a substitute can act as an insulator in houses. If well optimized, RHA will serve as an alternative to OPC in the construction industry leading to the production of low density sandcrete blocks that cost less, concrete with a durable strength for construction of low income housing and also improve waste handling.
