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.

Best Mix for Pumped Concrete | JLC Online

Mar 01, 2010 · Generally speaking, the maximum slump for a pumped mix is about 6 inches. 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

Concrete Pumping - How to Pump Cement - Concrete Network

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.

Ready Mix Concrete Ordering Tips

Jan 23, 2019 · Strength . One of the most important factors before ordering ready-mix concrete is knowing the required compressive strength. Typically, reinforced concrete ranging between 3,500 to 4,000 psi is used on footing and slabs on grade; between 3,500 to 5,000 psi on suspended slabs, beams and girders; and walls and columns normally require between 3,000 to 5,000 psi.
