    There are certain methods to remove the delaminated concrete, and then formwork is to be fixe. After that, the application of repair material like a dry pack, and wet pack, shotcrete, is carried out if reinforcement is not removed while fixing the pipe.

    You can try one other method also, by fixing plate bonding in the beam on the bottom to enhance the flexural strength, you will have to rest the plate on the bricks, and for that, you will have to remove the top layer of the brick. You also may need to provide scaffolding if you are altering the load-bearing wall. As it is a load-bearing structure, if any alteration is done in the load-bearing wall, it should be done with the consultation of a structural engineer.

    CaO.        <1.2

    SiO.          <1.0

    Fe2O3.     <0.3

    Cr2O7.     >3

    ZrO2.        >3

    Properties:

    Cold crushing strength >180 MPa

    porosity.        >15%

    Bulk density. > 3.25 g/cm^3

    Modulus of rupture. > 9.5 MPa

    Applications:

    1. It is fire-resistant properties
    2. Strength in the range between 70 to 100 MPa.
    3. High resistance against thermal shocks
    4. Resistance against slag erosion

    Hi Manasa,

    Welcome to Theconstructor.org

    This is a detailed answer on Direct and Indirect Expense/cost is described

    Expenses are amounts paid for goods or services purchased. They can either be directly or indirectly related to the core business operations. Type of cost and Timing at which it is incurred by the business frames the critical points of difference between direct and indirect expenses.

    Examples of direct and indirect expenses – Rent, light, salaries, wages, sales, etc. Direct and indirect costs are defined and differentiated as follows;

    Direct Expenses

    Direct,” as the word suggests, are those expenses that are entirely related and assigned to the core business operations of a company. They are mainly related to purchases and production of goods/services. Direct expenses are a part of the prime cost or the cost of goods sold by a company.

    Direct expenses are directly related to the production of the product sold or service rendered. They may differ for different companies, such as manufacturing companies, construction companies, service companies, etc.

    Direct expenses are shown on the debit side of a trading account.

    Examples of Direct Expenses

    · Wages

    · Factory rent

    · Cost of raw material

    · Premises renting

    · Fuel

    · Carriage inwards

    Indirect Expenses

    Unlike direct, indirect expenses are not directly related and assigned to the core business operations. Indirect expenses are necessary to keep the business up and running, but they can’t be directly related to the core revenue-generating products or services’ cost.

    Just like direct expenses, indirect expenses can also be different for different types of organizations. These are usually shared costs among different departments/segments within the firm.

    Indirect expenses are shown on the debit side of an income statement.

    Examples of Indirect Expenses

    · Salaries

    · Telephone bills

    · Printing & stationery

    · Legal & Accounting charges

    · Carriage outwards

    Generally the most appropriate size of aggregate used in RCC structure is 20mm. It gives more strength to the structure.

    Plasticizers are generally colorless liquids which are relatively nonvolatile. In other words, plasticizer is a substance that is added to the material to make it softer and more flexible. Plasticizers are commonly added to polymers such as plastics and rubbers, to facilitate the handling of the raw materials during fabrication.

    The purpose and usage of plasticizer are as follows ;

    • Used to convert a rigid plastic into a soft, flexible and elastic material.
    • Increases the plasticity nature of the mix to decrease its viscosity.
    • It imparts flexibility to resin and minimizes film cracking
    • It is also used as an air entraining agent.
    • It decreases the water/cement ratio and gives high strength.
    • It helps in improvement of workability of the mix.
