Abstract: To achieve strain-hardening behaviour in a cementitious composite, various factors should be taken into account during the material production. These factors are generally associated with three phases: the fibre, the matrix and their interface. This study focuses on exploring the role of the matrix in the making of self-consolidating strain-hardening cementitious composites (SHCC) and developing suitable matrix compositions with high volume fly ash for self-consolidating SHCC. Generally, cement pastes or mortars are used as the matrices in SHCC. This use results in a high content of cement in SHCC and increases the environmental and economic production costs of SHCC. The usage of high volume fly ash to reduce the content of normal cement is an effective solution to this problem. In this investigation, self-consolidating SHCC was produced by using flowable fly ash-cement pastes along with micro polyvinyl alcohol fibres.
