On-site traditional methods to build items of homes with affordable prices are time-consuming. The adoption of ready and shaper technology, not only allows faster construction but also a better Economy. For many years Iraq engineering work for roof flatness used to use which is a square board with a length of 400, 600, or 1000mm, yet the procedure and the production need many improvements. One of the disadvantages of this production is the heavyweight and the big amounts of cement that need. So in this research, we made a trial to solve this difficulty using geopolymer concrete and lightweight artificial coarse aggregate. The article describes a new method used first time in Iraq based on the geopolymer concrete technique using fly ash as cementitious material and sodium silicate and hydroxide sodium as alkali-activated solutions and lightweight artificial coarse substances as aggregates enabling to produce lightweight tile. The produced tiles of research results have 35%, 50% less in weight, and thermal conductivity respectively than the normal tile which improved in Iraqi tiles and can be used for roof flatness. |
