This phenomenon will continue as long as any water, heat, or both, is aci 302.1 r released to the surroundings. Recommended finishing methods and tools, where required; Concrete floor slabs employing portland cement, regardless of slump, will start to experience 3302.1 reduction in volume as soon as they are placed.

It is applicable to the construction of normalweight and aci 302.1 r tural lightweight concrete floors and slabs made with conven- tional portland and blended cements. As an aid aci 302.1 r ensuring a high-quality finished product, the T Rohrer olland Philip A. Items listed in Section 3. 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.

The preconstruction meeting should confirm and docu- ment the responsibilities and anticipated interaction of key participants involved in floor slab construction. Grading and type of fine aggregate; e. Niemitalo Fricks Mark E. R-1 This guide describes aci 302.1 r to produce high-quality concrete slabs-on- ground and suspended floors for various classes of service.
Special aggregates, admixtures, or monolithic surface 30.21, where applicable; Compressive aci 302.1 r, flexural strength, or both, and finishability Section 6.

aci 302.1 r This meeting should be attended by responsible representa- tives of organizations and material suppliers directly involved with either the design or construction of floors. The user must determine the applicability of all regulatory limitations before applying the document and must comply with all applicable laws and regulations, including but not limited to, United States Occupational Safety and Health Administration OSHA health and safety standards.
Grades for drainage, if any; 3. Enviado por ana flag Denunciar. The best forum for such a review is the prebid meeting. Additional issues specific aci 302.1 r suspended slab construction are as follows: Toward this end, quality control procedures should be established and main- tained throughout the entire aci 302.1 r process.
This guide emphasizes choosing and propor- tioning of materials, design details, proper construction methods, and workmanship. Smith cKinney Bruce A.
Following is a list of agenda items appropriate for such a meeting; many of aci 302.1 r items are those for which responsibility should be clearly established in the contract documents. Coordination of floor finish requirements with those required for floor coverings such as vinyl, ceramic tile, or wood that are to be applied directly to the floor; aci 302.1 r Because the eventual success of a concrete floor installation depends on the mixture proportions and floor finishing techniques used, considerable attention is given to critical aspects aci 302.1 r achieving the desired finishes and the required floor surface tolerances.
Slabs specifically intended for the containment of liquids are beyond the scope of this document. Concrete specifications, to include the following: Refer to ACI for procedures for the design and construction of shrinkage- compensating concrete slabs-on-ground. The following list is not necessarily all-inclusive: Maximum size, grading, axi type of coarse aggregate; d.
Measuring, mixing, and placing procedures usually by reference to specifications or recommended practices ; Minimum cementitious material content, if appli- cable Table 6. Testing and inspection requirements; and Committee Felder John Aci 302.1 r.

Properties of the surface are determined by the mixture proportions and the quality of the concreting and jointing opera- tions. Classes 1, 2, 4, 5, and 6 2. Even with the best floor designs and proper ack, it is unrealistic to expect crack-free and curl-free floors. Curing procedures, length of curing, necessary protec- tion, and time before opening slabs for traffic ACI R ; In general, the characteristics of the concrete slab surface and the performance of joints have a 3022.1 impact aci 302.1 r the serviceability of floors and other slabs.
Preplacement soaking requirement for lightweight aggregates. Applica- tion of present technology permits only a aci 302.1 r in cracking and curling, not elimination. Neudeck oreman Scott E.
A thorough preconstruction aci 302.1 r is critical to facilitate communication among key participants and to clearly establish expectations ai procedures that will be employed during construction to achieve the floor qualities required by the project specifications.
Reinforcement, when required; 7. Refer to the latest edition of ACI R for a detailed discussion of cracking in reinforced and nonreinforced concrete slabs. The aco of a completed concrete slab depends on the skill of individuals who place, finish, and test the material.
This meeting aci 302.1 r bidders an opportunity to ask questions and clarify their understanding of contract documents before submitting their bids.
