4 21 (hereinafter referred to as CIS 21), which is the STANDARD for ready-mixed concrete certification, was developed by the working group on ready-mixed concrete, with the assistance of Construction Industry Development Board Malaysia (CIDB). CIDB acted in the capacity of moderator and facilitator for the Working Group throughout the development process of this STANDARD . This CIS, mainly based on MS 523: Part 1:2005, was developed specifically for ready-mixed concrete as a basis for ready-mixed concrete producers in ensuring that their ready-mixed concrete plant, production and production control, transportation and delivery are certified independently by a certification body recognised by CIDB. Compliance with the content of this document does not in itself confer immunity from legal obligations. 1 1. Introduction MS 523: Part 1:2005, which is a full adoption of EN 206-1:20001, provides a platform for upgrading and enhancing the quality of ready-mixed concrete to a higher level through a product-conformity approach by providing a mechanism for the product to be independently certified by a recognised certification body.

5 MS 523: Part 1:2005 placed greater responsibility to the producer who shall be responsible for the conformity of ready-mixed concrete according to the concrete specification. Note 1: EN 206-1:2000 has been superseded by EN 206:2013. However, MS 523: Part 1: 2005 still refers to EN 206-1:2000 as MS 523: Part 1: 2005 and it is yet to be amended. MS 523: Part 1: 2005 is supported by two complimentary Malaysian Standards - MS 523-2:2011: the method of specifying and as a guidance for the specifier and MS 523-3:2010: a specification for constituent materials and concrete. These two complimentary standards, which include the Malaysian experience, provide a good link for specifiers and users to the MS 523: Part1: 2005. MS 523: Part 1:2005 covers both site-mixed concrete and ready-mixed concrete. The quality of site-mixed concrete is very much dependent on the contractor and the project supervisor while ready-mixed concrete, on the producer.

6 However, to date, there is no specific Malaysian STANDARD for ready-mixed concrete that addresses and assists Malaysian producers to readily understand and adopt MS 523: Part 1:2005. Thus, CIS 21 was put together to provide a clear direction for ready-mixed concrete producers in complying with the requirements of MS 523: Part 1:2005. Additional requirements are included, which takes into consideration the knowledge and experience gained by the Malaysian concrete industry. In general, Annex C of MS 523: Part 1:2005 have made provisions for assessment, surveillance and certification for concrete and they are applicable for ready-mixed concrete. CIS 21, which is specifically titled as Ready-Mixed Concrete:Production, Conformity, Transportation And Delivery Criteria For Producers is dedicated to ready-mixed concrete only. It is to be used for product certification with new and redefined terms that are highlighted in Additional requirements are also provided in as to supplement the provision in MS 523: Part 1:2005.

7 2 New and redefined terms Several existing terms are redefined1 and new2 definitions, in comparison with the definitions in Clause 3, MS 523: Part 1:2005, have been established in CIS 21, befitting its application base on the information in MS 523 and other information available from other sources. These terms may assists producers better, in order to comply with the applicable requirements of MS 523: Part 1 :2005. They are as follows: i. Ready-mixed concrete (redefined, see ), ii. Ready-mixed concrete plant (new, see ), iii. Production control (new, see ), iv. Production control system (new, see ), v. Wet batching (new, see ), vi. Dry batching (new, see ), vii. Plant mixer (new, see ), viii. Initial production (new, see ), ix. Continuous production (new, see ), x. Initial assessment (new, see ), xi. Product certification (new, ) Note 1: These terms are already in use and have been defined in MS 523: Part 1:2005.

8 Note 2: These terms are already in use in MS 523: Part 1:2005, but not distinctly defined. Additional requirements Additional requirements have been included in CIS 21, in comparison to MS 523. These are as follows: i. Introduction of Type 1 and Type 2 batching plant (see ) ii. Legal requirement for the producer (see ) iii. Technical personnel (see ) iv. Quality management system (see ) v. Certification by CIDB recognised CB (see ) vi. Certificate (see ) vii. Identification (see ) and Signage (see ) 3 2. Scope The scope of CIS 21 is for ready-mixed concrete produced by any ready-mixed concrete plants ( , plants may be located on the construction site or off-site), producing concrete for structural and non-structural use, including those used in casting of precast concrete products. CIS 21 covers two types of batching plants1, which are: Type 1 - Wet batching plant2 (W) Type 2 - Dry batching Plant3 (D) Note 1: A typical schematic diagram of wet and dry batching plant is highlighted in Appendix A.

9 Note 2: In wet batching, the primary mixing of the concrete is performed in a plant mixer, and the secondary mixing is done in the truck mixer for maintaining the concrete in homogenous state before the concrete is discharged from the truck mixer. Note 3: In dry batching, the primary mixing of the concrete is performed in a truck mixer, and the secondary mixing is done in the truck mixer for maintaining the concrete in homogenous state before the concrete is discharged from the truck mixer. This publication includes production and production control, conformity, transportation of concrete to the point of delivery, and delivery. CIS 21 is published for producers, specifiers, users, inspection bodies, certification bodies, regulating authorities and other interested parties as the basis for compliance on ways ready-mixed concrete is produced, transported to the point of delivery, delivered under a documented production control system and production control procedures.

10 The producer shall be responsible for the evaluation of conformity of concrete to specified requirements. The ready-mixed concrete shall comply with applicable specified requirements of MS 523: Part 1:2005, MS 523-2:2011 and MS 523-3:2010. 4 3.
