IVAC SOLUTIONS: Concrete and Aggregate Pumping Services

Feb 01, 1973 · The properties of fine aggregate (sand) are more important in the design of pumpable concrete mixes than the properties of coarse aggregate. When combined with the cement and water, fine aggregate provides the fluid (mortar) which conveys the large solids (coarse aggregate) in suspension, thus making a mix pumpable.

Jul 18, 2018 · Pumping Concrete Components. Concrete is a material composed of various aggregates bonded together with a cement paste that hardens over time. The strength and durability of reinforced concrete enables engineers to design and complete massive projects. The IVAC PV250 & PV500 can pump and place mixed concrete exactly where it is needed on the

Mix Design for Pumpable Concrete | Materials | Concrete

This property can be achieved by adding more fine particles. Thus the proportion of fines is of prime importance. For pumpable concrete the contents of fines (cement + fine aggregate) 350 kg/m 3 to 400 kg/m 3 are considered necessary. This amount of fines is also necessary for maintaining lubricating film around the concrete plug to reduce wear and tear of the whole system.

CONCRETE 101

Slump is a measure of concrete consistency or fluidity. Consistency is the ability of freshly mixed concrete to flow. For given proportions of cement and aggregates (without admixtures), the higher the slump, the wetter the mix. Four-inch (4") slump is very common with normal weight concrete and is a good average slump for pumping.

Pumping of Concrete: System, Working and Problems

Fine Aggregate = 880 . We know that total fines less than 0.25 mm for pumpable concrete should be 350 to 400 kg per cubic metre of concrete. As the fine aggregate passes 0.3 mm sieve is 19%, the sand particles passing through 0.25 mm sieve = 19 x 25/30 = 16% app. ∴ Fine particles in sand = [(16 x 880)/100] = 140.8 = 141 kg. Cement content = 310
