LECA (Lightweight Expanded Clay Aggregate) is an aggregate made by expanding clay at average 1200 C° in rotary kiln. The Yielding gases are expanded by thousands of small bubbles during this temperature and those will provide many voids and honeycombs in this aggregate by shell structure when melted material become cold.
Using prewetted expanded clay aggregate with similar mix composition, concrete density was 1900 kg/m3 with a compressive strength up to MPa. Although having similar mechanical properties as the waste plastic aggregate, prewetted expanded clay allows better cement hydration process, resulting in lower water absorption of lightweight concrete.
