摘要

The major element of Ca directly affects the quality of the cement, so how to obtain its concentration fastly and accurately becomes especially significant. In this study, all the objects we chose to analyze were the powder cement without any pre-treatment. Firstly, We got the spectrum data on the surface of the cement samples by using Laser-induced breakdown spectroscopy technique, then we built the multivariate quantitative analysis models which were based on the partial least squares (PLS) after the data had been pre-processed. Experimental results showed the feasibility of the LIBS technique within a certain accepted range, and indicated that LIBS will have great potential to be applicated more extensive in the future.
