In December, a SANY ultra-high pressure trailer pump successfully reached a record height of 380 m in pumping concrete consisting of C130 manufactured sand in Guiyang, China.
C130 manufactured sand is the strongest concrete in the world, with a compressive strength of 149.6 MPa which far exceeds that of granite. To put it simpler, each square meter of a concrete member needs to bear 1,5000 t, a total weight of 3,000 adult African elephants.
As supertall skyscrapers, long-span buildings and specially shaped architecture are becoming increasingly popular, improvements need to be made in the strength, durability and reliability of concrete material, which necessitates the application of C130.
However, the pumpability of concrete declines as its strength increases, which means that C130 is much harder to pump compared to ordinary material.
Committed to changing the world, SANY constantly pushes the limits with ever-evolving technologies and products.
