A Study on Properties of Paver Blocks Manufactured Using Different Percentage of Recycled Aggregates With Partial Replacement of Cement By Fly Ash”
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 1
Abstract
The increasing difficulty in securing natural coarse for the production of concrete coupled with the environmental issues and social costs of unlimited extraction of natural aggregates makes the usage of recycled aggregate concrete (RCA) in the construction industry of prime importance. Now a days, awareness of use of recycled aggregate as a construction material is gaining importance around the world. An attempt is made to use this recycled aggregate as a material replacing coarse aggregates in paver blocks. The properties of RCA namely specific gravity, particle size distribution, water absorption, moisture content ,impact value, crushing value, flakiness and elongation index are studied. As per the norms of IS 15658-2006 code, required samples of paver blocks of each type are casted and tested for compression, tensile, flexure and abrasion values. Changes in the properties of paver blocks with increasing RCA percentage with partial replacement of cement by fly ash (10% by weight of cement) are analyzed extensively. Conclusions regarding optimum use of RCA, ecological and economic benefits of RCA replacing conventional coarse aggregates are drawn.
