Mechanical properties prediction of normal and high strength geopolymer concrete

الملخص EN

The production process of cement is the main binder material in concrete usuallyaccompanied by carbon dioxide emission.

Therefore, geopolymer concrete (GPC)an alternative binder material was developed as a replacement for cement.

In orderto make this promising material more common in constructions and applicable fordifferent design purposes further investigations for GPC mechanical propertieswere needed.

This work aims to predicate the splitting tensile strength, modulusof elasticity and flexural strength for normal and high strength GPC by derivingnew equations covering a wide range of compressive strength based on dataavailable from previous work.

Equations behavior along the changes incompressive strength from normal to high is adopted in comparisons as illustrated.

The results show that the proposed equations, as compared with other equationsestablished by previous works, provide a steady behavior for the various values ofcompressive strength especially for high strength.

The coefficient of variation(COV) used as additional comparison criteria, and shows that the proposedequations provide better estimation of GPC mechanical The production process of cement is the main binder material in concrete usuallyaccompanied by carbon dioxide emission.
