One of the main challenges facing Civil Engineering community is to modify cement quantity in the mix design by admixtures to enhance the mechanical properties.
According to more than 1000 data from literature, mechanical characteristics of concrete modified with FA were discussed.
The statistical variation with modeling were achieved by set of data.
The cement was replaced up to 70% with FA (weight of dry cement) and by cube of concrete testing up to 90 days of curing time and different w/c ratio.
The compressive strength of concrete varied from 18-67 MPa, while, for modified concrete with FA, compressive strength ranged from 21-94 MPa, tensile strength ranged from 1-9 MPa and flexural strengths ranged from 3 - 10 MPa.
The w/c ratio of concrete modified with FA varied from 0.24-0.53, also the FA content varied from 0-50 %.
Vipulanandan correlation model was effective by connecting mechanical properties and compare with Hoek-Brown model.
The nonlinear model was used to investigate the effect of FA on properties of normal and high strength concrete.
Study results presented a worthy correlation between compressive strength and curing time, w/c ratio and FA content.
By using the interactive linked (model) for compressive, tensile, and flexural strengths of concrete quantified well as a function of w/c ratio, curing time and FA content by using a nonlinear relationship.
