Several types of reactive filler such as Silica Fume or microsilica, metakaolin, work very well in mortar or concrete applications. Owes to secondary reaction with hydrated lime, reactive fillers can improve the long-term strength development and early strength at water immersion condition for various mortars which strength development are hindered by additives such as Redispersible Polymer Powder or Cellulose Ether. Some lightweight fillers like exfoliated vermiculite are also key ingredients for lightweight mortar, thermal insulation mortar or fireproof mortar based on cement or gypsum.

Meter with mechanical preset register
With printer which generates an imprinted record of the transaction
The positive displacement flow meter equipped with the mechanically actuated piston valve and the mechanical counter with ticket printer.
The mechanically actuated piston valves which are available in 2" throngh 4" sizes and are designed for mounting on the meter outlet to provide tight shutoff vith smooth and easy operation regardless of system line pressure. Valves may be manually operated or connected via a mechanical linkage to a preset counter on the meter for single stage closure, or two-srage closur to eliminate hydrarlic shock. Valves are indexable in 90° Increments for up, down, or side facing outlet.
