As noted above, the structural element needs rebar to carry the tension in the reinforced concrete. So a footing needs rebar on the bottom, a simple beam or slab needs rebar on the bottom, etc. Rebar is also commonly used to help control concrete
20/3/2020 · Mixer and Pump Design: The main function of the pump is to transfer the concrete mixture from the mixer to the nozzle by means of the transmission hose. The pump must be designed with sufficient pumping power in view of the various concrete properties such as maximum aggregate grain size and water/cement ratio to deliver the concrete mix.
20/11/2014 · From mixer truck concrete will be poured to casting location by concrete pump or by bucket. The height from discharge position to casting level shall not be over 1.5m. On each concreting day and for each grade of concrete mix, samples shall be taken.
17/2/2016 · 1. Purpose of Concrete Compaction. Compaction significantly increases the ultimate strength of concrete and enhances the bond with reinforcement. It also increases the abrasion resistance and general durability of the concrete, decreases the permeability and helps to minimise its shrinkage and creep characteristics.
17/12/2011 · In general, it can be stated that any troubleshooting exercise must be undertaken with an open mind and a principle desire to find a solution and fix the pump, not simply to assign blame. Excellent observation and communication skills are necessary in all such endeavors. This article first appeared in Pumps & Systems, November 2008.

Methods of Placing of Concrete for Various Situations
The mixing occurred in a customized concrete mixer that was coupled with a progressing cavity pump. A volumetric blending system was used to merge the cement and water to produce the neat cement slurry, which was then pumped into a proprietary blending system where the preformed foam was introduced.
To pump Lytag® LWAC mixes requires the use of admixtures and an appropriate mix design to produce a semi-flowing concrete equivalent to BS 8500-1:2006 flow class F5 or target flow of 560–620mm. It is important that monitoring is carried out to ensure the
3. MCBP are mixers in specialised vehicles which carry concrete constituents to customer sites. At the site, the machinery mounted on the vehicle mixes the constituents to produce concrete of the quantity and specification required by the customer. They
At most of these plants, sand, aggregate, cement, and water are all gravity-fed from the weigh hopper into the mixer trucks. The concrete is mixed on the way to the site where the concrete is to be poured. At some of these plants, the concrete may also be
