The aim of this study is to compare the mechanical and physical properties different geopolymer mortars made with granulated blast furnace slag as a source material, NaOH (8 M) activating solution, three types fine aggregates (air-cooled slag, biomass bottom ashes, silica sand). samples were an aggregate/geopolymer ratio 3/1, (density mercury intrusion porosimetry), (compressive flexural streng...

– Geopolymer concrete is an effective alternative to reduce adverse impacts of cement manufacturing on environment and achieving sustainable development. Road construction a major sector, which utilizes in large volume, having significant effect environment. The present work presented two parts. In the first part, evaluation CO 2 emission for 1m 3 geopolymer ordinary Portland has been carried o...

Geopolymer concrete that has polymer formwork is very likely to be used as reinforced material with several advantages. The advantages of geopolymer when compared portland cement are: resistant acidic environments (corrosion resistance), better bond strength reinforcement material, stable at high temperatures, higher fracture energy. Previous experimental studies found the tensile strength, and...

Activation of class F fly ash with the 10 M sodium hydroxide and sodium silicate and its geopolymeric products were analysed under quasi-isothermal mode of DSC, FTIR and TG/DTA techniques. Before adding in concrete, expanded polystyrene beads were prewetted with the styrenebutadienestyrene latex aimed at to improve their bonding with geopolymer. Lightweight mortars/concretes were made from geop...

The use of natural fibers in reinforced composites to produce eco-friendly materials is gaining more attention due to their attractive features such as low cost, low density and good mechanical properties, among others. This work thus investigates the potential of waste abaca (Manila hemp) fiber as reinforcing agent in an inorganic aluminosilicate material known as geopolymer. In this study, th...

The effective activation and utilization of metakaolin as an alkali activated geopolymer precursor and its use in concrete surface protection is of great interest. In this paper, the formula of alkali activated metakaolin-based geopolymers was studied using an orthogonal experimental design. It was found that the optimal geopolymer was prepared with metakaolin, sodium hydroxide, sodium silicate...

Geopolymers are a class of X-ray amorphous alkali aluminosilicate gel binder materials with potential applications in a wide range of areas. In particular, geopolymers can provide significant improvements over traditional Portland cement technology in applications requiring resistance to acid or salt attack, or thermal stability at temperatures up to 1000°C. The quasi-zeolitic nature of some of...

Abstract Portland cement is the most popular material used in construction. It characterized by exceptional thermal, mechanical, and durability properties. However, an alarming amount of pollution energy consumption generated during its production [1]. Scientists are continuous search to find new environmentally friendly cementitious materials, exhibiting good mechanical Geopolymer looked at as...

In order to reduce the carbon emission of planting concrete in process preparation, and realize application large amounts red mud geopolymer, this study, high silicon source materials blast furnace slag are added a content base geopolymer concrete, which can remove dependence on ordinary Portland cement provide new direction for comprehensive utilization mud. paper, effects different A (Alkali ...
