LECA (Light Expanded Clay Aggregate). This free-draining medium is manufactured by mixing sodium with clay and firing in a rotary kiln to burn off the sodium, forming round pellets of various sizes, each pellet having 'honeycomb' spaces inside. These spaces allow nutrients to be taken up by the pellet and released to the plant gradually. aggregates (LECA), which is one of the widespread light-weight aggregates, as a partial replacement to the normal weight aggregates. Eleven beams; were fabricated and tested through the current experimental work for understanding the shear behavior of the reduced-weight reinforced concrete beams. The effects of several variables such
