When cement is cured at temperatures above 250°F,Patchen (1960)notes that a loss of compressive strength is observed, called strength retrogression. This strength retrogression is linked to an increase in permeability, which is undesirable for zonal isolation. He notes that no strength retrogression...
Sandro Campos Amico, in Green Sustainable Process for Chemical and Environmental Engineering and Science, 2023 Abstract Supplementary cementitious materials, like stalk fibers, have been attracting attention in order to mitigate the consumption of fossil fuels, emission of greenhouse gases, changes in ...
expansion in the presence of moisture. Since they are highly waterproof, expansive cements are used for sealing joints between prefabricated rein-forced-concrete structural members, for reliable waterproofing in certain hydraulic engineering structures, and for manufacturing of reinforced concrete pressure ...
which enables the plant to reduce energy consumption by using exactly the amount of coal fuel required to meet the specific heating values required to process materials in the kiln and mill. Kiln feed material with high chemistry variations requires more fuel to properly react and more energy at...
Kiln feed material with high chemistry variations requires more fuel to properly react and more energy at the finish mill to grind over-reacted clinker.

The present paper renewedly expounds upon the characteristics of the 3D lightweight structure of beetle forewings and notes that two biomimetic structures (models) that have appeared in recent years do not comply with these characteristics based on a comparison of the structures of the biological pr...
Notes 1. The cluster of water-filled sinkholes atop dissolving evaporites and locally known as “Hell’s Kettles” (Lat 54.492655, Long −1.567459) located to the south of Darlington, UK, formed in 1179 AD via a catastrophic collapse of the landsurface. A twelfth century annalist describes...

Mechanical properties and durability of cement-based materials are largely affected by pore structures. This paper provides an overview of several experimental techniques to characterize pore size distribution and specific surface area, with focus on pores in calcium silicate hydrates. The reviewed experime...
