Concrete Mixing & Delivery

Concrete Truck Mixes Cement to Desired Propertis On-Site Including Small Jobs

This concrete delivery truck is able to mix dry ingredients with water and other additives as needed, delivering the exact quantity of concrete needed for small or large concrete pours. The system eliminates several concerns faced by concrete contractors, masons, and concrete delivery companies including concrete wastage, having to spill un-used concrete at a dump-site to protect the concrete mixer truck, and the ability to custom-adjust the concrete slump at the job site. This system also permits addition of treatments for frost protection when pouring in cold weather.

The mason used the concrete delivery on-site mix truck system shown above for his larger pour of the foundation for front entry stairs of the home shown in our photograph above. During that part of the job the mason's own cement mixing equipment rested, rusting peacefully in Poughkeepsie.

Next, for the smaller quantities of mortar mix used to construct the stone-faced steps for this same entry stair the mason put his own cement mixer to work, shown in detail in the photographs just below.

Cement mixer & hand pouring a stone & concrete parking area, Guanajuato, Mexico

At below left we see the traditional precision measurement of concrete ingredients. The worker is filling a 5-gallon plastic bucket with sand. At below right you see the mixing blades in the interior of the empty portable cement mixing machine. Washing out the cement mixer interior at the end of the day's use is essential if it's to remain usable.

Below we see operating details of this portable cement mixer: its gasoline engine and the mixing tub gears that the engine and its drive gear will operate to rotate the mixing vessel.

Below the workers are dumping sand and gravel into the cement mixer. Along with portland cement and water (the large barrell in the right of this photo) all of the key ingredients for mixing concrete are in place.

At above right the hand-poured concrete is rough-smoothed - the worker is using a shovel. When this steel wire-reinforced concrete slab was set the workers set a finished surface of flat stones - piled in the forground in our photograph. The slab is to be used to park a motor home or other vehicles visiting the property.

In preparation for a new parking lot the concrete curbs are poured within the forms that you see thorughout these photos. Those U-shaped re-bars are simply used to hold the forms in place during pour and set of the concrete, speeding concrete form installation and removal.

Cement pump, continuous pre-mixed cement delivery, large pour - placement, Poughkeepsie NY

These photographs show the concrete construction of the bottom floor slab of the new "Bridge Building" - a new 80,000 sq.ft. science center being constructed in 2013-2014 at Vassar College in Poughkeepsie, New York. The building was designed by Ennead Architects.

Above you can see the enormous reach of the concrete pumping truck across the job site and into the building's basement. A continuous stream of concrete trucks at the job site kept the pour continuous (below).

Below is the concrete pump delivery point and at below right, workers managing the concrete placement through the mesh of steel reinforcing re-bar. Because the pour occured in cold weather, the design included a specification for re-bar temperature as well as other details.

At least thirty truckloads of concrete were delivered to this job, timed to arrange continuously to permit a continuous pour.
