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

E3S 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.

Predicting Catalyst Extrudate Breakage Based on the Modulus of Rupture. [PDF]

J Vis Exp, 2018
The mechanical strength of extruded catalysts and their natural or forced breakage by either collision against a surface or by a compressive load in a fixed bed are important phenomena in catalyst technology. The mechanical strength of the catalyst is measured here by its bending strength or flexural strength.

The effect of concrete vertical construction joints on the modulus of rupture

Case Studies in Construction Materials, 2014
The purpose of this study is to experimentally correlate the compressive strength (f′c) of concrete to the modulus of rupture (fr) for plain concrete beams with a vertical construction joint placed at their center. The ACI code provides a formula for the

MODULUS OF ELASTICITY AND MODULUS OF RUPTURE OF ELECTRICAL PORCELAIN

Journal of the Ceramic Association, Japan, 1937
Measuring the modulus of elasticity and that of rupture for electrical porcelain with the small cross sectional area, the following results have been obtained.1. When the grain size of green body is reduced, the modules of rupture and the modulus of elasticity become larger, but the increase of the latter is smaller when compared with that of the ...
