Pressure-Temperature-Volume Change Relationship for a Hydrophilic Polyurethane Grout
In this study curing behavior of a hydrophilic polyurethane grout under controlled volume change with varying water-to-grout ratio was investigated to develop pressure (P) - temperature (T) - volume change (V) relationship. Variation of maximum pressure and maximum temperature with water-to-grout ratio varying from 0.5 to 8 was quantified. Highest measured pressure was 1.3 MPa (180 psi) for allowed volume change of about 40% and water-to-grout ratio of 1. The maximum pressure (P) decreased with increasing water-to-grout ratio and allowed volume expansion (ΔV) during the foaming process. The maximum temperature increment (T) also showed an inverse relationship with water-to-grout ratio. Based on the experimental results, water-to-grout ratio (W/G) and volume expansion (ΔV) of the hydrophilic polyurethane grout have been related to the maximum pressure and temperature increases during curing.
