Characterizing the Mechanical Properties of Sustainable Modified Cementitious Grout for Semi-Flexible Mixture

Abstract

Grout could be a cement-based fabric with high quality and workability that permitting it to be infused into little splits or cracked zones. It is ordinarily utilized to fix concrete splits or gaps, but it may be utilized to fill voids beneath metal bases or dig anchors or soil gravities filling. Moreover, grout is utilized effectively within the generation preparation of the semi-flexible asphalt blends. This research aims to characterize the impact of incorporating proposed ash as a supplementary cement material (SCM) on the mechanical properties of developed grout. The developed grout comprised Ordinary Portland Cement (OPC), silica fume (SF), palm frond waste ash (PFWA), superplasticizer (SP), and water. Diverse extents of specified materials were utilized to characterizing the created grout through flowability, compressive strength, and flexural strength tests. Results disclosed that the stream time diminishes with an increased water/binder ratio (W/B). On the other hand, the compressive strength and flexural strength of the grouts comprised OPC+PFWA reveals an ideal dose that shows superior mechanical properties, namely, 10% PFWA. As the main conclusion, the mechanical properties of sustainable modified cementitious grout are highly affected by grout ingredient types, dosage, and properties.
