Stakeholders. The U.S. Life Cycle Inventory Database was developed collaboratively with a wide variety of partnerships. Some of these stakeholders helped to launch the database in 2001 and have contributed along the way.
The Urgency of Embodied Carbon and What You Can Do about
The most widely accepted method for assessing embodied carbon is whole-building life-cycle assessment (WBLCA), but other tools can supplement this as a first step. By replacing portland cement and using other carbon-reducing strategies, the team was able to cut the embodied carbon of the new Mexico City Airport project by 130 million kilograms.

The Greenhouse Gas Emission from Portland Cement Concrete
material production, concrete manufacture and pavement onsite construction. The GHG emissions of the three phases are analyzed by a life cycle inventory method. The CO2e is used to indicate the GHG emissions. The results show that for 1 km Portland cement concrete pavement construction, the total CO2e is 8215.31 tons.
Pavements Life Cycle Assessment (LCA) | Concrete
Life cycle assessment (LCA) considers all life-cycle phases from initial construction to demolition. For pavements, this includes the operation, maintenance, and end of life phases, and factors such as traffic delay, lighting demand, and future maintenance. CSHub models quantify environmental impacts across a pavement's life cycle from

Cement is one of the most widely used building materials in the world, with global cement production of 4.7billion metric tonnes (Mts) in (CEMBUREAU, ). The production of cement is an energy-intensive process with an estimated average thermal energy requirement of 3.4 GJ for 1 tonne clinker globally in (IEA, 2020b).

This book provides an updated state-of-the-art review on new developments in alkali-activation. The main binder of concrete, Portland cement, represents almost 80% of the total CO2 emissions of concrete which are about 6 to 7% of the Planet's total CO2 emissions. This is particularly serious in the current context of climate change and it could get even worse because the demand for Portland

Longest Life Cycle Longest Life Cycle With Minimal Maintenance. Concrete is one of the most durable construction products on earth. It's common to have masonry buildings with effective service lives of 50, 75, or even 100+ years. Likewise, concrete pavingstones offer similar extended life cycles - typically assumed to be 25 years or more.
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.
End of life LCA and embodied carbon data for common
The term 'embodied carbon' refers to the greenhouse gas emissions (expressed as carbon dioxide equivalents - CO 2 e) associated with a product or material during its life cycle.In recent years, the term has become synonymous with the term 'carbon footprint'. An embodied carbon or carbon footprint assessment is a subset of most Life Cycle Assessment (LCA) studies.
How Portland Cement is Made? Manufacturing Process of
Portland cement can be made by following two different processes - a dry one and a wet one. Joseph Aspdin first made portland cement in his kitchen stove in England in the 19th century. Lime and silica make up approximately 85% of portland cement. The materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore.

Cement Manufacturing Process Phase II: Proportioning, Blending & Grinding. The raw materials from quarry are now routed in plant laboratory where, they are analyzed and proper proportioning of limestone and clay are making possible before the beginning of grinding. Generally, limestone is 80% and remaining 20% is the clay.

New approach suggests path to emissions-free cement | MIT
Ordinary Portland cement, the most widely used standard variety, is made by grinding up limestone and then cooking it with sand and clay at high heat, which is produced by burning coal. The process produces carbon dioxide in two different ways: from the burning of the coal, and from gases released from the limestone during the heating.
