Description
【Technical field】
The utility model is related to the test devices of a kind of fiber and concrete interface cohesive force.
【Background technology】
Fiber concrete is made with discontinuous staple fiber or continuous fiber using cement mortar, mortar or concrete as matrix
By the general name for the cement-base composite material that reinforcing material forms.The destruction of fiber concrete is usually first from concrete substrate
Cracking starts, and concrete substrate will produce a large amount of microcracks under external force and internal stress effect, when to expand to fiber attached in crack
When close, add the fiber in concrete and play the development that bridge joint prevents this process, and the size of cracking resistance effect finally takes
Certainly in fiber and basal body interface adhesive property and fiber itself mechanical property.Therefore, in the experimental stage, if can test
Go out the interface binding force between single fiber and concrete substrate, you can big to evaluate cracking resistance effect of the fiber in concrete
It is small.There are not the equipment of direct this performance indicator at this time, the present invention to utilize the work of existing electronic fiber strength tester on existing market
Make principle, design specialized mold, conveniently and efficiently to test the withdrawal force between single fiber and concrete, in this, as the two
