摘要：
The paper presents a study of the effect of constant magnetic field on composites used in building industry. The effect of changes was obtained both by direct exposure of the samples to CMF and by using magnetically treated mixing water. Particularly good results were obtained in flexural strength test for (gypsum-phosphogypsum) composite, in which that parameter increased by 30% (from 2.35 to 3.07 MPa), as well as for (cement-fly ash-phosphogypsum) one, in which it increased by 150% (from 2.39 to 6.11 MPa). In compression strength test, that parameter for (cement-fly ash-phosphogypsum) composite improved by 110% (from 7.09 to 14.98 MPa). (C) 2015 Elsevier Ltd. All rights reserved.
