Origin of blocky aragonite cement in Cenozoic glaciomarine …
A total of 42 sandstones that host intergranular cement were collected from the CIROS-1 core, located proximal to the terminus of Ferrar Glacier. Standard petrography, Raman spectroscopy and electron microprobe analysis reveal a prominent aragonite cement phase that occurs as a pore-filling blocky fabric throughout the core.

History of Portland Cement in the United States
On the other hand, portland cement is an artificial mixture of raw materials, has a calcination at a temperature above 2,000 degrees Fahrenheit, and purer raw materials were used than necessary for natural cements. The raw materials used in the manufacturing of portland cement at this time were cement rock, limestone, shale, and coal.

Nanogranular origin of concrete creep
Portland cement with water, sand, and aggregates, suffers from time-dependent deformation under load. This creep occurs at a rate that deteriorates the durability and truncates the lifespan of concrete structures. However, despite decades of research, the origin of concrete creep remains unknown. Here, we measure
On the origin of eigenstresses in lightweight aggregate concrete
Three types of composites were studied, all with a cement paste volume percentage of 66.7% and an aggregate volume percentage of 33.3%, but with different contents of glass spheres (NWAs) versus Liapor grains (LWAs) (see Table 2).The glass spheres had an average size of 5.91 ± 0.15 mm and a Young's modulus of 77 GPa and …

Origin of the thermoelectric behavior of steel fiber cement …
Carrier scattering dominates the origin of the Seebeck effect in steel fiber cement. The scattering sites include the fiber–matrix interface, which is like a pn junction, since the fiber and cement paste have opposite signs of the absolute thermoelectric power. The scattering results in positive and negative values of the absolute ...
