    • Alkali activated (Geopolymer) concrete is an excellent and viable alternative to Portland cement based concrete as it can be produced using industrial by-products such as Ground Granulated Blast Furnace Slag (GGBS) and fly ash (source of reactive aluminosilicates) along with alkali activators (for ex. Sodium hydroxide, Potassium Hydroxide, Sodium Silicate, Potassium Silicate etc.). NCCBM took up an initiative to conduct a research study on development of geopolymer concrete and study its properties for precast products. Several mix trials were conducted for development of geopolymer concrete mixes of different strength range, by varying the proportions of GGBS and fly ash in total cementitious content, at different concentrations of chemical activators. An experimental pavement stretch was cast in NCCBM premises using geopolymer paver blocks. Based on study, a patent has been filed for interlocking paver blocks and is under consideration. NCB drafted guidelines for developing geopolymer concrete mixes for precast products. Based on those guidelines and recommendations, IS 17452 (Use of alkali activated concrete for precast products- Guidelines) was formulated in 2020. Based on expertise gathered in previous study, a new research project was taken up with an aim to study the hardened and durability properties of normal and high strength geopolymer concrete and preparation of guidelines for structural design using geopolymer concrete based on its mechanical properties, whose validation has been done by limited testing on reinforced geopolymer concrete beams of selected grades.
