The TARA Vibrator provides a unique mechanism suspended on leather belts, which allows for the vibration to be controlled by adjustable tie rods, depending on the type of cement mix, availability of materials and water-cement ratio.

This mix requires a water-cement ratio between 0.45 and 0.5.

· In order to seal the pore system of the concrete matrix several methods were tested (eg use of higher proportion of fines, lower water-cement ratio, etc.), and interesting results were achieved by adding small beads of wax to the fresh mortar.

Hence, the correct water-cement ratio is important for strength development.

· Normal range for amount of water used to mix each 50 kg bag of cement is between 20 liters and 30 liters (94 lb. bag of cement is between 4.5 gal. and 7 gal.) · The water-tightness of concrete depends primarily on the water-cement ratio and the length of moist curing.

Chapter 7 1980

If the mix is too stiff, add small amounts of water and cement, maintaining the proper water-cement ratio, until the mix is workable.

However, the practical upper limit of water-cement ratio for ferrocement depends on the acceptable value of permeability, since it is clear from Figure 21 that ferrocement made from mortar with a water-cement ratio of more than about 0.6 has a very high permeability.
