Experimental study of using D-D neutron generator to test the element contents in cement raw meal

The article is about how to use 2.5 MeV neutrons which is generated by D-D neutron generator to test main elements in the cement raw meal. The test is not only time-saving, as it can test the major element contents such as Si, Al, Fe, Ca etc in the raw cement, but also easy to operate. By figuring out the proportion of each oxide based on the test results, the product methods in testing element contents in the raw cement thanks to its small deviation of the test result from what we get from the chemical laboratory.
