This paper introduces an experimental research about the influences of the curing type on accelerated carbonation, capillary water absorption and permeability of a range of different self-compacting lightweight concrete (SCLC) mixtures in comparison with those of chosen conventional vibrated lightweight concrete (LC) and self-compacting concrete (SCC).

Seven different concrete compositions are considered: four SCLC, two SCC and one LC mixtures.

The highest pressure recorded was 80% of hydrostatic pressure.

The wall and column were filled using a concrete pump and the material had a target slump flow of 28 in. during the time of the pour and the density of the material was 151 lb/ft3. Pressure exerted by SCC on formwork over time A large reconstruction project in Peoria, Illinois involved the construction of many new retaining walls.

Additionally, the highest pressure was reached long before the pour was finished.

It is also important to note that at some point in the pour additional concrete in the wall did not cause the pressure to rise, as evident by the maximum pressure occurring just over an hour into the pour which lasted 4 hours. Example of Results from University of Sherbrooke There are several means of studying formwork pressure with SCC in the laboratory.

A companion test column was fabricated which involved filling a 10.5-ft tall column.The column was filled at a rate of 60 ft/hr and the highest pressure measured one foot from the bottom.
