Piezoresistivity-Based Strain Sensing in Carbon Fiber-Reinforced Cement. The authors argue that when using carbon fiber-reinforced cement (152 mm [6 in.] specimens under compression) in the elastic regime, the four-probe electrical resistance measurement method is more effective than the two-probe method for piezoresistivity-based strain sensing since there is less strain amplitude variation ...

The electrical resistance, flexural strength, and microstructure of carbon fiber reinforced cement composites (CFRC) were improved greatly by adding water-redispersible latex powder. The electrical resistance of CFRC was investigated by two-probe method. The input range of CFRC based strain sensors was therefore increased, whereas electrical resistance was increased and remained in …

Fiber cement board are composed of cement, silica sand and wood pulp. Reinforced fiber cement products such as fiber cement board are manufactured using the 'Hatscheck Process'. The Hatsheck process was initially developed for the production of asbestos composites, but it is now used for the manufacture of non-asbestos, cellulose fiber reinforced cement composites.
