    Let’s discuss some important precautions that we should keep in our mind while doing hand mixing of concrete. They are as follows ;

    • Hand mixing should be used for small concrete preparation
    • Hand mixing platform should be watertight and it should be impervious
    • Mixing platform should be of concrete platform or brick floor to avoid the addition of extra water in our concrete
    • Water should be added in some interval in concrete while hand mixing
    • Avoid large sizes of buckets for the measurement purpose
    • Labours should wear a mask to avoid some respiratory diseases

    Steps to follow for doing hand mixing of concrete :

    • Doing proper batching of all the ingredients of concrete and spread them evenly
    • Add cement with Sand and mix them for throughout
    • Mixing process should continue until we get the homogeneous colour
    • Then add coarse aggregate into it and again mix it appropriately
    • For mixing forward and backward movement of shovel have to be done
    • Then at the centre, one hollow circular space is formed for the addition of water
    • While doing hand mixing 5 to 10% of the extra amount of cement should be added
    • PPE( Personal Protective Equipment) should be wear by labour while doing hand mixing

    Potential Groundwater Impacts of Dewatering

    ·        Contamination

    Dewatering can cause the advancement of hydraulic gradients that are additionally fundamental for drawing out water towards wells. Dewatering close to a site with a background marked by contamination in groundwater can bring out hydraulic gradients that can convey the dirtied groundwater towards the dewatering framework and cause contamination. By and large, polluted water requires filtration. To evade this issue, the best technique is to introduce screen dividers and vertically separate regions utilizing bentonite seals.

    ·        Geotechnical Damage

    Dewatering can make the ground lose coherence; the result leads to ground settling. If the ground settling is vast, it can harm close by building and structures. When groundwater is removed from the soil, it makes the soil pack and squeeze. It can likewise also caused by small soil & shallow grounds being removed with the groundwater through well.

    This effect can be diminished by a better plan and the utilization of good filtration and groundwater treatment that keep the particles from being separated.

    ·        Impacts on Water Features

    Things that depend on the water like rivers, lakes, and springs have a cozy relationship with groundwater and are, in this way, influenced by dewatering and groundwater control by prohibition. It is essential to keep in mind that groundwater and water-dependent things have eco-systems and fill in as territories. An unfriendly impact of these water bodies will have a huge -ve effect on the earth.

    ·        Water Resource Depletion

    When groundwater is removed for longer periods and in huge amounts for personal or commercial use, it can conceivably bring down groundwater levels and reduce yields. This exhaustion brings about a decrease in significant water assets for other people. An answer to this issue can be an artificial recharge method that infuses release from siphon water back in the ground.

    Conclusion

    It is crucial to perceive and decrease the effects of dewatering and groundwater control on the earth as dependable residents of the world. We should embrace great construction dewatering treatment system design, examination strategies, and better groundwater remediation innovation to alleviate these issues before it is past the point of no return.

    Porotherm bricks are perforated clay brick. It is perforated horizontally or vertically.

    Size: 400 x 200 x 200mm

    It is a natural brick which has thermal insulation made from coal ash, natural clay and rice husk.

    Following are some advantages of porotherm bricks:

    1. Very good strength: compressive strength of brick is greater than 3.5 mm. The presence of terracotta gives higher strength to the bricks.
    2. Thermal insulation; due to its perforation it has high thermal insulation characteristics.
    3. Durability: perforated bricks have a water absorption ratio is around 15% which reduces the probability of cracks, dampness and shrinkage of walls. Also due to the high compressive strength and characteristics of fire resistance also make it highly durable and long-lasting.
    4. Economical: due to the method of perforation it reduces the manufacturing cost which saves energy and operating cost. This type of bricks balance the inner temperature with an outer temperature and avoid the usage of AC or heater in summer and winter respectively.
    5. Friendly to the environment: this brick can be recycled. all the materials for manufacturing of these bricks are natural which does not cause any allergic effect to the environment.
    6. Increases construction speed: for the construction of the wall made with porotherm bricks does not need curing. Due to its lightweight handling is easy and quick which reduces effective labour time.
    7. Porotherm bricks should be cut with a chisel and can be fixed at a fissure cracks. This breaks n sure a dry and clean site with fast construction.

    1. Rubberized asphalt
    2. PVC membrane of waterproofing
    3. Polyurethane
    4. Cementitious coating
    5. Bituminous coating or membrane

    Waterproofing of tunnel is the challenging task of the tunnelling industry. Following are the methods of waterproofing used in the tunnelling,

    1. Waterproofing by applied spray
    2. Waterproofing by conventional sheets (sheets jointed by welding)
    3. Use of hybrid materials like waterproof concrete, admixtures mixed Portland cement and aggregate. In this case, admixtures make the concrete water-resistant.
    4. Use of PVC, rubber materials, Vimal PVC materials is globally accepted.

    Waterproofing in the tunnel is aim to give basic support and it makes the inner structure of waterproof for the age of fast and reliable transportation without any type of hazardous situations.

    Pre-stressed concrete is a form of concrete used in construction. It is substantially prestressed during production, in a manner that strengthens it against tensile forces which will exist when in service. According to the construction methods there are two kinds of prestressed concrete :-
    – Pre-tensioned concrete
    – Bonded Post-tensioned concrete
    – Unbonded Post-tensioned concrete

    The three types of members in prestressed concrete are as follows:-

    1. Neither allowing tension nor crack.
    2. Allowing tension within permissible stress but cracking is not allowed.
    3. Tension and crack both are allowed but within permissible stress.
