The compressive strength of a new ureaformaldehyde-based polymer concrete

Abstract

Standard test specimens of ureaformaldehyde-based polymer concrete (PC) prepared with various amounts of ureaformaldehyde (UF) resin and cured at temperatures in the range 90 to 150 ° C for periods up to 21 d were tested in compression. The PC having a resin content of 8% and cured at 110 ° C for about 7 d, developed an ultimate compressive strength of 37 M Pa. The strength values of PC specimens are compared with those of Portland cement concrete (PCC) specimens prepared with different water/cement ratios and mix proportions. For certain mixes the compressive strength of PCC is surpassed by that of PC having a similar binder content and comparable workability. © 1990 Chapman and Hall Ltd.
