Best Practice Guidelines for Concrete Placement Planning, Field Testing, and Sample Collection Page 1 September 2014 1 EXECUTIVE SUMMARY Concrete is the most widely used construction material and can be used in almost any environment for a multitude of applications but successful concrete construction begins with careful planning.
7.1 Planning the Activity 7.1.1 Before concrete placement begins, a detailed activity plan must be developed and reviewed with the crew. This plan should deal with every aspect of the pour(s) from start to finish in order identifying all hazards and factors to complete the work. Some safety items to consider when planning a pour are:
Jan 01, 2022· ACI Concrete Terminology. To provide durable concrete, it should be free of segregation and the mortar should be in close contact with the coarse aggregate, reinforcement, and any adjacent faces to which it is to be bonded. Concrete should be deposited, as nearly as practicable, in its final position. Placement of concrete is accomplished with buckets, hoppers, …
Jobsite Considerations: Planning •Prepare for Ambient Conditions - Monitor weather to increase awareness of potential issues at/during placement •Schedule concrete placements to avoid extreme weather, such as at night or during favorable weather conditions. •Assure equipment and placement crew size is adequate for the jobFile Size: 2MB
In slab construction, placing should be started along the perimeter at one end of the work with each batch placed against previously dispatched concrete. Do not dump the concrete in separate piles and then level and work them together; nor should it be deposited in large piles and moved horizontally into final position. Consolidation
Oct 01, 2017· Pre-planning is essential for a successful placement. Prior to placement to concrete refer to the Fox Blocks Installation Checklist 1.02.01 Refer to Technical Bulletin 1.06.01 Concrete Design and Placement The American Concrete Institute (ACI) does not directly address the height of concrete placement. Installation Checklist
temperature surrounding the concrete between 50oF and 100oF. Place Hi-Lo thermometers on the concrete surface at locations directed by the RCE. Monitor concrete temperatures for a period of 4 days after the concrete is placed. Additional monitoring locations may be added by the contractor if deemed appropriate to ensure concrete protection.
🕑 Reading time: 1 minuteConcrete pouring is a crucial process which not only needs properly qualified persons but also considerable focus and concentrations.

Step 1 - Site Work. Before concrete can be poured, the site needs to be prepared to reduce the chance of heaving from expansive soils and frost. On small projects, use hand to tools to clear the area of all grass, rocks, trees, shrubs, and old concrete, exposing bare earth. Earth moving equipment speeds up the process, especially for large pours.
