    You should use PSC cement as this type of cement has various speciality than ordinary cement.

    PSC is the portland slag cement and it is also a type of supplementary cementatious material but it works on hydraulic activy. The material used is directly react with water and from cementetious compounds but the property of the concrete can be increased if the blend of slag and cement is made.

    PSC can reduce the construction cost, better strength and durability and many more.

    Hi, sunlight is the best source of light and energy. So to use effectively, the placing of windows and other openings and reflective surfaces matters a lot.

    As a civil engineer, it’s our aim to maximize the comfort of the user and reduce the energy consumption for saving electricity.

    The design of the building should be like this the rays of sunlight it will be scattered from the wall and reflect and cover a maximum area of the house. There will be no direct sunlight on polar sites of the walls that are north facing and south-facing. Providing large Windows is a good option to maximize the use of natural sources of light.

    In the present scenario, translucent concrete is been used as concrete which transfers the light in various commercial buildings to reduce the use of artificial electricity. This is a great gift from nanotechnology.

    the position of lights inside the room must be at the middle of the wall and not at the corners so that lights spread 180 degrees.

The constituent of this type of flooring is cement, admixture, down 10mm coloured/white chips mixed with required water of around 35-50 mm thick on rcc/pcc surface. It is done through panel system making by glass trip/aluminium strip. Flotter can be used to surface smooth.

    IPS floor can be used for all types of floors.

    nikeetasharma Guru

    CBR test is done in construction materials laboratories to evaluate the strength of soil subgrades and base course materials. The purpose of soil sample soaked in water for 7days is to find out the strength of the sample after soaking continuously in water. The effective CBR should be 75% .

    The usual sizes of tiles available in the market are 20*20 cm, 20*10 cm, 15*15 cm. The thickness of these tiles are 15mm and 20 mm. But nowadays large size of tiles are preferred over small tiles. Thankyou.

    Steel reinforcing bars are used to enhance the tensile strength of concrete though concrete is weak in tension, and its because both have the same coefficient of thermal expansion. Also, structural steel is used as such to construct steel buildings, which is more easier in erection and is having less strength to weight ratio compared to concrete. Also steel have 100% scrap value.

    MILD STEEL REINFORCING BARS

    The mild steel bars are smooth and round in shape having diameter ranges from 6mm to 50mm used for small scale construction works.

    Mild steel is also known as low carbon steel having 0.1% to 0.25% of carbon. But mild steel is not considered as an alloy steel though it doesn’t contain other elements in it compared to different steel varieties. As carbon content increases, ultimate strength and hardness will increase, but ductility and toughness decreases. Though mild steel contains very little carbon, it is ductile and weldable but having low strength. Also, mild steel is highly prone to corrosion.

    HIGH YIELD STRENGTH DEFORMED BARS

    High yield strength deformed bars (HYSD) are manufactured under heat treatment followed by either heat rolled or cold twisted for shaping.

    HYSD bars moderately resistant to corrosion and the manufacturing process itself cause surface flaws in it. It is heavily weighted, and its transportation cost is high. Residual stress is high and tensile stress is low in HYSD bars that cause deformation.

    THERMO-MECHANICALLY TREATED BARS

    TMT bars are having much more advantages than hysd bars and nowadays hysd bars are not using.

    TMT bars are having a hardened outer core and soft inner core. These bars are passed through water after they get hot rolled, which makes the surface more firm, and the inner core stays warmer itself. Hence core became more ductile, and no deformation process employed like in hysd makes it more strengthened. TMT bars are having soft ferrite-pearlite core with a hard martensitic rim.TMT bars help to reduce steel consumption to 8 to 11% compared to hysd bars. TMT bars are having more corrosion resistive property and is highly flexible than hysd bars. It is highly earthquake resistant with high tensile strength and low residual strength. TMT bars can absorb about 400 to 600°C of heat and highly fire-resistant.

    COLD TWISTED DEFORMED BARS

    The specifications related to CTD bars are provided in IS: 1786–1985. They are commonly known as TOR steel bars.

    TOR is a kind of high adherence steel. TOR bars have surface deformation formed by twisting the steel after lengthening. This imparts high yield strength to steel and furnishes legitimate proper bondage with concrete.TOR is a type of hysd steel, where the steel bars, subsequent to experiencing the required heat treatment process, are cold twisted and distorted.

    QUENCHED AND SELF TEMPERED STEEL

    These are very much similar to TMT bars where annealing is the process which is not conducted for QST steel manufacturing. These have adequate quality and malleability. QST steel bars are also having the same cross-sectional material of soft ferrite-pearlite core with a hard martensitic rim as that of TMT bars.
