چکیده
This paper presents the results of an experiment study and suggests a theoretical formulation for bond behavior reinforced fly ash-based geopolymer concrete. Three grades (20 MPa, 30 MPa 40 MPa) concrete along with three reinforcement diameters (12, 16, 20 mm) were selected experimental work. The is determined using pullout test, finite element analysis (FEA), test data indicated that strength increases about 1.97 to 2.56 times increase compressive from 20.33 41.12 MPa. For grade specimens, cover diameter ratio (c/db) increased up 4.19 resulted in strength. Then, decreases c/db 5.75, while specimens vice versa. bond-slip relations between FEA good agreement results. coefficient variation (CoV) only 0.01. However, this quite different calculated by fib model.

In this paper, we report the results of our investigation on the possibility of producing foam concrete by using a geopolymer system. Class C fly ash was mixed with an alkaline activator solution (a mixture of sodium silicate and NaOH), and foam was added to the geopolymeric mixture to produce lightweight concrete. The NaOH solution was prepared by dilute NaOH pellets with distilled water. The ...

متن کاملEffect of Glass Powder and GGBS on Strength of Fly Ash Based Geopolymer Concrete
In this study, the effect of glass powder (GP) and ground granulated blast furnace slag (GGBS) on the compressive strength of Fly ash based geopolymer concrete has been investigated. The mass ratio of fine aggregate (fA) to coarse aggregate (CA) was maintained constant. NaOH flakes dissolved in water was used as activating liquid and mixed with fly ash (FA) to produce geopolymer paste or cement...

This paper presents the results of study on effect of various parameters on mechanical properties of fly ash-based geopolymer mortar with bottom ash as partial or full replacement for sand. Compressive strength of samples with 10% bottom ash (BA) was comparable to those with only sand. Further increase in bottom ash content decreased the compressive strength. However, the reverse tendency occur...
