Abstract
A new measure control technology for testing the compressive strength of concrete structures which is called noumenon sampling method is put forward. The concrete strength of different curing time was got from the application of noumenon sampling method in the detection of winter construction concrete structures. According to the grey system theory, the GM (1, 1) model is used to establish the prediction model of the concrete strength. The established model can be used to determine when the concrete structures will achieve the critical strength in frost resistance. This determination can provide scientific basis for the quality control of concrete in winter construction. Analysis and calculation show that the predictions agree well with the experimental data. The result is ideal. So the prediction model can be applied as a new method for controlling the concrete structures strength in winter construction.
