HIGHLIGHTS

  • Compressive strength of SCC made with stone chips and brick chips as coarse aggregate is studied.
  • Compressive strength of SCC for different mixed ratios at different ages of concrete is obtained.
  • Average slump flow value of SCC made with stone chips is higher than brick chips.
  • Compressive strength of SCC made with stone chips is higher than brick chips.
  • Stone chips are highly recommended to use as coarse aggregate in SCC.

ABSTRACT

The self-compacting concrete (SCC) is a high-performance concrete in which the utilization of vibration or compaction no more required. The aim of this study is to investigate the compressive strength of SCC obtained from stone chips and brick chips as coarse aggregate and find out which aggregate is better in compressive strength. For experimental setup, two types of coarse aggregates are used in this study; stone chips and brick chips. Sylhet sand is used as fine aggregate. Water cement ratio 0.4% and polycarboxylic ether 1% as super plasticizer are used by weight of cement. Moreover, two types of mix ratios namely 1:1:2 and 1:2:4 are used by volume. All cylindrical specimens (Diameter = 100 mm and height = 200 mm) are tested at the age of 7, 14 and 28 days. It is observed that the slump flow value and the compressive strength of SCC made with stone chips are higher than that of brick chips as coarse aggregate. Based on the tested results, stone chips are highly recommended to use as coarse aggregate in SCC as it provides better compressive strength.
