Smart Construction for a Sustainable Future
Growing ecological challenges have made green building a necessity rather than a choice. Beyond protecting the environment, it improves the quality of life and reduces long-term maintenance costs. High-quality, insulating, and eco-friendly materials are key, like the Ashkalit 268 cement block, which holds a high energy rating under Standards 5281 and 5282, along with the Green Mark certification from the Standards Institute of Israel.
Block Made Only of Naturally Occurring Raw Materials
A major advantage of the white block is that it is made solely from naturally occurring raw materials—sand, cement, and lime—without aggregates from radioactive volcanic sources. As a result, its radiation levels are far below the maximum allowed under Israeli Standard 5098 for natural radioactive elements in building products. The block’s high air content also makes it lightweight and uses less raw material per block than other building materials.
Minimal Natural Resources, Minimal Energy
A true green product minimizes environmental impact during manufacturing, and the Ashkalit 268 white block meets this standard. Its raw materials use only ⅛ to ⅕ of the natural minerals needed for conventional concrete products. They are also produced with significantly less energy; for example, the energy consumption for making cement for the white block is 70% lower than that required for cement used in regular concrete blocks.
Reduction of Waste and Refuse
The white block’s monolithic structure enables contractors to reuse cut blocks, reducing site waste. Manufacturing leftovers are ground into lightweight gravel, used as filling and insulation material in various projects, especially TAMA 38 (National Outline Plan) initiatives. If a structure is demolished, any unrecycled block residues naturally blend into the environment without causing harm.
Significant Savings for the Construction Contractor
Green building with the white block offers key operational advantages. Its easy cutting allows maximum material use, while its low specific gravity saves up to 23% in ceiling reinforcement steel and around 10% in structural elements overall. It also reduces the need for heavy handling equipment. Despite its light weight, the block’s vertical compressive strength exceeds standard requirements, enabling further savings in girdle casting, mold making, and the use of concrete, cement, and timber.
