· The manufacture of Portland cement is a complex process and done in the following steps grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C. During this process, these materials partially fuse to form nodular shaped clinker by broking of chemical ,The invention relates to composite portland cement, which mainly comprises the following raw materials by weight percent 20% to 30% of construction waste micropowder, 15% to 25% of lead and zinc mine tailings, 10% to 15% of mineral admixture, 3% to 5% of modified phosphogypsum and 40% to 50% of cement clinker. The preparation method of the composite portland cement comprises the preparation
· Portland cement, arguably one of mankind's most important manufactured materials, was invented and patented by Joseph Aspdin from Leeds in 1824. Aspdin produced cement by heating powdered limestone mixed with clay in a furnace, and grinding the resulting clinker to a powder. He called the product "Portland Cement" because of its , · This paper investigates the creation of high-density impermeable concrete. The effect of the ment, fly ash, and limestone” composite binders obtained by joint grinding with superplasticizer in the varioplanetary mill on the process of structure formation was studied. Compaction of structure on micro- and nanoscale levels was characterized by different techniques X-ray
