Then we can obtain the required mix design for different grades of concrete. In this project, general mix proportion is providing us the general procedure for nay grade of concrete.

In the field of construction, concrete is the main material made up of different type of materials. The concrete is of different grades and each grade of concrete is useful for different properties and place.

Generally these are two type of concrete, 1. By Adopting 1. By designing the concrete mix, concrete is called as Design Mix Concrete.

By adopting the concrete mix, concrete is called as Nominal Mix Concrete. Conversion Conversion Emoticon Emoticon.

IS 456: Plain and Reinforced Concrete - Code of Practice

About IS This standard was first published in under the title 'Code of practice for plain and reinforced concrete for general building construction' and subsequently revised in The code was further revised in and published under modified title 'Code of practice for plain and reinforced concrete', thus enlarging the scope of use of this code to structures other than general building construction also.

The third revision was published in , and it included limit state approach to design. Construction joints should comply with IS It is recommended to clean out laitance and cement slurry by using wire brush on the surface of joint immediately after initial setting of concrete and to clean out the same immediately thereafter.

The prepared surface should be in a clean saturated surface dry condition when fresh concrete is placed, against it. In the case of construction joints at locations where the previous pour has been cast against shuttering the recommended method of obtaining a rough surface for the previously poured concrete is to expose the aggregate with a high pressure water jet or any other appropriate means.

Fresh concrete should be thoroughly vibrated near construction joints so that mortar from the new concrete flows between large aggregates and develop proper bond with old concrete. Where high shear resistance is required at the construction joints, shear keys may be-provided. Sprayed curing membranes and release agents should be thoroughly removed from joint surfaces.

The period of curing shall not be less than 10 days for concrete exposed to dry and hot weather conditions. In the case of concrete where mineral admixtures or blended cements are used, it is recommended that above minimumperiods may be extended to 14 days.

Such compounds shall be applied to all exposed surfaces of the concrete as soon as possible after the concrete has set.

Hence, constant and strict supervision of all the items of the construction is necessary during the progress of the work, including the proportioning and mixing of the concrete. Supervision is also of extreme importance to check the reinforcement and its placing before being covered. Curing is the process of preventing the loss of moisture from the concrete whilst maintaining a satisfactory temperature regime. The prevention of moisture loss from the concrete is particularly important if the-watercement ratio is low, if the cement has a high rate of strength development, if the concrete contains granulated blast furnace slag or pulverised fuel ash.

The curing regime should also prevent the development of high temperature gradients within the concrete. Supersulphated cement concrete is seriously affected by inadequate curing and the surface has to be kept moist for at least seven days.

The water-cement ratio shall not exceed 0.

If the charge in the tremie is lost while depositing, the tremie shall be raised above the concrete surface, and unless sealed by a check valve, it shall be re-plugged at the top end, as at the beginning, before refilling for depositing concrete. Coffer-dams or forms in still water shall be sufficiently tight to prevent loss of mortar through the walls. De-watering by pumping shall not be done while concrete is being placed or until 24 h thereafter.

Otherwise it may be leached and become segregated. Concrete shall be deposited, continuously until it is brought to the required height.

While depositing, the top surface shall be kept as nearly level as possible and the formation of seams avoided.

The methods to be used for depositing concrete under water shall be one of the following: c Drop bottom bucket -The top of the bucket shall be covered with a canvas flap.

The bottom doors shall open freely downward and outward when tripped.Part 3: The higher the chloride content, or if subsequently exposed to warm moist conditions, the greater the risk of corrosion. Within the concrete mass, different types of metal in contact should be avoided to ensure that bimetal corrosion does not take place. A mumber subjected to lesser load than 0. Aggregate Size Contents in Table 5 8.

However, these clauses may also be applied to flanged beams by substituting b, for b, in which case they are generally conservative; therefore specialist literature may be referred to. Torsional moment Wall thickness Shear force Total load Wind load Distributed Distributed load per unit area dead load per unit area. In this code it has been assumed that the design of plain and reinforced cement concrete work is entrusted to a qualified engineer and that the execution of cement concrete work is carried out under the direction of a qualified and experienced supervisor.

Oto 2. The accuracy of these methods, in part, is determined by the degree of correlation between strength and the physical quality measured by the non-destructive tests.
