Living Concrete




Living Concrete is the technology where bacteria can be used to make concrete in a greener and sustainable way. In the earlier years when this concrete is made at that time bacteria is used in the concrete to heal its cracks its own but now a days these can do much more than that.

Cement is the second most consumed material by humans after water. And it emits 6% carbon dioxide to the atmosphere during its production and when it mixes with concrete, the emissions increase. The bacteria which is used in the living concrete is called Synechococcus. This bacterium comes under the criteria of Cyanobacteria. During the process of photosynthesis it gains its energy. In this process, it absorbs carbon dioxide, sunlight, and some other nutrients in the presence of chlorophyll and releases calcium carbonate and oxygen.

They are also called as Green Algae because of its green colour due to the chlorophyll. They can be reproduce by the process Binary Fission. These cyanobacteria have a tolerance to extreme conditions and the ability to exist without vitamins.

When these bacteria mixed with gelatin, sand, and some nutrients in a liquid mixture, bacteria staretd its gelatin, sand, and some nutrients in a liquid mixture. When this liquid cooled down it converts into a gel form and become a hard material and with stand with loads.

Advantages of Living Concrete

Ø  In this concrete despite of carbon dioxide, oxygen is released to the atmosphere and these bacteria absorbs carbon dioxide.

Ø  It can be used where very few resources are available.

Ø  More concrete can be produced from the existing concrete as living concrete continues to grow and we need to add some sand and nutrients to make more concrete.

Drawbacks of Living Concrete

Ø  To gain more strength, Concrete has to be dried thoroughly. Due to this, the viability of bacteria will have to be compromised.

Ø  For this concrete, humid weather is favourable therefore it cannot be used everywhere.

Ø  This living materials properties match much more with mortar instead concrete but mortar is not as strong as concrete.

#VastuFor Home – Colours for Home

Image
Colours are playing an important part in the house. If we coloured each wall with same colour, it will end up looking bad therefore it is important to have a balance of colour in the entire house. Depending upon in which direction room is located best suitable colours have to decide. Each and every room in the house is different because every room has specific purpose. If we are using wrong colours at wrong places it will mess up. For master bedroom, it is advisable to use brown, blue and pink colours. Red is not advisable to use. Red colour will bring fights within the family, with neighbours. Whereas the blue and pink are masculine and feminine colours respectively and the brown colour gives stability. Use light green and light yellow colour for kid’s room that will help them to concentrate more on studies without wasting time. Avoid using dark blue colour in kid’s bedroom. For living room, use more of white colour.  You can use tinges of some other colours

Steam Curing of Concrete

Image
Steam curing of concrete is the method of curing the concrete elements in water vapour. This curing is performed either under atmospheric pressure or high-pressure steam. This method is used where there is a need for accelerated strength gain and the concrete requires additional heat to perform hydration. This is done in low temperature zone. This technique is used for gaining high early strength and this requires for the manufacture of precast and prestressed concrete units. Steam Curing can be performed by two methods: Ø   Steam Curing of Concrete at Atmospheric Pressure: The steam curing process is performed within a temperature range of 70 to 90F per hour which is merely dependent on the size and the shape of the concrete element. In this steam curing is done in an enclosed chamber in order to avoid any sort of heat loss and moisture. The properly hardened concrete is applied to the steam enclosure after a delay period of 3 hours. It is not exposed directly to

Control Joints in Concrete Slab

Image
Control joints are provided in a concrete slab to reduce cracks formed due to shrinkage. The specifications of the control joints such as the depth, timing and place of the cut play an important role in the efficiency of the control joint. The time when the concrete slab is saw-cut to make control joints is an important aspect for the efficient use of control joint. When the concrete is sawed with the help of blade before it has reached its initial setting time, the aggregates may strew out of the concrete slab and leave a messy, weakened edge along the joint. This effect is known as Ravelling. Sawing too late can result in uncontrolled cracking as the concrete contracts during curing. It is recommended to place the control joints in the centre of the slab dividing the concrete into equal segments. The spacing of the joints is in the range of 24 to 36 times the thickness of the concrete slab. The factors that determine the location of control joints are: Continui
