Is 456 concrete?

456-2000 IS Plain and Reinforced Concrete-Code of Practice is an Indian Standard code of practice for plain and reinforced concrete general structural application. It contains a wealth of information about the many features of concrete. It is divided into five parts and eight annexures: Section 1: Introduction; Section 2: General requirements; Sections 3 to 5: Specific requirements for common types of structures; Sections 6 to 9: Special treatments for specific applications; Annexure A: General provisions relating to reinforcement; Annexure B: General provisions relating to joints in concrete structures; Annexure C: General provisions relating to materials other than cement; Annexure D: General provisions relating to forms; Annexure E: General provisions relating to testing; Annexure F: General provisions relating to drawings and specifications.

The latest edition was published in 2000. It replaces all previous editions of the Code from its first publication in 1955 up to and including the 1995 edition. The 2000 edition includes new requirements for energy conservation in buildings using concrete, changes to the definitions of certain terms, and corrections to errors found in the 1995 edition.

In India, the code is published by the Indian Institute of Concrete Technology (IICT). The code is used by engineers while designing structures made of concrete.

An engineer will usually use a combination of standards to design any given concrete structure.

Is 1343 a prestressed concrete code?

Table 12 of the Indian standard code of practice for prestressed concrete design, IS 1343, 1980, was for the design of unbonded post-tensioned concrete with varied l/d ratios and reinforcement indexes. This table has been replaced by Table 14 which includes provisions for both bonded and unbonded post-tensioning.

The original version of this document contained errors in its calculation of reinforcement requirements for varying l/d ratios. These have since been corrected in version 3.1.

IS 1343 is currently under revision and will be replaced by BS 1363: 2008 when it is published.

Where is plain concrete used?

Plain concrete is often used for the construction of pavements, pathways, and structures in places where high tensile strength is not required. High fortitude To make high-strength concrete, reduce the water-cement ratio to less than 0.35. Concrete that has a water-cement ratio of 0.30 or lower is considered "plastic" rather than "tough" and will break down more quickly if it is exposed to moisture.

Plain concrete is also used as an inexpensive replacement for stone or wood in building projects. The concrete can be colored any color you want by adding various pigments to the mix. It can also be stained with liquids such as dyes or paints and then polished with a tool called a "concrete polisher" to give it a worn look like stone or wood.

Plain concrete is used in many different types of structures including driveways, patios, and sidewalks. It is easy to maintain, durable, and flexible enough to be used in most climates.

The most common type of plain concrete is called "brown slab". This concrete looks like dry mud and is used for playgrounds, patio floors, and other areas where aesthetics are important but durability isn't necessary. The brown color comes from sand added to the mixture. The concrete on your driveway is usually another color - gray or black - and it's called "aggregate concrete".
