Research on the Preparation and Mechanical Properties of Carbon Fiber Modified Permeable Concrete
In order to explore the modification method of carbon fiber on permeable concrete and clarify the influence of relevant parameters on its physical and mechanical properties,a series of indoor tests were carried out.Considering core parameters such as geometric characteristics and content of carbon fiber,standard specimens were prepared indoors,and the influence mechanism of carbon fiber length and content on the physical and mechanical properties of permeable concrete and its influence on permeability were studied.The results show that the length and content volume of carbon fiber have a great influence on the mechanical properties of permeable concrete.The longer the fiber length and the greater the content,the more significant the improvement effect of the mechanical properties of permeable concrete.Among them,the flexural performance can be increased by up to 70%.However,carbon fiber will also reduce the permeability of modified concrete.Therefore,in the preparation of carbon fiber modified concrete,mechanical properties and permeability should both be taken into account,and reasonable design should be carried out.
