结果表明,在试验中随着石膏粉和玻璃纤维的加入量的增多,UPR的收缩率一直降低；丙酮在量较少的时候UPR收缩率增加,在（大于15份）时其收缩率下降.丙酮的添加可以提高UPR抗压强度,当达到20ml是抗压强度为63856.42KN/㎡；石膏粉的添加在份量较少时能提高UPR的抗压强度,也就是在10g时抗压强度达最大55032.37KN/㎡,但当（＞10g）随着量的增加其抗压强度反而降低；随着玻璃纤维的添加其UPR的抗压强度也随着增加,当达到20份时其抗压强度最大58391.58KN/㎡.

The result showes that with the increase of gypsum powder and glass fiber,the contraction rate of UPR reduced during the test; The contraction rate of UPR increased when the quantity of acetone was relatively small.The contraction rate declined when the quantity was bigger than 15%.The addition of acetone can improve UPR compressive strength.When the quantity of acetone reached at 20 ml,the compressive strength was 63856.42 KN / ㎡; The addition of gypsum powder can improve the compressive strength of UPR when the quantity was small,it is to say that the compressive strength reaches its max 55032.37 KN / ㎡ when the quantity of gypsum powder is 10g.But with the increase of gypsum powder(when >10g)the compressive strength would be reduced; With the addition of glass fiber,the compressive strength of UPR would be increased as a result,when the quantity of glass fiber reaches 20%,the compressive strength would reach its max 58391.58 KN / ㎡.
