  • Alternative Raw Materials and Fuels HeidelbergCement

    The conservation of natural resources is part of our sustainable business strategy. That is why we make greater use of waste materials and by-products from other industries as valuable raw materials and fuels. We use alternative raw materials for the production of clinker, which is the most important intermediate product in the manufacture of cement.

  • How Cement Is Made - Portland Cement Association

    The finely ground raw material or the slurry is fed into the higher end. At the lower end is a roaring blast of flame, produced by precisely controlled burning of powdered coal, oil, alternative fuels, or gas under forced draft. As the material moves through the kiln, certain elements are driven off in the form of gases. The remaining elements ...

  • Use of raw materials in the cement industry - VDZ

    In 2015, the German cement industry procured around 41 million tonnes of primary raw materials . Furthermore, approx. 8 million tonnes of alternative raw materials were used to manufacture approx. 31.2 million tonnes of cement. In taking this measure, the German cement industry is making a valuable contribution towards conservation of resources ...

  • Cement - Wikipedia

    Green cement is a cementitious material that meets or exceeds the functional performance capabilities of ordinary Portland cement by incorporating and optimizing recycled materials, thereby reducing consumption of natural raw materials, water, and energy, resulting in a more sustainable construction material.

  • How concrete is made - material, manufacture, making,

    The first step in making concrete is to prepare the cement. One type of cement, Pordand cement, is considered superior to natural cement because it is stronger, more durable, and of a more consistent quality. To make it, the raw materials are crushed and ground into a fine powder and mixed together. Next, the material undergoes two heating ...

  • How Cement Is Made HeidelbergCement Group

    All over the world, cement is one of the most important building materials. Whether for houses, bridges or tunnels, we cannot imagine our modern world without it. Join us for a short tour to experience how cement is made: starting with the extraction of raw materials and ending with the finished product.

  • Raw Material Substitution - Cembureau

    The main raw material used in cement production has traditionally been limestone. Limestone is abundantly available, but over 60% of the industry’s CO 2 emissions are caused by transformation of limestone into lime, called “decarbonation”. Accordingly, part of the route towards a low carbon concrete-built environment can involve limestone substitution.

  • Alternative Raw Materials Irish Cement

    Alternative raw materials, to the basic limestone and shale that have been used to produce cement clinker, are being used in each plant. Limerich plant uses Pfa, a ‘waste’ ash from Moneypoimnt power station to replace shale.

  • Alternative Raw Materials - Systech Environmental

    Alternative Raw Materials Systech uses sustainable methods to manage customers’ non-hazardous waste, beneficially reusing its mineral value to make another product—cement. Calcium, alumina, silica, iron and lime are all used as raw materials in the production of powdered portland cement.

  • Alternative Raw Materials Fuels 2018 World Cement

    It will follow a dual-track program focusing on alternative fuels (waste to energy, municipal waste, RDF, agricultural residues, paper, pulp waste) and alternative raw materials (slag, flyash, pozzolana), gathering international attendees and top-level speakers to share global opportunities, practices, technologies, and perspectives.

  • Alternate Cementitious Materials

    These materials can be used alone or blended with other alternative cementing materials to produce a cement or concrete with properties different than those resulting from the use of portland cement. The use of alternative materials affects cement and concrete properties such as workability, hydration, compressive strength, and durability.

  • Geopolymer: A cheaper, greener alternative for cement ...

    As Kriven explains, a motive for finding a replacement like geopolymer for traditional Portland cement is environmental: Portland cement production requires a tremendous amount of energy to heat and convert the raw materials (at 1450°C), and can generate nearly one ton of CO 2 for every ton of processed cement.

  • Cement Manufacturing Process - Civil Engineering

    Stage of Cement Manufacture. There are six main stages of cement manufacturing process. Stage 1 Raw Material Extraction/Quarry. The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches.

  • Alternative raw material - Cement, concrete, aggregates
