Green mortar based on sidoarjo mud nano filler and hydrogel for environmentally friendly repair material / A. Fauzi Afriansyah

Abstrak
The demand for concrete in Indonesia continues to increase in line with infrastructure development. One of the challenges faced is cracking in concrete which can reduce its compressive strength and durability. Self-healing concrete offers a solution by utilizing internal healing agents one of which is superabsorbent polymer (SAP). However the use of SAP tends to increase porosity and decrease compressive strength. To address this issue Sidoarjo mud nanofiller which has a high mineral content is added as it has the potential to improve the mechanical properties of mortar. This study aims to determine the effect of combining nanofiller and hydrogel on the physical properties (flow bulk density porosity) mechanical properties (compressive strength) and healing capacity (crack observation and sealing efficiency) of green mortar (geopolymer mortar). The mortar was tested at 28 and 56 days for bulk density compressive strength and porosity as well as crack observation and sealing tests after wet-dry curing. The results showed that the addition of hydrogel decreased the flow value and increased mortar porosity while the combination with nanofiller reduced porosity and maintained bulk density. At 28 days the highest bulk density was found in the REF specimen at 2294.67 kg/m sup3 while at 56 days the highest was 2336.00 kg/m sup3 for the REF SAP specimen. The highest compressive strength at 28 days was recorded in the REF SAP specimen at 35.14 MPa and at 56 days in the REF NSL SAP specimen at 37.77 MPa. In terms of healing capacity specimens with both nanofiller and hydrogel showed improved healing ratio and sealing efficiency compared to geopolymer mortar with hydrogel alone. The use of Sidoarjo mud nanofiller in green mortar (geopolymer mortar) with hydrogel can be a potential option for developing environmentally friendly repair materials particularly for constructions requiring high crack resistance and effective self-healing capability.
