Cement plays a pivotal role in the development and maintenance of urban infrastructure. The substance in question finds application in the production of concrete and mortar, serving the purpose of fortifying the structural integrity of infrastructure through the process of binding individual building components together.
This seminar is designed for production managers, plant managers, general managers, and production engineers with at least one year of experience in the cement industry. Individual responsibility is vital for reaching usable technical conclusions and presenting their results to obtain a course certificate.
At the heart of Titan America's operations is the production of low-carbon cement, construction aggregates, a broad range of high-performance ready-mix concrete products, and concrete block. We also play a pivotal role in beneficiating, processing and distributing fly ash for industrial applications, underlining our commitment to sustainable ...
The avoided concrete production, which included the production of Portland cement (PC) and the use of recycled aggregate, contributed to a reduction of 349.9 kg CO 2-eq/FU. Similar to the agricultural soil application, the WH biochar preparation and the carbon content sequestration contributed 263.5 and − 481.3 kg CO 2-eq/FU, respectively.
In this review, we discuss the role of microbes in influencing the various properties of concrete such as compressive strength, flexural strength and tensile strength by reducing …

The production of heat causes an increase in the thermal energy of the system and thus a decrease in its overall enthalpy. b) The forward reaction is not favored by entropy because the reaction results in a decrease in the number of moles of gas molecules (CO 2 ) and an increase in the number of moles of solid molecules (CaO).
In the manufacture of concrete units the three important materials used are cement, aggregates and water. Constant care in the proper selection and gradation of the aggregate, assurance that the cement meets or exceeds standard specifications and a supply of clean, pure mixing water are absolutely essential to the economical production of units of uniformly high quality.
Cement production reportedly accounts for the largest global materials flow, thus achieving global environmental sustainability through responsible consumption and production is central to the sustainable development scenario. But even that China, the world's largest carbon emitter and largest cement producer, is under-studied.
But Sant said now that the process has been proven, it could, in time, be scaled up to production levels. If cement manufacturers continue to operate as they currently do, and if proposed carbon taxes in the U.S. and other nations are eventually enacted, cement production would be much more expensive than it is now.

Even if cement is a well-consolidated material, the chemistry of cement (and the chemistry inside cement) remains very complex and still non-obvious.
However, the 19th and 20th centuries ushered in modern brick and concrete homes, high-rises, roads and highways. Subsequently, Aspdin's portland cement alone couldn't meet the needs of these modern-day concrete structures. Therefore, the industry had to modify portland cement, resulting in the following cement types: Nonhydraulic cement:
Cambridge Electric Cement Cambridge Electric Cement is a novel approach to the electrification of cement that integrates cement production with the production of steel in an electric arc furnace (EAF). The process is premised on the fact that spent cement powder from concrete waste has a similar composition to the slag used in the EAF process.
Although cement comprises only around 10% of the total weight of concrete, it contributes to approximately 70% of the greenhouse gas emissions associated with concrete production. Cement production has a typical carbon footprint between 600 and 900 kg of carbon dioxide (CO 2) per ton of cement and is responsible for 7% of all global CO 2 emissions.

Employing mineral carbonation products as a cementitious substitute could reduce the cement industry's greenhouse gas (GHG) emissions. However, a transition toward low-emission cement requires financially competitive cement production at standardized product specifications. Aiming to tackle this challenge, we modeled and optimized a direct mineral carbonation …
Concrete is in desperate need of revitalisation in the 21st century due to growing durability, maintenance and environmental concerns. Improving the cement within concrete is an essential part of addressing these concerns. While Portland cement manufacture and use can still undergo slight environmental improvements, great opportunities lie in the utilisation of cements …

Many building materials today constitute a significant anthropogenic source of carbon dioxide. Concrete, in particular, is responsible for more than 8% of global carbon emission, with 30 billion tons produced each year and its demand ever growing [30,31]. The biggest culprit behind this carbon footprint lies in the production of Portland cement .
