WHY DO BRIDGES NEED PROTECTING?

http://www.applechemie.com


To improve the performance and durability of reinforced concrete surfaces on bridge structures, additional protection systems are frequently required, particularly in refurbishment situations. Typical concrete protection systems for bridges can be classified as hydrophobic impregnation, sealing impregnation, surface coatings, or corrosion inhibitors. These are designed for use in different situations or collectively in alternative combinations, to greatly reduce damage to the concrete surfaces and to stop or significantly reduce the rate of steel reinforcement corrosion. Thus preventing the even more significant structural damage, that would otherwise occur.


REQUIREMENTS

·         Protection against ingress of water, chloride and carbon dioxide
·         High resistance against UV radiation
·         Resistance against frost and wide temperature variations

Concrete Curing Compound

Curing is essential for the hydration of cement in concrete making. So, to maintain required moisture content, come precautions are applied. Concrete curing compound is a compound which helps to prevent the loss of moisture content from the concrete. So, concrete is properly cured which results the full development of strength of concrete. Types of Concrete Curing Compounds ·          Synthetic Resin Concrete Curing Compound Synthetic resins will seal the concrete by forming membrane. If we want to provide plastering, the membrane can be removed by washing it with hot water. ·          Acrylic Concrete Curing Compound Acrylic is made of polymers of acrylic acid. It also seals the concrete in good manner. It is having property of adhesion to the subsequent plaster. No need to wash the surface of acrylic with hot water if we want to provide plastering. ·      ...

Materials are used for road construction

Image
Road consist of basically 4 layers: Sub-grade: The sub-grade material should be clean and free from organic matter and should be able to be compacted by roller, to form stable sub-base. The material should have the following characteristics: ·          Well graded, uniformity coefficient (D60/D10) should not be less than 3. ·          Fraction passing sieve #200 shall not be greater than 2/3rd of the fraction passing sieve #40. ·          Should have a L.L not greater than 25%. ·          P.I not greater than 6 ·          CBR should not be less than 25. ·          In coarse grain, aggregate retained by #10 sieve, %age of wear shall not be greater than 5%. ·          The maximum dia...

DESIGN PROCEDURES FOR A BUILDING FOUNDATION

Good design must not only be safe but must aim to save construction costs, time and materials. The following procedures should help to achieve this and an ‘educated’ client will recognize the importance of funding this work with a realistic fee. 1. DECIDE THE LOCATION OF COLUMNS & FOUNDATION AND TYPE OF LOADS ACTING ON THEM On the building plan, the position of columns and load bearing walls should be marked, and any other induced loading's and bending moments. The loads should be classified into dead, imposed and wind loading's, giving the appropriate partial safety factors for these loads. 2. ESTIMATE ALLOWABLE BEARING PRESSURE OF SOIL USING GROUND INVESTIGATION REPORT From a study of the site ground investigation (if available), the strength of the soil at various depths or strata below foundation level should be studied, to determine the safe bearing capacity at various levels. These values – or presumed bearing values (from any standards or codes) in the...
