Estimate the Compressive and Flexural Strength Test of Natural and Recycle Concrete Aggregate

Abstract

Rapid industrial development causes depletion of natural aggregates, creates a huge amount of waste materials from constructional activities. To utilize recycle concrete aggregates in the production of concrete to reduce such problems. Use of recycle concrete aggregate in concrete is economical and environmentally viable. The main concern of this research is to reuse the demolished concrete as coarse aggregate for building a new structure. For this reason, the compressive strength as well as the flexural strength of natural concrete aggregate was compared with recycled concrete aggregate at different curing period. Also, the strength of mixed concrete (NRC) which contains half natural concrete aggregate and half recycles concrete aggregate was determined. Concrete made for recycle aggregate has both enough flexural strength and compressive strength. The 28 days compressive strength and flexural strength of recycle concrete were found 1975 psi and 676 psi respectively.
