Guide to Consolidation of Concrete in Congested Areas
|Publication Date:||1 January 1992|
Many concrete structures such as those with seismic provisions, post-tensioning, and high-strength concrete are difficult to consolidate because of congested areas within the formwork. This congestion can result in structural inadequacy and time-consuming and expensive remedial work.
Various techniques have been employed to alleviate this type of problem. This document presents an overview of the factors contributing to the problem, the consequences of inappropriate concrete procedures in these areas, and recommended practices to minimize the problem.
As a prerequisite to successful concreting in congested areas or difficult placing conditions, it is important that architects/engineers
