LIGHTWEIGHT CONCRETE May consist of lightweight aggregates are used in ordinary concrete of coarse aggregate and sand, clay, foamed slag, clinker, crushed stone, aggregates of organic and inorganic. It used in different common shapes such as light weight aggregate concrete [1], concrete without fine [2] or concrete with bubble [3]. It is replaced by normal concrete in several applications becau...

The Cemex facility manufactures Portland cement and is located in Lyons, Colorado, approximately 20 miles from Rocky Mountain National Park. There are two BART-eligible units at the facility: the dryer and the kiln. The Lyons plant was originally constructed with a long dry kiln. In 1980, the kiln was cut to one-half its original length, and a flash vessel was added with a single-stage preheate...

The article is devoted to the study of effect theKhojakulsandstone deposit Karakalpakstan on physical and mechanical properties Portland cement based clinker containing unbound calcium sulfate.

The jarosite residue is a harmful byproduct of the zinc hydrometallurgical process and has been classified as hazardous waste due to its high content heavy metals poor stability. In this work, recovery valuable by synergistic disposal with cement kiln investigated. A series investigations were undertaken assess effect amount residue, roasting time, addition CaCl2 on phase transformation migrati...

Cement manufacturing is one of the most energy intensive processes and is accountable for substantial pollutant emissions. Increasing energy costs compel stakeholders and researchers to search for alternative options to improve energy performance and reduce CO2 emissions. Alternative fuels offer a realistic solution towards the reduction of the usage of fossil fuels and the mitigation of pollut...

The use of CSA cement in practice has been hindered by its unstable performance and short shelf-life caused the prehydration clinker. In this study, effect ambient humidity on rate process clinker was investigated. degree, ageing progress, dynamic change mineral composition exposed to five different relative humidities (ranging from 23% 98%) for up 180 days were studied. Experiments revealed th...
