Study on the Physico-Mechanical and Durability Properties of Fiber-Reinforced Alkali Excited Materials
Selecting polypropylene fibers(PP)and basalt fibres(BF),a total of 13 groups of fiber reinforced alkali excited materials(AAC)were prepared by using 6 different volume dosages to study the effects of fiber dosage and fiber type on the workability,compressive and flexural strengths,cracking and seepage resistance of AAC,and the introduction of the fiber reinforcement index I was introduced for further discussion of the various properties.The results show that polypropylene fibers(PP)are higher than basalt fibers(BF)in improving flowing property at the same dosage,but have a lower effect on compressive strength,whereas BF has a higher flexural strength enhancement rate of 17.3％than PP;PP can increase the seepage resistance grade by 2 grades at a dosage of 0.5％,but BF has almost no effect on the improvement.I can reflect both the dosage of the fibers and the physical properties.When I is between 100 and 350,its flexural and compressive properties can be further improved,but after more than 350,they will have or even intensify the negative impact on all the properties;the ACC doped with BF had a lower threshold value.
