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.

Eco-Friendly Alternatives To Traditional Concrete

Jul 18, 2019 Posted on July 18, 2019. Concrete is a mixture of cement, gravel, sand, water and a range of aggregates. With about 10 billion tons of concrete produced every year, it is the most consumed substance in the world, second only to water.. It is also the world’s most widely used material for construction from bridges to large buildings, concrete forms the very foundation of our infrastructure.

Geopolymer: A cheaper, greener alternative for cement

Feb 09, 2010 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.

How concrete block is made material, manufacture, used

Raw Materials The concrete commonly used to make concrete blocks is a mixture of powdered portland cement, water, sand, and gravel. This produces a light gray block with a fine surface texture and a high compressive strength. A typical concrete block weighs 38-43 lb (17.2-19.5 kg). In general, the concrete mixture used for blocks has a higher
