Abstract

This study examines superabsorbent polymer (SAP) absorption, mechanical strength, hydration, and electrical resistivity of glass powder modified cement pastes. The absorption of SAP was monitored using optical microscopy and shown to be higher when glass powders were used. Addition of SAP was found to improve hydration due to internal curing. The cement pastes with SAP exhibited a decreased compressive strength due to macrovoid formation. The glass powder modified cement pastes experienced a large reduction in electrical resistivity as a result of SAP addition; increased pore connectivity in these cement pastes is suggested as a possible cause of the reduction in electrical resistivity.
