TL;DR: In this paper, a laboratory study demonstrates that high volume, 45% by mass replacement of portland cement (OPC) with 30% finely-ground basaltic ash from Saudi Arabia (NP) and 15% limestone powder (LS) produces concrete with good workability, high 28-day compressive strength (39 MPa), excellent one year strength (57 MPa) and very high resistance to chloride penetration.

TL;DR: Jackson et al. as discussed by the authors showed that Altobermorite also occurs in the leached perimeters of feldspar fragments, zeolitized pumice vesicles, and in situ phillipsite fabrics in relict pores.

TL;DR: In this paper, an adiabatic thermal model of the 10 m 2 by 5.7 m Baianus Sinus breakwater from heat evolved through hydration of lime and formation of C-A-S-H suggests maximum temperatures of 85 to 97 °C.

TL;DR: In this article, geologic and geophysical data and mechanical models support a laccolithic origin for the central magma chambers underlying the domes, but these data alone do not rule out the possibility of a stock at depth.
