Implementation of self-consolidating concrete in caisson

Sep 01, 2012 · Both types of concrete were placed into "wet hole" conditions using a tremie pipe, which was fed using a pump system. No slurry was used for concrete placement, but a removable steel casing was used for the drilled shaft portion of the construction. Download : Download full-size image; Fig. 8.

Recommendations for Pumping Self-Consolidating Concrete

• The entire section of self-consolidating concrete should be pumped in one pour, without stopping. This procedure will help the concrete already in the formwork from losing slump flow before the formwork is completely filled. PRIOR TO PUMPING • Ensure that the concrete pump intended for use is capable of pumping self-consolidating concrete with either 6 mm (1/4 inch) aggregate (MS-S6 SCC) or 10 mm …

Self Consolidating Concrete - Sika

Concrete can be placed by pump or tremie directly into areas covered by water. Sikament®-100 SC maintains the concrete matrix integrity during high slump placements and reduces washout from the surface during curing. Reduce or eliminate dewatering costs associated with underwater construction. Concrete is easy to pump and flows readily into

Using self-consolidating concrete in vertical and overhead applications has become an accepted and proven concrete repair method. Based on the orientation of the repair, pumping self-consolidating concrete can be the required method of placement for this material. However, pumping can also be the preferred method of application,

:: Self Consolidating High Performance Concrete :: SCC

Self-Consolidating ConcreteDelivers Efficiency, Beauty, Savings and More. Self-consolidating concrete, also known as self-compacting concrete (SCC), is a highly flowable, non-segregating concrete that spreads into place, fills formwork, and encapsulates even the most congested reinforcement, all without any mechanical vibration.

Height Limits on Concrete Free Fall| Concrete Construction

May 01, 1991 · The stream of the concrete shouldn't be separated by permitting it to fall freely over rods, spacers, reinforcement, or other embedded materials. If forms are sufficiently open and clear so that the concrete isn't disturbed in a vertical fall into place, direct discharge without the use of hoppers, trunks, or chutes is usually desirable.

Self Consolidating Concrete (SCC) — What, why, & how

Self consolidating concrete (SCC), also known as self compacting concrete, is a highly flowable, non-segregating concrete that can spread into place, fill the formwork and encapsulate the reinforcement without any mechanical consolidation. The flowability of SCC is measured in terms of spread when using a modified version of the slump test

Concrete pumping and its effect on the air void system

Jul 05, 2018 · Pumping is the most utilized concrete placement technique on construction sites around the globe. Despite being used since the 1960s, a large portion of the knowledge related to the understanding of the concrete pumping process—especially with a focus on the effect of pumping on the concrete air void system—was generated through experience, and thus creating a need for a research …

May 22, 2017 · Placement typically starts at the farthest point from the pump and proceeds back towards the pump, following a zig-zag pattern across the narrowest dimension. This enables workers to place SLU in widths of just a few inches at a time, or several feet at a time, while maintaining a "wet edge" and more continuity in the SLU layer.
