Pea Stone Pump Mix - Concrete Engineering general
Feb 03, 2005 · Pea Stone Pump Mix2. My firm has a general note disallowing pea stone pump mixes preferring larger aggregates and yet no one has been able to give me a good reason why. Most says it's intuitive that it's relatively difficult to achieve even a 4000psi mix with pea stone or that it has worse than average shrinkage characterstics.
Numerical Prediction on the Effects of the Coarse
Thus, depending on the coarse aggregate sizes, the properties of lubrication layer which is the major role facilitating concrete pumping, were numerically simulated using shear-induced particle

Best Mix for Pumped Concrete | JLC Online
Mar 01, 2010 · The ideal concrete mix for pumping typically contains air-entraining agents, a little extra sand (compared with a standard concrete mix), often some fly ash, and a well-graded aggregate blend. To make the concrete easier to pump and place as it comes out of the hose, many batch plants also add water-reducing admixtures — known as
Trailer Concrete Pumps - How to Pick the Best Pump
Pea-rock pumps, for example, are designed to pump cement-based mixtures containing a 1/2-inch top aggregate size, such as repair grouts, shotcrete, and self-leveling overlays. Other line pumps can handle higher-slump concretes containing larger coarse aggregate (3/4- to 1 1/2-inch rock). These models are better suited for placing concrete slabs
Trailer pump concrete and aggregate size relationship
Mar 15, 2018 · The relationship between the maximum size of the coarse aggregate and the diameter of the transfer pipe should be: The maximum aggregate size of the trailer pump concrete is limited by the minimum diameter of the conveying pipeline. The maximum diameter of the pebble should be less than 1/3; the maximum size of the crushed stone should be less
Concrete Pump Crashes into NJ Transit Overpass
Jul 18, 2012 · A concrete truck headed toward Main Street in Madison on Friday morning crashed into the New Jersey Transit overpass at Kings Road and Green Village Road, apparently chipping the overpass and leaking hydraulic fluid near a storm drain. The driver, 50-year-old Pine Bush, N.Y., resident Howard Fisher, was taken to Morristown Medical Center with minor injuries, police said.
Portable Concrete Pump - Portable Concrete Mixer and Pump
Choose a suitable concrete pump, so as not to select a concrete pump with a pumping pressure that does not meet the requirements, causing the pump to block. The size of the burst pipe and the conveying pipe should be selected according to the requirements of coarse aggregates, so as to avoid improper selection and blockage of the pipe.

Principle of mix design for pumpable concrete | ACE Update
Sep 23, 2020 · The gradation of coarse aggregate plays an important part. Difficulties with pump have often been experienced when too large a proportion of coarse aggregate is used in an attempt to achieve economy by reducing the amount of cement; such mixes are also harsh and costly to finish. The grading of coarse aggregate should be as per IS: 383-1970.
