11/7/2011 · An updated version of the ACPA brochure "Why Pump Concrete" has now been added to the ACPA's educational and promotional library of materials and is available to its membership. Featuring some of the latest and the most innovative pumping equipment in the marketplace, the brochure details the benefits and multitude of placing options available to meet the needs of today's concrete
When concrete is pumped, it is separated from the pump line walls by a lubricating layer of water, cement and sand. Naturally, the concrete mix must be suitable for its particular application, but it must also contain enough water for the mix to move easily through the reducers, bends and hoses found in most basic pipeline setups.
Pumping is a very reliable, efficient and cost effective means of placing concrete. Sometimes a pump is the only way of placing concrete in a required location, such as a high rise building, or large slabs where the chutes of the concrete truck cannot reach the desired location.
6/8/2015 · The first of these, which can be seen above, is 'Why Pump Concrete', a 1990s 10 minute justification of using concrete pumps for building projects. All the concepts still apply today, but what is interesting is that the advantages of pumping concrete needed to be pointed out, indicating they were not so self evident back then as they would seem today.
21/1/2014 · Advantages of Concrete Pumping over Chute Delivery. To make chute delivery work, the concrete mix must be very wet or watered-down. This hurts the strength of the concrete. Using the same aggregate to cement ratios in a mix, the dryer mix that a concrete pump can deliver can produce concrete that withstands 3000 PSI.
1/11/2020 · A concrete pump can be designed to use alternative sources of energy. It can use petrol, diesel, or other energy sources. This eliminates any cases of downtime in case one source of energy is unavailable. You can also choose from a wide range of mixers that
Testing concrete as discharged from the pump alongside the pump will require the most critical boom configuration that will cause the highest loss of air content. If concrete at a higher air content (to compensate for this loss) is placed at a less critical, more horizontal boom configuration, the concrete placed in the structure will be at a high air content and lower strength.

28/9/2010 · Concrete pumps help mixer dispatchers by providing more predictable unloading times. The steady flow from the pump can also increase finisher productivity due to the lack of interruptions and delays. Unlike human resources, pumps show up for work on time without complaint and never take a …

11/6/2019 · Concrete pumps can pump large volumes of concrete as quickly as a truck mixer can discharge the concrete. Many pumps can pump 30 to 100 cubic metres of concrete per hour. And this quick, precise placement method also ensures a quality pour. The setup time for concrete pumps is also very fast—arriving on site and pumping concrete within the hour.
Concrete without admixtures and of high cement content, over about 460 kg/m 3 are liable to prove difficult to pump, because of high friction between the concrete and the pipeline. Cement contents below 270 to 320 kg/m 3 depending upon the proportion of the aggregate may also prove difficult to pump because of segregation within the pipe line.
