The magnitude of the testing load or loads shall be determined in accordance with Paragraph A5. If colour control is specified it shall be checked prior to the surface treatment. The structural design of formwork shall comply with Section 4.
Stacked materials—construction materials such as formwork components, bricks, reinforcement, which temporarily loads either the formwork assembly or the previously placed concrete. The project documentation shall be consistent with the achievement of the required colour. Plumb shall be measured from a point mm from the top of the vertical surface to a point mm from the bottom.
Limitations on the use of the permanent structure for the restraint of formwork. Where the opposite faces are of different classes then the face with the higher quality shall take precedence in the checking.

It provides information on the loading to formworm considered in the design of the formwork assembly see Clause 4. Form face—that part of the form which comes direct contact with the plastic concrete.
Appearance including surface finish. In the absence of such specified minimum times, Table 5. Any limitations on the magnitude and locations of stacked materials and minimum concrete strength to be achieved prior to the stacking of materials.
It applies to— comcrete the surface finish of formed and stripped concrete surfaces; b the requirements for the project documentation related to surface finish as listed in Section 2; and c the provisions and use of test panels for both cast in situ concrete and precast concrete.
Built to close tolerances. Tolerances in AS take precedence where more stringent than those specified in this Section. Your consent to our cookies if you continue to use this website.

Supports ass bracing mentioned above are sometimes known as falsework. This Section does not apply to unformed concrete surfaces, or to the faces of concrete elements constructed fomrwork permanent formwork.
AS 3610.1-2010 Formwork for concrete
Straightness tolerance shall be expressed as the maximum distance by which any point on an edge of a unit may be from a straight line drawn through the extremities of the particular edge. Steel Unless the steel can be positively identified by brand marks or other distinguishing features as being of a particular grade, the yield strength shall be assumed to be fof more than MPa. Optical instruments, jig frames or string lines shall be used, as applicable.
These standards are developed through an open process of consultation and consensus, in which all interested parties are Licensed to Kaitlyn Caso on 19 Mar Stage II—during placement of concrete.
Element—portion of the permanent structure delineated by formed concrete faces, construction joints and the completed concrete surfaces, which is poured in one 36110 operation. The light conditions at the time of evaluation and the period of time after the stripping of the form before evaluation is carried out shall be consistent for all elements with similar requirements. Footing—part of the formwork or permanent structure in direct contact with, and transmitting load to, the supporting foundation.

Erection procedures shall not involve unsafe practices. No part of this work may be reproduced or copied in any form or by any means, electronic or mechanical, including photocopying, without the written permission of the formaork. The following requirements shall apply to the identification of materials: Second editi on Attention is drawn to the possibility of the manufacturer requiring more stringent accuracies than those specified in this Table.
For prestressed concrete units, this check includes the hog.

Whether deep revibration or external vibration can be used see Clause 4. Where live and other transient loads, and loads from stacked materials occur, both full and zero values of these loads shall be included to determine the most severe condition.
That a test report has been prepared in accordance with this Standard. Loads from currents, axial shortening, stacked tidal, wave shrinkage, etc. The value of prestress or post-tensioning strain hog and shortening is influenced by variation in material properties in a similar way to that of other permanent load effects see AS Excellent quality of edge and joint details Suitable uses Selected small elements.
For concrete of other colours or where the grey is not within the range of Figure B4, the project documentation shall contain a means of determining and recording the acceptable tonal range.
Surface undulations Surface undulations shall be ascertained by using two straightedges, a short one of mm and a long one of mm. I can act in opposite direction to G. Refer to Clause 3.
Silica fume has a marked effect on the properties of fresh concrete and is frequently used in conjunction with superplasticizers. Refer to See Figure 5. There shall be NO stacked materials on any of the floors.
