An interesting feature of cements based on calcium sulphoaluminate, C4A3$, is the possibility of utilising as raw materials in their manufacture considerable quantities of industrial wastes and by-products. A particular attention is devoted to the use of chemical gypsum, a waste containing a high amount of calcium sulphate, whose utilization rate in other applications is relatively low. Moreover sulphoaluminate cements having a different composition are examined and the influence of the C4A3$ content on their mechanical properties is discussed

Abstract
An interesting feature of cements based on calcium sulphoaluminate, C4A3$, is the possibility of utilising as raw materials in their manufacture considerable quantities of industrial wastes and by-products. A particular attention is devoted to the use of chemical gypsum, a waste containing a high amount of calcium sulphate, whose utilization rate in other applications is relatively low. Moreover sulphoaluminate cements having a different composition are examined and the influence of the C4A3$ content on their mechanical properties is discussedFile in questo prodotto:
