Microstructural and Durability Properties of Concrete Containing Alccofine and Zeolite Reinforced with Polypropylene Fibres

Abstract

Objectives: To study the microstructural and durability properties of a polypropylene fibre reinforced concrete (PPFRC). Methods: In this research 10% and 15% of cement was replaced by natural zeolite and Alccofine and four different volume fractions of polypropylene fibre (0, 0.1, 0.2, 0.3 and 0.4 percent) were utilized to improve the strength and durability properties of concrete. Scanning Electron Microscope (SEM) was used to observe the crystal structure and that interfactial transition zone (ITZ). Findings: SEM Results indicates that fibres changes the microstructure, reduces Ca(OH 2 ) through the secondary C-S-H gel formation and hence the voids get reduced Six concrete mixtures with water to binder ratio of 0.50 were cast. Novelty: Addition of polypropylene fibre has greatly improved the durability properties of concrete containing alccofine and zeolite.
