Abstract

Superabsorbent materials are widely used in the manufacture of hygiene products and constitute a significant part of hygiene waste. Hygiene waste recycling is one of the most pressing challenges the humankind seeks to solve today, and any attempt to introduce a new approach toward recycling them is of vital importance. In this work, fresh and hardened properties of cement pastes and self-compacting concrete (SCC) are modified by adding recycled superabsorbent materials (RSA). SCC is proportioned by applying the modified Andreasen and Andersen packing model and using RSA as a rheology modifier. The addition of RSA adjusts the rheology of cement pastes such as flowability, yield stress, and dynamic viscosity and that of self-compacting concrete such as flow time, T50, and v-funnel time. Furthermore, the effect of the RSA on the strength of both cement paste and concrete are investigated.
