Not all the crude agglutinates are crushable into primary particles by beads-milling. The most reliable criterion for the crushability of crude detonation product is zeta-potential in aqueous suspension, which must be higher than +50mV or lower than -50mV as determined on a Zetasizer Nano-ZS (Malvern Instruments, England). We use fluffy, grey-coloured fine powder made by Guangzhou Panyu Guangda...

To solve the technical problems of slow construction progress, low mechanization and high risk shallow buried large cross-section tunnels in a complex urban environment, series spatial reticulated shell (SRS) support structures are developed this paper. Moreover, equipment multifunctional operation trolley is to install SRS arch, technology system prefabricated structure proposed for tunnel. Th...

A measurement campaign of particle number concentration and size distribution was conducted at urban (SYSU) suburban (Panyu) areas Guangzhou, South China, during 16 January to 3 February 2020 before the Chinese New Year (CNY) holiday. Average (PNC) 6.3 × 103 cm-3 9.7 cm-3, respectively, sites, indicating severe particulate matter (PM) pollution. The PNC in region influenced by monsoon land–sea ...
