Product Description
Basic Use: The Ivany Block Structural System, an engineered, reinforced concrete masonry system utilizing the Ivany Block, is a revolutionary and proven concrete masonry unit. The Ivany System adds a new dimension to the performance of concrete masonry as an alternate to cast-in-place steel reinforced concrete walls. Use of the Ivany Block System provides all the necessary high demands for structural performance at cost significantly below that of reinforced concrete walls made with conventional formwork.
Ivany Block Open End units shall be manufactured with a ½ inch lip on the bottom of the block and a protrusion of the lip in the middle of the core shall be provided to hold the vertical bar in the proper position for the outside face. There will be provided two vertical slots in the web of the block for horizontal reinforcing which in turn provides hold for vertical bar inside. Special corner units shall be provided to make possible the proper placement of the horizontal corner bars.
Composition and Materials: Type- Ivany Block Open End Block; Sizes-Standard Modular Dimensions
Limitations: Use of the Ivany Block System is not a pre-engineered method of construction. The size and spacing must be determined by calculations for the particular applications.
Fire Ratings: Define hourly rating required as 1, 2, 3, or 4 hours. Ivany Block shall conform to ASTM E119 with respect to minimum thickness required for various wall assemblies.
