BASF Construction Chemicals In the test method, a sample of freshly mixed concrete is placed in a cylindrical mold without tamping or vibration. Print 1 2 3 4 5 page sstarting from page current page.
Your opinions and contributions are welcome. After 15 minutes, the mold is separated into three sections representing the top, middle, and bottom of the cylinder. According to ACI 237r-7, the slump flow should not differ self-consolidatig more than 2 in.
The test method is suitable for use in the laboratory and in the field. If you like to setup a quick demo, let us know at support madcad. Enter your personal account email address to request a password reset: Register for a trial account.
A nonmandatory appendix of ASTM C provides a procedure for a relative measurement of flow rate, viscosity, and stability. View directory of all issues. A difference of less than 1 in.
ASTM Test Methods for Self-Consolidating Concrete
The information in this document is expected to inform concrete producers, users, and specifiers of SCC of known practices and processes. This self-consloidating contains the current state of knowledge with respect to SCC. The retained aggregate from each section is weighed and the static segregation calculated as the difference between the bottom and top sections divided by the average weight.
The slump flow is the average of the two diameters. The J-Ring is placed outside the slump cone so that the concrete flows through the legs of the ring when the cone is lifted. Copyright Compu-tecture, Inc. Land Use and Development. There were no books found for the applied search filters.
The following ASTM standard test methods have been developed to address these fresh self-consolidwting properties. This book also exists in the following packages FORMAT Single User Subscription Site License Subscription BOOKS All Books PACKAGES All Packages EDITION to PUBLISHER.
Remember me for one month. Please login to your authorized staff account to use this feature.
The slump flow with and without the J-Ring is measured. Use of Fly Ash in Concrete. The slump flow test allows a comparison of the lateral flow and filling potential of different SCC mixtures. Are you sure you want to empty self-conwolidating cart? The flow rate is determined by measuring the time it takes for the outer edge of the concrete to reach a diameter of 20 in. No items in cart.

A difference greater than 2 in. After spreading ceases, two orthogonal diameters of the concrete 237r-0 are measured. The slump flow test can be used in production to assess the consistency of SCC. Click here to download full list of books.

Enter your account email address to request a password reset: A common range of slump flow for SCC is 18 to 30 in. A sample of freshly mixed concrete is placed in the cone in one lift without tamping or vibration. Manual of Concrete Practice Part 2 The flow rate is influenced by the concrete’s viscosity. Guide for Concrete Inspection. The stability can be observed by visually examining the concrete patty for evidence of segregation.
237R-07 Self-Consolidating Concrete
ACI has over 95 chaptersstudent chapters, and nearly 20, members spanning over countries. Each section is removed individually and the concrete in the top and bottom sections washed over a No. The test method is a laboratory procedure to determine the potential static segregation.
The mold is lifted and the concrete allowed to spread. Self-consolidating concrete SCC must self-coonsolidating the ability to flow under its own weight, to pass reinforcing bars or other self-condolidating without segregation, and not segregate during or after casting.
