### What is Pumped Concrete? Types of Concrete Pumps and Selection

Selecting a Suitable Concrete Pump Concrete pumps are selected based on two primary parameters, the maximum desired volumetric output of concrete per hour and the peak pumping pressure, p. A nominal output of 30 m3/h is considered sufficient for routine concreting operations related to most civil engineering applications.

Vacuum technology is based upon the creation of an environment in which a process (thin film deposition, electron beam welding, etc.) can be carried out. This normally implies that one remove air from a system to some acceptable sub atmospheric pressure by the use of some type of vacuum pumping equipment.

Concrete Ingredients Calculation. For Cement, Sand and Coarse Aggregate. This is a Volumetric Calculation. Assuming we need 2 m 3 of concrete for M20 Concrete Mix, (Mix Ratio, M20 = 1 : 1.5 : 3) Total Part of the Concrete = 1+1.5+3 = 5.5 Parts. Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume

Concrete mix estimation. Our mix-on-site concrete calculation is based on batching by volume (Large construction sites employ batching by weight which is more exact). You can also estimate the quantity of sand and gravel required by weight; Simply multiply the volumetric quantity of sand and gravel with 1400 kg/m 3 (bulk density of sand) and

Pressure surges are abrupt increases in operating pressure in force mains which typically occur during pump start-up and shut-off. Pressure surges may have negative effects on force main integrity but can be reduced by proper pump station and pipeline design. DESIGN CRITERIA Force main design is typically integrated with lift station design.

The first form calculates the pressure or friction loss along a given length of pipeline with a specified inside diameter. The second form calculates the minimum pipe size to limit pressure loss to a specified value. Additional friction pressure losses occur due to fittings. These losses in-effect add extra additional length to the total pipeline.
