Its short setting time reduces its diffusion ability and injectability, and the strength of its double liquid stone body is low due to its poor compatibility with sodium silicate [26]. Polymer chemical materials have high injectability, however, they are polluting environment in general, and some...
In contrast to CG5, the variant counts of CG8b remain relatively constant over time (Table 1). The observations from the three additional time points reinforce the previous notion that a generalist lifestyle under fluctuating environmental conditions constrains the accumulation of population-level ...
Ensuring the durability of concrete throughout its intended service life within a structure is of the utmost significance. The durability of a structure may be hindered by either internal agents present within the concrete or external pollutants originating from the environment, such as action due to...
In this process, the conjugate continuous fiber may has a conjugate structure, in a cross section, comprising an ultra-fine fiber component composed of the water-insoluble thermoplastic resin, and a water-soluble thermoplastic resin for separating or splitting the component into a plurality of ...

Naturally occurring montmorillonite is easily swellable, plastic and flexible, but its crystal structure is not uniform since it includes various impurities and ion-exchange with other cations is not completely carried out as co-ordination or adsorption of sodium is very complicated. Thus, an alkali ...
This fine fiber can be made in the form of an improved multi-layer microfiltration media structure. The fine fiber layers of the invention comprise a random distribution of fine fibers which can be bonded to form an interlocking net. Filtration performance is obtained largely as a result of ...
