Cement strength estimation method based on width learning under internal influence factors

Abstract

The invention discloses a cement strength estimation method based on width learning under internal influence factors. The method comprises the following steps: building a cement strength estimation index system which comprises the internal influence factors influencing the cement strength, the cement compressive strength on the third day and the cement compressive strength on the 28th day; the method comprises the following steps: collecting detection records of strength of each batch of cement of a cement enterprise over the years, and obtaining compressive strength of cement samples on the third day and the 28th day under different internal influence factors; a width learning model for estimating the cement strength is established, the model adopts a single-layer neural network structure, the internal influence factors serve as model input, and cement compressive strength on the third day or the 28th day is output; model training; and applying the cement strength estimation model to actual cement compressive strength prediction. According to the present invention, the strength nondestructive estimation is performed on the collected cement data, such that the resource waste in the traditional method is reduced, the cement compressive strength detection time is shortened, and the development of the novel cement and the special cement can be easily accelerated.

Description

technical field [0001] The invention belongs to the technical field of cement performance evaluation, and in particular relates to a cement strength estimation method based on width learning under internal influence factors. Background technique [0002] As an important material, cement occupies a pivotal position in the construction industry. Its quality is directly related to the safety of production and life, so quality inspection is of great significance to cement production. Cement compressive strength (CCS) is an important index to detect the quality of cement. From the cement manufacturer's point of view, the compressive strength of the product needs to be improved and stabilized. Therefore, in quality inspection, it is very important to accurately estimate the compressive strength. [0003] In production enterprises, the detection of cement compressive strength is still at the stage of traditional destructive detection method, which is an arduous and time-consumin...
