SONO-ES Concrete: T3/22 probe with TECANAT Installation tube and SONO-ES transducer. All traditional procedures to measure moisture in hardened concrete are strongly dependent on disturbance variables like temperature and volatile salinity. Long-term stability of many sensors like humidity sensors is also not guaranteed. In contrast to previous methods TRIME-TDR stands out by its non-destructive, ...

Hercul-EZ is a proprietary additive that is used in conjunction with bentonite based drilling muds. With proper formulation, the system will produce a unique drilling fluid with excellent shear thinning characteristics. At low shear or at rest, the fluid will gel and allow for suspension of large cuttings, yet thins immediately under pumping conditions. At rest, HERCUL-EZ fluid looks and behaves ...

Manufactured by Sipag Bisaltabased in ITALY
Drilling muds play a fundamental role in the construction of special foundations, since they are key to ensure digging stability, seal borehole walls through cake formation, as well as suspend drill cuttings and fines. Drilling muds are normally prepared by mixing bentonite with water. In some instances, bentonite is replaced with polymers. ...

Manufactured by Jining Fortune Biotech Co.,Ltd.based in CHINA
CMC & PAC can be used as fluid loss reducer or viscosifier in drilling fluids. The function of CMC is to reduce the fluid loss as much as possible through forming low permeability, flexible, thin and compact filtration cake on borehole wall. Used as thickening agent, suspension agent and plugging ...
