Cold-Bonded Lightweight Synthetic Aggregate Involving High Reactive Attapulgite at Different Curing Conditions

This study aimed to develop an eco-friendly, lightweight, and synthetic aggregate (SLA) based on clay suitable for use in structural lightweight concrete. The researchers utilized the cold-bonded pelletization process agglomerate pozzolanic materials, specifically attapulgite extracted from a quarry, crushed into fine filler. appropriate calcination temperature manufacturing this as material is 750°C. A total of 22 mixes were created using combination high reactive (HRA) cement (PC), with replacement rate varying 100-50% by 10% decrement. Different types curing methods, including oven-dry, oven-water, room-water, room-room, applied. properties evaluated determine density, specific gravity, water absorption, impact value, crushing strength, compressive strength. results revealed that it could produce clay-based materials bulk density 793kg/m3 physical mechanical properties. As percentage mixture increased, gravity increased 18.12% 36.61%, whereas values improved 81.83%. This, turn, leads significant boost strength up 100.94%. Furthermore, there noticeable decrease absorption. Moreover, held under oven positively impacts development cement-based composites.
