Laser Induced Breakdown Spectroscopy Technique And Its Application In Concrete

The performance of all its material composition and structure of the composition are closely related, in concrete the active ingredients of cement clinker on the strength and other properties of concrete are closely linked, according to the water-binder ratio we can know that the concrete performance and the dosage of cement has a direct relationship. With the development of science and technology of analyzing materials means more and more, choose what kind of analysis method, can achieve our analysis the task. Laser-induced breakdown spectroscopy (LIBS) is a promising analytical and measurement techniques in the past 10 years has emerged, and was widely used in material analysis, metallurgical industry, medical and other plants fields.This paper reviews the basic principles of LIBS technology and features, and LIBS analysis methods are described, introduced some of the basic principles of spectroscopy. Describes the experimental setup for LIBS studies and experimental samples to study the emission spectra of laser plasma factors. Analysis Rights concrete structure elements of the nature of the relationship between concrete material, analysis of delay lines of the concrete elements, and finally summarizes the main contents of this paper pointed out that use of LIBS measure the significance of concrete technology, and the next research are proposed.
