Generally speaking, polypropylene filament geotextile is often used in drainage systems, filtration, isolation and other engineering projects because it has good water permeability. Polyester filament geotextiles are usually used in engineering projects that require higher strength and durability, such as large dams, civil engineering, ...
Biaxial geogrid reinforcement for roads is a geotechnical material made of plastic materials such as HDPE, which has high tensile strength and tensile breaking strength. Biaxial geogrid undergoes tensile processing during the manufacturing process, giving it high tensile strength in both transverse and longitudinal directions, which improves its overall mechanical properties. Biaxial geogrid ...
The equipment can not only be used in construction projects, it can also be used in mining, metallurgy, sewage treatment, tunnel construction, and other projects. What is a mortar sprayer? The mortar spraying machine is a kind of coating equipment, which mainly disperses the mortar into a mist and then sprays it on the surface of the object. ...

This paper focuses on the studies of the correlation between the ventilation and pollutant removal over idealised two–dimensional urban street canyons using wind tunnel experiments in the Department of Mechanical Engineering, The University of Hong Kong. To construct street canyon models of different building–height–to–street–width (aspect) ratios, movable ...
In this paper fabrication, optimisation and application aspects of complementary Multiple-Gate Tunnelling FETs (MuGTFETs) are presented. Tunnelling FETs (TFETs) are realised in a state-of-the-art low-power multi-gate CMOS technology. n- and p-type tunnelling currents are observed within a single device structure. ...
Molecular engineering of low-dimensional materials exploiting controlled self-assembly and positioning of individual atoms or molecules at surfaces opens up new pathways to control matter at the nanoscale. ...
During the production process it is streamed through pips to the production tunnel where it is mixed with water. This procedure produces an immediate chemical reaction that causing the mixture to swell, and eventually creating the foam. ...
