Study of Modulus of Rupture on Geopolymer Concrete Temperature Difference Methods of Steam Curing [PDF]

open access: yesE3S Web of Conferences
Geopolymer concrete is concrete without cement. Cement replacement due to cement production has resulted in a global warming effect. Fly ash as a substitute for cement is a waste of coal production containing pozzolan properties.

On the Test of the Modulus of Rupture of Soil Sample

open access: yesSoils and Foundations, 1961
SYNOPSIS This paper presents the relation between the modulus of rupture and the unconfined compressive strength. To obtain this relation, the undisturbed and disturbed soil samples have been used. The test for modulus of rupture is very simple and the necessary amount of sample is not so much, and the reliance of this test is the same as the ...

The Effects of Cracks on the Modulus of Rupture of Concrete

open access: yesJournal of Applied and Emerging Sciences, 2018
The purpose of this study was to experimentally investigate the effects of cracking on the modulus of rupture (MOR) of concrete. When a structural member (e.g. column member) is subjected to dynamic loading, the tensile and compressive parts are interconverted on each stress reversal.
