Why Expanded Clay Aggregate (ECA) Is Preferred Against Other Aggregates
Expanded Clay Aggregate (ECA) has great resistance against acidic and alkaline substance with a pH of nearly 7 which makes it neutral in chemical post reaction with concrete.
Expanded Clay Aggregate (ECA) has lightness, durability, non-decomposability, insulating capabilities, chemical resistance, pH neutrality and due to its structural stability it is considered as the best lightweight aggregate for concrete in roofing, flooring, bridge construction and many more. It has a density that is less than or equal to 460 Kg/m3.
Expanded Clay Aggregate (ECA) is environment-friendly, natural, indestructible, non-combustible material, it’s highly impervious tao attack by insects, gnats and termites. Lightweight concrete can be basically classified into two:
Aerated Concrete: Has a very light weight and low thermal conductivity. It requires an auto-claying process to obtain certain level of strength and this involves special manufacturing plant and it in turns consumes high energy.
Expanded Clay Aggregate (ECA) Concrete: It has higher strength but exhibits higher density and it has a very low thermal conductivity.
