Alternative Clinker Technologies for Reducing Carbon Emissions

Calcium sulfoaluminate cements (CSACs) are a belitic type of cement, which were developed in the 1970s with the intention of compensating for the lower early-age strengths typically observed in belite-rich cements . Typical raw materials used in the production of CSACs are limestone, calcium sulfate and aluminum-rich minerals or A CO 2 -negative concrete would be a true climate friend.

Spain Cement industry news from Global Cement

Spain: Cementos Molins has processed 75,000t of waste into alternative raw materials for use in its cement production since opening its Barcelona alternative raw materials plant in September 2022. The plant has a production capacity of 200,000t/yr. It produces the materials from construction and demolition waste and various industrial by Valderrama et al. compared the environmental impacts of using sewage sludge as a fuel substitute and as a raw material in a cement plant using the mid-point and end-point analysis method, LCA assessment. The results show that for raw material and fuel substitution, the CO 2 equivalent per kg of clinker produced is 904 g and 898 g, Review on the use of sludge in cement kilns: Mechanism,

Materials Free Full-Text Wood Ash as Sustainable Alternative Raw

Concrete is the most widely used material in the construction industry after water due to its good durability, mechanical properties, and low cost [1,2,3].According to the Global Cement and Concrete Association, 14 billion m 3 of concrete and 4.2 billion tons of cement were produced worldwide in 2020 [].Cement is the component of concrete that Clinker is produced by heating crushed limestone and a mix of other materials (clay and sand) to 1450 °C in a rotary kiln. Clinker is later ground down to a fine powder and mixed with gypsum and other ingredients to make cement. The rotary kiln is the heart of the manufacturing process where raw materials are heated up and decarbonisation ofOur 2050 Roadmap The 5C Approach: Clinker Cembureau

Different Approaches to Develop More Sustainable Concrete Alternatives

As important as it is, sustainability related with the concrete material is more than reducing the amount of cement in concrete mixes. In effect, there can be other types of contributions to a sustainable development using this fundamental material. The purpose of this book chapter is to analyse some of these approaches, in particular, Historically, the primary fuel used in cement industry is coal. A wide range of other fuels such as gas, oil, liquid waste materials, solid waste materials and petroleum coke have all been successfully used as sources of energy for firing cement-making kilns, either on their own or in various combinations.Alternative Fuels in Cement Manufacturing IntechOpen
