A test method and device for in-situ monitoring of carbonized product strength development

Abstract

The invention discloses a test method and device for in-situ monitoring of strength development of carbonized products. The method comprises placing a prefabricated test sample in a carbonization environment box; placing a temperature sensor at the center of the surface of the test sample; Place the transmitting end probe and the receiving end probe of the ultrasonic sensor on both sides of the mold of the test sample respectively and keep the transmitting end probe and the receiving end probe in close contact with the test sample; The gas is mixed in the environment box to increase the air pressure in the carbonization environment box to the preset air pressure; the effective temperature data and ultrasonic transmission speed data are obtained and saved, and the collected effective data are processed to obtain the test sample Carbonization temperature rise curve and ultrasonic velocity curve. The invention can accurately measure the temperature change of the test sample and the transmission time of the elastic wave in the sample during the carbonization process, so as to effectively reflect the strength development process of the carbonized product.

Description

technical field [0001] The invention relates to the technical field of strength development testing of carbonized products, in particular to a testing method and device for in-situ monitoring of strength development of carbonized products. Background technique [0002] Carbonized product is a kind of material that is mixed with carbonized cementitious material and aggregate, and then added water and then pressed or stirred. The strength development mechanism is carbonized cemented material and carbon dioxide. It has the characteristics of fast strength development and excellent durability. At the same time, the preparation of carbonized products by using steel slag and other bulk industrial waste rich in calcium silicate mineral phase is of great significance to the utilization of solid waste resources and the low-carbon sustainable development of the building materials industry. [0003] The strength development process of carbonized products is accompanied by the signific...
