The Strength Test of Concrete During Highway Engineering Construction
Concrete is one of the most widely used materials in civil engineering construction in China.Its strength and performance will directly determine the safety and stability of the structure.However,accord-ing to the actual investigation,the traditional concrete inspection method mostly takes sampled cubic samples for testing.Once the construction quality supervision effect is not good,it is easy to lead to a large deviation between the test results of concrete performance index and the actual situationBased on this,this paper will analyze and discuss the test method of concrete strength in the process of highway engineering construction,take the ultrasonic rebound synthesis method as the test means,and take the recycled concrete as the re-search object,through the measurement of rebound value and sound velocity value,the strength measurement regression curve is built to ensure the accurate evaluation of the compressive strength of concrete.After re-search,it is found that the ultrasonic echo synthesis method adopted in this paper fits the regression formula with high accuracy and outstanding correlation,which can effectively meet the specification requirements,the calculation error is small,and has a certain promotion value.
