Strength Assessment of Bamboo Trunk Ash (BTA) and Grinded Snail Shell (GSS) As Additives in Self-Compacting Concrete (SCC)

Abstract

This research examined how bamboo truck ash (BTA)/grinded snail shell (GSS) can be use as partial replacement of cement in self-compacting concrete. One hundred and Twenty (120) specimens were produce, the water-powder (cement+GSS+BTA) ratios were 15%BTA/0%GSS, 10%BTA/5%GSS, 5%BTA/10%GSS, 0%BTA/15%GSS, and SP430 from 0%, 1%, 2% and 3% while other mix components were kept constant. Laboratory investigation results showed that sample at 7 days, 1 % COMPLAST SP430 and 2% bamboo trunk ash/grinded snail shell, the maximum average compressive strength was 8.81N/mm2 also at 28 days 1%, 2 % bamboo trunk/grinded snail shell, maximum average compressive strength was 19.85N/mm2. Self-compacting concrete criteria on the fresh concrete mix ratio show that at 2% and 3% SP430 complast (as super plasticizer) addition with 15/0, 10/5 and satisfied self-compacting concrete criteria. Compressive strength of concrete was obtained within the range of 15N/mm2 to 18.74N/mm2.The strength was examined using standard deviation and they were within the acceptable limits. The significance of this work lies in its attempt to provide information on the performance of self-compacting concrete and its major advantages in saving time, labor and environmentally friendly as noise from vibrator is completely eliminated.
