In-situ evaluation of silane treated concrete cast using Zemdrain formwork liner at Dock street bridge, Belfast. Internal report to Du pont De Nemours, Luxembourg, Report No - TAS 139, June, 1992, p. 8, (Unpublished). Reddi, S.A. Permeable formwork for impermeable concrete.

Flow table with a grip and a hinge, 70 centimetres (28 in) square. In the American version of this test, the table is 10 inches (25 cm) diameter per ASTM C 230.; Abrams cone, open at the top and at the bottom - 30 centimetres (12 in) high, 17 centimetres (6.7 in) top diameter, 25 centimetres (9.8 in) base diameter.
"Form blowouts" also occur when under-designed formwork bends or breaks during the concrete pour (especially if filled with a high-pressure concrete pump). Consequences can vary from minor leaks, easily patched during the pour, to catastrophic form failure, even death. Concrete exerts less pressure against the forms as it hardens.
When selecting an anchor, consider the element formwork and the ease of placement and securing of the anchor prior and during the pouring of the concrete. For example, some of the anchors shown in figures 4-6, can be placed into thin wall elements as the anchor chair maintains the position relative to the element thickness .
Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). [1]
Newmark's Influence Chart is an illustration used to determine the vertical pressure at any point below a uniformly loaded flexible area of soil of any shape. This method, like others, was derived by integration of Boussinesq's equation for a point load.
Pumping concrete into aluminium concrete formwork in Mexico. A concrete pump is a machine used for transferring liquid concrete by pumping. There are different types of concrete pumps. A common type of concrete pump for large scale construction projects is known as a boom concrete pump, because it uses a remote-controlled articulating robotic ...
Cast-in-place concrete or Cast-in-situ concrete is a technology of construction of buildings where walls and slabs of the buildings are cast at the site in formwork. [1] This differs from precast concrete technology where slabs are cast elsewhere and then brought to the construction site and assembled. [ 2 ]
