Locally available ordinary Portland cement (PC) of mark P.O. 42.5 from Harbin, conforming to GB/T 175–2007, was used. The fly ash used was Class F fly ash sourced from a construction materials market in Harbin. The chemical composition of cement and fly ash, determined by the XRF test, is detailed in Table 1. Sisal fibers were used in this study.
The fly ash cenosphere is a kind of lightweight hollow particle extracted from the coal combustion by-products, which has attracted widespread interests in the past decades.

The use of fly ash and untreated cenosphere shows a limited contribution to the formation of C–S–H gel, as presented in Fig. 9 b and c, given that CH still dominates the hydration products in mixtures F1 and C0. This indicates that the pozzolanic reactivity of fly ash and untreated cenosphere is not active or not sufficient.
