· This research investigates the simultaneous impact of two different types of steel fibers, nanometakaolin, and nanosilica on the mechanical properties of geopolymer concrete (GPC) mixes. To achieve this aim, different geopolymer concrete mixes were prepared. Firstly, with and without nanomaterials (nanosilica and nanometakaolin) of 0, 2#x0025;, 4#x0025;, .
geopolymer concrete mix is alkaline liquid, for an economic design of concrete, designers should try to use minimum amounts of it in their mixes. Figure 2 shows that, for a 45 MPa concrete, the alkaline liquid requirements are lower when the fly ash content is 320 kg/m3 and the corresponding alkaline liquidtofly ash ratio is
geopolymer concrete, whereas Mustafa Al Bakri et al. [ ] and Jamkar et al. [ ] observed the increase in workability and compressive strength with the increase in neness of y ash. In the present investigation, an experimental work is carried out to study the eect of various concentrations of
Composition of Geopolymer Cement Concrete Mixes Following materials are generally used to produce GPCCs: (i) Fly ash, (ii) GGBS, (iii) Fine aggregates and (iv) Coarse aggregates (v) Catalytic liquid system (CLS): It is an alkaline activator solution (AAS) for GPCC. It is a combination of solutions of alkali silies and hydroxides, besides ...

conventional concrete. Davidovits termed it geopolymer concrete, which is output of chemical reaction between aluminosilie containing source materials and alkaline liquids (alkali polysilies) results a binding gel of SiOAl bonds [2].With reference to the previous test results, its proves that geopolymer concrete has
CONTENT MANUFACTURING PROCESS Geopolymer concrete The geopolymer concrete manufacturing process was carried out at the Central Materials Laboratory based on Buyondo etc. al. report of study. From the research, rice husk ash and Metakaolin was used as activator and mixed with water to form a geopolymer cement. The cement form was .
· The ultrafine fly ash (FA) is a hazardous material collected from coal productions, which has been proficiently employed for the manufacturing of geopolymer concrete (GPC). In this study, the three artificial intelligence (AI) techniques, namely, artificial neural network (ANN), adaptive neurofuzzy interface (ANFIS), and gene expression programming (GEP) are used to .
Geopolymer can be consider as the key factor which does not utilize Portland cement, nor releases greenhouse geopolymer technology proposed by Davidovits(1978) shows considerable promise for appliion in concrete industry as an alternative binder to the Portland proposed that binders could be proposed by a polymeric reaction of alkaline .
Safe and sustainable geopolymer concrete. A basic ingredient of concrete, ordinary Portland cement (OPC) is the most commonly used type of cement for construction of buildings and infrastructure. However, OPC production is responsible for 58 % of all manmade carbon dioxide (CO2) emissions across the globe.
· Marine environments are widely addressed as a serious threat to coastal concrete structures due to higher repair and rehabilitation costs. The rising concerns of climate change and related issues also require marine structures to be resilient and sustainable at the same time. Geopolymer concrete has been given more significant consideration as an alternative, .

The invention of Geopolymers has paved the way for construction industry to use Fly ash based GeoPolymer Concrete with 100 % replacement of cement. Substantial experimental research has been conducted ever since on GeoPolymer concrete which can prove to the sustainable construction material of the future. This paper reviews various materials used for .
· This paper presents the experimental results of an ongoing research project on geopolymer lightweight concrete using two locally available waste materials—low calcium fly ash (FA) and oil palm shell (OPS)—as the binder and lightweight coarse aggregate, respectively. OPS was pretreated with three different alkaline solutions of sodium hydroxide (NaOH), .
