Doped-fiber can improve the concrete compressive toughness, it's enhancement sort: mixing-doped coarse-fine fiber concrete > single-doped coarse fiber concrete > single-doped fine fiber concrete> plain concrete Introduction For a long time, engineering designers, builders believe that concrete strength grade is the most critical indicators of concrete quality control.
Material The cement is 42.5 R from the XiaoNanHai ,ChongQing; fine aggregate is from ChongQing QuHe river, and the fineness modulus is 0.7;coarse aggregate size is 5 ~ 20 mm; polypropylene fiber was produced by Beijing RongNaier Engineering Materials Co., LTD and Ningbo DaCheng New Material Co., LTD, performance parameters is listed in table 1.
Based on hundreds of testing and engineering experience, the coarse and fine fiber dosage was determined.

The development of this was undertaken by New Zealand Heavy Engineer Research Association (HERA) and Steel Construction New Zealand (SCNZ), with input from the University of Auckland.
Figure 1 FE model of the 1-storey EBF with removable link showing sections of interest to design engineers.
In engineering terms a softer Young’s modulus means that less force is transferred through the slab than through the steel members, which is illustrated in Fig. 5.

Studying the long-term performance and durability of bitumen modified with varying percentages of SiO2 is crucial for its practical application in pavement engineering.
Addressing these aspects will advance our understanding of SiO2-modified bitumen and its potential to transform pavement engineering practices.
