Structure creation in earthen construction materials: information from dry soil mixtures

Christopher BECKETT, Charles AUGARDE

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 2,   Pages 151-159 doi: 10.1007/s11709-011-0109-7

Abstract: There is increasing interest in the use of earthen construction materials, such as rammed earth, due to their inherent sustainability. These materials have been used by man for thousands of years and some of the earliest examples can be found in China. Features of the structures of these materials arise from the means of production. In particular, in situ earthen construction materials exhibit strong anisotropy due to their layered nature. A more subtle structure effect arises from the way that the earth mixture is deposited. This paper reviews and discusses stratification effects in dry soil mixtures, including some original experimental work, and indicates some links between the features of the dry mixtures and earthen construction materials. Improved understanding of the physical processes in play will allow more accurate specification of these materials in the future, and hence spread their use.

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 2,   Pages 299-309 doi: 10.1007/s11705-020-1925-x

Abstract: the cobalt-time yield and turnover frequency passed from a maximum for catalyst with the Co average particlesize of 15 nm due to the synergetic effect of cobalt reducibility and particle size.methane selectivity decreases, whereas the C selectivity raises with the increasing of the cobalt particlesize, which can be explained by chain propagation in the primary chain growth reactions.
