Concrete with a relatively low water content can be readily molded into an unlimited ac of shapes, making it a highly versatile and economical construction material. The paired values stated 309-05 inch-pound units and hard SI units are usually not exact equivalents. Mixture proportioning is described in ACI For a listing of and access to all product errata, visit the Errata page. Reference to this document shall not be made in contract documents. Combining values from the two systems may result in nonconformance with this guide.
Consolidation is the process of inducing a closer arrangement of 309e-05 solid particles in freshly mixed concrete or mortar during placement by the reduction of voids, usually by vibration, centrifugation spinningrodding, spading, tamping, or some combination of these actions. These items are not eligible for return. Consolidation is the process of removing entrapped air from freshly placed concrete.
Equipment and methods are now available for fast and efficient consolidation of concrete over a wide range of placing conditions. Size px x x x x We need your help! Guide to Mass Concrete Reapproved Please fill this form, we will try to respond as soon as possible.
These methods are infrequently used. The Institute shall not be liable for any loss or damage arising therefrom. PDF free access to members. Please choose a product format.
Some form of vibration is usually employed. This document is intended for the use of individuals who are competent to evaluate the significance and limitations of its content and recommendations and who will accept responsibility for the application of the material it contains.
If adequate consolidation is not provided for these stiffer mixtures, the strength of the in-place concrete decreases rapidly.

The full and complete returned product will be accepted if returned within 60 days of receipt and in salable condition.
Therefore, each system is to be used independently of the other. This guide includes information on the mechanism of consolidation and gives recommendations on equipment, characteristics, and procedures for various classes of construction.
Manual of Concrete Inspection. By using certain chemical admixtures ACI Some form of vibration is usually employed. Consolidation is the process of removing entrapped air from freshly placed concrete.
It will have 309-05 strength, high permeability, and poor resistance to deterioration.

ACI 309R-05 – Guide for Consolidation of Concrete
The American Concrete Institute disclaims any and all responsibility for the stated principles. We are a non-profit group that run this website to share documents. As the water content of the concrete is reduced, concrete strength, permeability, and other desirable properties improve, provided that the concrete is properly consolidated. Stiffer mixtures require greater effort to achieve proper consolidation.
Avi various consistency tests have been discussed by NevilleVollickand Ferraris ACI 309r0-5 Reports, Guides, Standard Practices, and Commentaries are intended for guidance in planning, designing, executing, and inspecting construction. When good consolidation practices are combined with good formwork and good form release agents, concrete surfaces have a highly pleasing appearance Fig.
