Abstract: In order to solve the problems of low sensitivity, low accuracy, and long time consumption in traditional fibre nano concrete compressive strength testing methods, a method for detecting the compressive strength of fibre nano-concrete under continuous load is proposed. Prepare fibre nano concrete using cement, coarse and fine aggregates, nanomaterials, steel fibres, polypropylene fibres, etc. and cure the prepared specimens. Build a loading device using testing machines, jacks, etc., apply continuous loads to the specimen using the loading device, record the specimen data under continuous loads, eliminate outliers in the specimen data, and combine with the fibre nano concrete compressive strength testing model to obtain relevant testing results. The experimental results show that the maximum sensitivity of this method is 0.97, the accuracy is between 92.1% and 98.2%, and the maximum detection time is 177.23 ms, which has the characteristics of high accuracy and short time.

Keywords: continuous load; fibre nano-concrete; compressive strength detecting; loading device; detection model.
