Cathode Ray Tube (CRT) glass belongs to the group of wastes which are hard be recycled due their toxic metals content. Geopolymers relatively new environmentally friendly materials allow for use different types within matrix. The following paper combines both issues and presents a geopolymer mixture containing discarded CRT as replacement an aggregate. main goal is describe basic mechanical beh...

This work studies the feasibility to employ a combination of volcanic ash (natural waste) with different raw materials in production geopolymers: fly and mining tailing (considered hazardous solid waste), natural pozzolan, metakaolin. study compares properties geopolymers based on ash, metakaolin, relation 1:1 addition NaOH 15M Na2SiO3 as alkali activators. FTIR XRD assays mechanical tests were...

Due to its unique qualities, concrete is the most extensively utilized substance in construction sector after water. However, because one ton of Portland cement produces about CO2, manufacturing process has considerable disadvantages. As a result, an alternative appears be required. Geopolymer new and environmentally friendly cementitious material that can used place cement. Chemically mechanic...

Sensors and new materials can support optimised concrete maintenance, produce the data needed to justify new, low carbon structural designs. While these technologies are affordable, process of manual installation in a construction context comes with acute unfamiliar risks productivity, personnel safety, confidence quality workmanship. The smart using robotics could address some issues, but ther...
