Investigation on Shrinkage Characteristics of Polyester-Fiber-Reinforced Cement-Stabilized Concrete Considering Fiber Length and Content

Polyester-fiber-reinforced cement-stabilized concrete is widely adopted to prevent the shrinkage cracking in pavement engineering. However, effects of fiber length and content on dry temperature are not clear. The relationship between resistance strength also discussed scantily. Hence, five types polyester (1 cm, 3 5 7 9 cm) six (0.1‰, 0.3‰, 0.5‰, 0.7‰, 0.9‰, 1.1‰) were selected prepare fiber-reinforced concrete. coefficients used evaluate resistance. Moreover, relationships among these coefficients, compressive strength, splitting at different curing ages investigated realize prediction polyester-fiber-reinforced This study aimed seek optimal characteristics conveniently for Results show that: increasing can significantly improve concrete, especially shrinkage. should be too long, optimum 0.7‰ cm There was higher correlation strengths while obvious.
