聚酯牵伸丝纤维对水泥胶砂强度影响的实验研究

EXPERIMENTAL RESEARCH ON THE INFLUENCE OF POLYESTER DRAWN YARN FIBRE ON THE CEMENT-DETERMINATION OF STRENGTH

通过实验研究了不同掺量、不同长度的聚酯牵伸丝纤维对水泥胶砂强度的影响 ,找出了最佳掺量 ;并进行了耐久性实验研究。实验表明 ,在最佳掺量下 ,可提高水泥 2 8d的抗折强度 35 3%、抗压强度 17 1% ;

The influence of polyester drawn yarn fibre ha ving different mix amount and length on the cement\|determination of strength we re stutided and the optimum mix amount has been found.Meanwhile,the durability o f the polyester drawn yarn fibre also have been tested.The experiment indicates that the bending strength of 28 days of cement can be increased by 35.3% and the compressive strength can be increased by 17.1% under the optimum mix amount.Mor eover,the polyester drawn yarn fibre turns out have quite good durability. \[
