Properties of Normal and Recycled Brick Aggregates for Production of Medium Range (25–30 MPa) Structural Strength Concrete

摘要: This study compares the properties of normal and recycled brick aggregates to produce a medium range (25–30 MPa) compressive strength structural grade concrete. Up date, are commonly used in concrete some South Asian African countries. Many structures which were built last century made from them already position ending their service life. At same time, population economic growth is forcing demolition many old structures. Therefore, there huge flow construction waste thereby it necessary recycle overcome problem occupying landfill sites. For this study, collected various demolished building sites physical mechanical performance then compared with aggregates. It found that comparable aggregate at level. The production cost also be 10–12% lower than
