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

Abstract

The invention discloses a test method and device for in-situ monitoring of strength development of a carbonized product. The method comprises the following steps: putting a prefabricated test sample into a carbonization environment box; placing a temperature sensor at the center of the surface of the test sample; respectively placing a transmitting end probe and a receiving end probe of an ultrasonic sensor on the two sides of a mold of the test sample, and enabling the transmitting end probe and the receiving end probe to be in close contact with the test sample; sealing the carbonization environment box, and introducing mixed gas into the carbonization environment box, so as to enable the air pressure in the carbonization environment box to be increased to preset air pressure; and acquiring and storing effective temperature data and ultrasonic transmission speed data, and processing the collected effective data to obtain a carbonization temperature rise curve and an ultrasonic speedcurve of the test sample. The temperature change of the test sample and the transmission time of the elastic wave in the sample in the carbonization process can be accurately measured, and the strength development process of the carbonized product is effectively reflected.

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...
