Merab Gamkrelidze, Deputy Head of the Levan Samkharauli National Forensic Bureau, held the meeting with the representatives of construction materials manufacturing companies in Georgia and presented an innovative product created by the Bureau's experts and Georgian scientists.
For the first time in Georgia, with joint efforts of Georgian scientists on the basis of the laboratory of the Forensic Engineering Department of the Bureau, high strength and light construction concrete was created with Georgian raw materials.
The uniqueness of high-strength and light construction concrete lies in the fact that it is produced with Georgian raw materials. In both cases a thermostructured mineral additive is used as a microstructural additive, which is obtained through the modification of tuff, shale and pumice at a temperature of 550-700 degrees and further fine grinding.
High-strength concrete is characterized with its high strength, toughness and high-resistance (and is not prone to cracking). Light construction concrete is characterized by reduced water absorption and high frost resistance.
Georgia is rich in these raw materials. High-strength concrete is the composite of natural stones and additives: cement, water, crushed stone and sand. The manufacturing of high-strength concrete is more cost-effective than the one of imported additives.
The new high-strength concrete produced by the new method will be actively used in the construction industry, in the construction of hydropower plants, bridges, tunnels, airfields and roads.
The use of lightweight construction concrete in the building industry will be mandatory in accordance with the European standard under the Association Agreement with the European Union. The invention of light construction concrete is a joint invention of the forensic engineers of the Bureau and Georgian scientists and meets abovementioned requirements.
Along with quality expert activities, Bureau conducts continuous research activities. The Bureau is currently working on another new innovative invention, which will be another step forward in the Georgian construction industry.
