Commercial Flooring Glossary
Diluted salts that are carried to the surface of a concrete subfloor by water coming up from the ground below. These salts may cause installation failure of resilient flooring by destroying the adhesive bond. They can work their way up through tile joints and sheet goods' seams. In dry concrete, normal surface alkalinity on a pH scale is 9 or less.

Fault Analysis and Solution of Loader TECHNICAL SOLUTIONS
2 Brake failure Fault phenomena: When the loader is running, it can't slow down and stop when braking. Causes of failure: 1) The brake pressure is insufficient to drive the piston action of the brake. 2) Brake valve failure, piston jam or compensation hole and air hole blockage, can not produce enough air pressure.
IOP Conference Series: Materials Science and Engineering
Two-way reinforced concrete slabs are common in use in reinforced concrete buildings due to geometrically arrangement of columns suggested by architects who prefer a symmetric distribution of columns in their plans. Elastic theory is usually used for analysis of concrete slabs.
COMPRESSIVE STRENGTH OF SELF COMPACTING CONCRETE
The compressive strength is calculated by the failure load divided with the cross sectional area resisting the load and reported mega pascals (MPa). Concrete hardens and acquires strength as it hydrates. This process occurs rapidly at first and slows down as time goes by, it continues over a long period of time.
2020-04-09 · Concrete is strong in compression, as the aggregate efficiently carries the compression load.However, it is weak in tension as the cement holding the aggregate in place can crack, allowing the structure to fail. Reinforced concrete adds either steel reinforcing bars, steel fibers, aramid fibers, carbon fibers, glass fibers, or plastic fibers to carry tensile loads.
