Self-Consolidating Concrete (SCC) has also brittle characteristics. This is unacceptable for any construction industry. The addition of fibers is one of the most common methods to enhance the tensile strength of concrete. Fiber controls the cracking phenomena and enhances the energy absorption capability of the concrete. On the other hand, the addition of fibers has a negative impact on the workability of fresh concrete. In this paper, a detailed study on the influence of Propylene fibers (PP) on the fresh properties of SCC was carried out. PFs were added into concrete mixes in a proportion of 1.0%, 2.0%, 3.0%, and 4.0% by weight of cement to offset its undesirable brittle nature and enhance its tensile strength. The fresh characteristics were evaluated based on its passing ability, flowability using, Slump flow, Slump T50 Spread time, L-Box and V-funnel tests as well as mechanical performance (compressive and split tensile strength) were also evaluated at 7,14 and 28 days curing. Test results indicate that the passing and filling ability decreased as the substitution ratio of PP increased. Besides, the test result indicates that strength was increased up to 2.0% addition of PP and then decrease gradually.

丙烯纤维增强的自纤维压实混凝土性能

自密实混凝土（SCC）也具有脆性。这对于任何建筑行业都是不可接受的。纤维的添加是提高混凝土抗拉强度的最常用方法之一。纤维控制开裂现象并增强混凝土的能量吸收能力。另一方面，纤维的添加对新鲜混凝土的可加工性具有负面影响。本文对丙烯纤维（PP）对SCC新鲜性能的影响进行了详细的研究。PF以水泥重量的1.0％，2.0％，3.0％和4.0％的比例添加到混凝土混合物中，以抵消其不希望的脆性并增强其抗张强度。根据其通过能力，使用的流动性，坍落度流量，坍落度T50传播时间，还对固化7,14和28天时的L-Box和V漏斗测试以及机械性能（抗压强度和劈裂抗张强度）进行了评估。试验结果表明，随着PP的取代率增加，通过和填充能力降低。另外，测试结果表明，强度增加到PP添加量增加到2.0％，然后逐渐降低。
