and whereas the attached publication of the Bureau of Indian Standards is of particular interest IS (): Guidelines for concrete mix design. Concrete mix design is always aimed to achieve required workability while in fresh state of concrete, strength under the state of loading and durability with the passage of time. Bureau of Indian Standards in this direction has recently revised the guidelines for mix proportioning. IS (Reaffirmed. ). RECOMMENDED GUIDELINES FOR Thia publication ir protected under the Indiaa Cofryrilif Act (XIV of ) and.

Indian standard method: IS ▻ The Bureau of Indian Standards, recommended a set of procedure for design of concrete mix mainly based on the. Abstract: The main aim of this project is to provide the gen- eral mix design for any grade of concrete, so that, this proj- ect contains the mix design for M40 grade.

An uncorrected copy, or prepublication, is an uncorrected proof of the book. We publish prepublications to facilitate timely access to the committee's findings. The final version of this book has not been published yet. You can pre-order a copy of the book and we will send it to you when it becomes available. We will not charge you for the book until it ships.

The design is carried out for a desired compressive strength and workability of concrete. This standard does not include the design of concrete mixes for flexural strength or when gap-graded aggregates or various admixtures and pozzolana are to be used. Appendix control to be expected. A provides guidance regarding the different degrees ofquaIity depending upon the infrastructure and practices adopted at 8.

In such case. Since different cements and aggregates of different maximtim size. IS I lo NOTE -The method described in A pendix B involving determination of compressive strength of concrete cubes cureB by accelerated method. TMod Aucsrsfh 40 a: UXETE 10 3. IS I Part III Specific gravity. Aggregates should be used in saturated surface dry SSD condition. The cement content per unit volume of concrete may be calculatrd from the free water-cement ratio see 3.

The surface water and percent watrr absorption of aggregates shall be determined according to IS: If otherwise. On the other hand. The cement content so calculated shall minimum cement content for the requirements greater of the two values adopted YSpecification for coarse and fine aggregates revision. Siarsea - Coarse aggregates of different sizes should be combined in suitable proportions so as to result in an overall grading conforming to Table 2 of IS: Using the relationship so obtained between the compressive strength and water-cement ratio.

The mix shall be carefully observed for freedom from segregation and bleeding and its If the measured workability of Trial Mix No. For these two additional Trial Mixes No. MIXES 4. The coarse aggregate used should conform to IS: The quantity of materials for each trial shall be sufficient for at least three mm size cube concrete specimens and concrete required to carry out workability test according to IS: Quantities of materials worked out in accordance with 3.

The procedure for trial mixes is explained by an illustrative example in Appendix D. The masses of the various for concrete of a particular batch size may be calculated. Workability of the Trial Mix No. The concrete mix proportions shall. Mix No.

In addition. If the size and special requirement of the work so warrant.
