Feasibility of ECC with high contents of post-processed bagasse ash as partial cement replacement

Sujata Subedi et al.

Summary: The study found that with an increase in PBA content, workability and compressive strength of the composite materials decreased while surface resistivity increased. PBA composites outperformed those using FA in terms of compressive strength and surface resistivity, but exhibited shortcomings in crack-tip fracture toughness and tensile strength of the concrete.

Evaluation of Alternative Sources of Supplementary Cementitious Materials for Concrete Materials

Sujata Subedi et al.

Summary: This study characterized and evaluated the use of reclaimed fly ash and reclaimed ground bottom ash as alternative sources of supplementary cementitious materials. The results showed that both materials met the required standards and performed better than conventional fly ash in certain aspects. Therefore, reclaimed fly ash and reclaimed ground bottom ash can be important substitutes in concrete materials.

Effect of pores on the mechanical and durability properties on high strength recycled fine aggregate mortar

Rebeca Martinez-Garcia et al.

Summary: The study aims to investigate the impact of recycled fine aggregate on the mechanical and durability performance of mortar. The results show that mortar with 25% recycled fine aggregate performs better, but it also has an increase in pore structure.
