Cement production, however, also generates most of concrete's emissions: in fact, a 2016 study found that cement accounts for around 7% of all greenhouse gas emissions worldwide. 2 Cement begins as crushed minerals that are heated in a kiln to make what is called "clinker."
He observed that 15% partial replacement was the optimum dosage. To address the cement/concrete industry's environmental and economic challenges, Malik et al. (2013) used waste glass as a partial replacement for fine aggregates (sand) in concrete. Several samples were made by replacing sand with glass contents of 10%, 20%, 30%, …

Precast Concrete also is known as "prefabricated" is a construction product produced by casting concrete in a reusable mold or "form" which is then cured in a controlled environment, transported to the construction site and lifted into place. In contrast, standard concrete is poured into site-specific forms and cured on site. produced in plants ...
Concrete Design & Production Concrete is a mixture of two components: aggregates and paste. The paste, comprised of cement and water, binds the aggregates (usually sand and gravel or crushed stone) into a rocklike mass as the paste hardens.

The Portland cement manufacturing process is representative of all types of cement. limestone and clay are the main raw materials of cement making, the cement raw materials will be processed into a raw meal by crushing, batching, grinding.
In contrast, standard concrete is poured into site-specific forms and cured on site. produced in plants in a location away from the construction site. These components are manufactured by industrial methods based on mass production in order to build a large number of buildings in a short time at low cost. Only members can download files.
