Evaluation of strength and durability performance of self-compacting mortar incorporation of nano-Al2O3and fly ash

Evaluation of strength and durability performance of self-compacting mortar incorporation of nano-Al2O3and fly ash

This article presents a comprehensive evaluation of the performance of selfcompacting mortar (SCM) incorporating Al2O3 nanoparticles (NA) and flyash(FA). In this study the construction cost of SCMs was compared withnormal concrete cost. Compressive and flexural strength of SCMs was alsoinvestigated to evaluate mechanical properties. The durability performancewas assessed by means of water absorption, electrical resistivity and rapidchloride permeability tests. Also the SEM photos of samples ...

Interaction Effect of Usage of Polypropylene Fiber and Zeolite on Strength Parameters of Silty Sand

Interaction Effect of Usage of Polypropylene Fiber and Zeolite on Strength Parameters of Silty Sand

Due to the increasing cost of high quality materials needed for different geotechnical projects, engineers try to improve the physical properties of local soils through- out different methods and techniques. This paper investigates interaction effect of usage of polypropylene fiber and zeolite on strength parameters of silty sand. Accordingly, usage of an additive material besides fiber, raises an issue about synergistic interaction effect on soil strength. Usage of fiber or zeolite lonely is ...

Investigating the Effect of Applying Polypropylene Fiber on Compressive Strength of Self-consolidating Concrete

Investigating the Effect of Applying Polypropylene Fiber on Compressive Strength of Self-consolidating Concrete

Mechanical characteristics of fiber concrete is affected by type, percentage, length to diameter ration, context resistance, size and shape of fiber, sample preparing method and size and shape of sand material. Therefore, in order to use in each case, mix design should be prepared and it must be tested. The current research have been designed and conducted in order to examine the effect of applying propylene fiber on pressure behavior of Self- consolidating concrete. Washed sand with fineness ...
