To limit cracks that may develop in reinforced concrete around mild steel bars due to stretching of bars and some lose of bond under load it is common to use deformed bars that have projecting ribs or are twisted to improve the bond with concrete These bars are produced in sections from 6 mm to 50 mm dia In addition the strength of bonds of deformed bars calculated should be 40 to 80 %

As per Clause 304 7 of IRC 21-1987 permissible shear stresses for M20 concrete i) Without shear reinforcement = 0 34 MP a ii) With shear reinforcement = 0 07 x 20 = 1 40 MP a – Hence the section will be safe with shear reinforcement Shear Reinforcement for Outer Girder Bent up bars Shear resistance of 2 – 28 Φ bent up bars in double system = 2x2x615x200x 0 707 = 3 47 800 N

Every concrete contractor must have a complete set of tools to get the job done Since concrete waits for no one the right tools can make the difference between a successful pour and a potential disaster Most of the essential tools are basic and do not require a significant investment

The deterioration of concrete structures in the last few decades calls for effective methods for condition evaluation and maintenance This resulted in development of several nondestructive testing (NDT) techniques for monitoring civil infrastructures NDT methods have been used for more than three decades for monitoring concrete structures now it has been recognized that NDT plays an

Flexural Analysis of Reinforced Concrete Beams IIT Academic Resource Center Structural Concrete •It's everywhere •Beams are one of the most common structural components •Parking ramps high rises bridges Analysis versus Design •Analysis •Determining the strength of a beam with given dimensions and reinforcement •Design •Creating a beam that will carry a specified load

Concrete mix proportions are designed to achieve it desired properties it's placing compaction and curing are also critical to realize potential of a concrete as an end product Mixing transporting and handling of concrete should be cautiously synchronized with placing and finishing operations Concrete should not be deposited more rapidly than it can be spread

To have proper check for uniform spraying of chemical graduated containers shall be used Proper check should be kept that specified quantity of chemical is used for the required areas during the operation 2 4 TIME OF APPLICATION Soil treatment shall start when foundation trenches and pits are ready to take lean concrete in foundations Laying of lean concrete shall start when chemical

In the present study strength parameters of steel fibers reinforced concrete (SFRC) were investigated Their load carrying capacity and deflection characteristics were also evaluated and compared with those of Plain Cement Concrete (PCC) Three different concrete mixes were chosen One is of PCC and two mixes are of SFRC with fibers content of 4% and 8% of cement weight

The use of post-tensioned reinforcement to construct floor slabs can result in thinner concrete sections and/or longer spans between supports Designers commonly take advantage of this method to produce buildings and structures with clear open spaces allowing more architectural freedom Reducing the thickness of each structural floor in a building can reduce the total weight of the structure

Properties of Cement Concrete The cement concrete possesses the following important properties It possesses a high compressive strength It is a corrosion resistance material and atmospheric agent has no appreciable effect on it It hardens with age the process of hardening continues for a long time after the concrete has attained sufficient strength

Concrete quality control is not just during the manufacturing of the concrete It becomes very important after proper placement Proper curing of laid concrete is very important If not then water that is for concrete bonding will evaporate and henceforth concrete strength drops down from the specified value
