7/5/2020 · Direct-acting concrete pumps: These pumps are direct-acting, horizontal piston pump with semi-rotary valves. Operation of these pumps are simple, the concrete is poured into the pump by gravity and partly by suction, due to the reciprocating motion of the
1/10/2013 · 1 Oct 13 An increase in the number of accident involving concrete pumps has prompted the production of new industry guidance on their safe use. The Good Practice Guide for the Safe Use of Concrete
Excavations: Remember the "one-to-one" rule when pumping concrete near an excavation or land that falls off steeply from the pump: For every foot of depth, position the pump at least one foot back from the edge. Pumps can be placed closer to the edge of a slope than to a vertical drop-off. For instance, on a one-to-one slope, the pump often
24/9/2020 · 1. The slump of the concrete should be within 50 mm to 100 mm. A slump of below 50 mm will be impossible and impractical to pump. A slump greater than 100 mm will increase the risk of segregation of the aggregates and will most likely cause blocking.

Concrete is generally used in two types of construction, i.e. plain concrete construction and reinforced concrete construction. In PCC, it is poured and casted without use of any reinforcement. This is used when the structural member is subjected only to the compressive forces and not bending.
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.
POLICY FOR USE OF CONCRETE PUMPS AND DISTRIBUTION MASTS Potential Risks: Limited space (outrigger deployment), mechanical problems, overturning or tipping over of the pump, failure of or breaking of the mast, reduced visibility for operator,
Pumping of concrete is economical if the quantity of concrete required is more than about 1150 m 3 or uninterrupted supply of concrete is needed over a long period as at the beginning of each period of pump ing the pipes have to be lubricated by mortar (at the rate of about 0.25 in 3 per 1000 m length of 150 mm diameter pipe) and also at the end of the operation considerable effort is needed
