How to Calculate Concrete Formula | eHow

Apr 27, 2018 · When pouring concrete it is necessary to know how much concrete you need in order to purchase the appropriate amount. Concrete is sold by cubic yards, and one cubic yard of concrete will usually fill a slab measuring 36 inches in length, width and height. You can calculate the amount of concrete you need by employing a mathematical formula.

360R-06 Design of Slabs-on-Ground - NICFI

A new method is proposed to estimate pumping pressure based on concrete composition without experimental measurements. Previous studies show that the pumping pressure depends on the interface friction between concrete and the wall of the pumping pipes. This friction is determined by the thickness and the rheology of the boundary layer formed at the interface.

Concrete pump - Wikipedia

A concrete pump is a machine used for transferring liquid concrete by pumping.There are two types of concrete pumps. The first type of concrete pump is attached to a truck or longer units are on semi-trailers. It is known as a boom concrete pump because it uses a remote-controlled articulating robotic arm (called a boom) to place concrete accurately.. Boom pumps are used on most of the larger

8 ESSENTIAL QUALITY REQUIREMENTS OF PUMPED CONCRETE

Mar 21, 2016 · Concrete pumps can be either truck- or trailer mounted and range from small units, exerting pressures from 250 to 300 psi and outputs of 15 to 30 yd 3 /hr, to large units, exerting pressures of 1,000 psi and outputs up to 150 yd 3. The effective capacity of a pump depends not only on the pump itself but also on the complete system.
