Preparation of concrete mixture with LECAT in the production of carrier concrete reduces the weight of concrete in constructions by 25-35% according to the concrete type. Thus, it saves the amount of steel (rebar) used. This creates a secondary effect on reducing the overall weight of the structure. LECAT, the durable and insulated light concrete, is a light concrete aggregate. LECAT concrete should be used for earthquake-resistant structures. This results in flexible concrete. Concrete with LECAT can be used to make tall buildings with same tonnage. Heat and sound insulation is provided in concrete thanks to light LECAT concrete. It provides good sound insulation with materials with rough and porous surfaces. Since concrete with LECAT creates a porous structure, the concrete has more sound and thermal insulation feature. Thanks to the physical structure of the LECAT grain, the concrete with LECAT is highly fluid and easily settled inside the reinforcement, providing resistance to surface wear. Concrete with LECAT is resistant to freezing and thawing, does not deteriorate. It is fire resistant. It prevents the formation of shrinking. It can be produced in any size. It can be produced at any intensity.
