Enhancing Home Design using IoT Tech

In India, the number of IoT devices will increase to 2.7 billion units by 2020 according to a NASSCOM report. If you compare that with the 200 million units that the report states were available in 2016, you can see just how significant that increase will be. With this kind of forecast, it is not surprising that home designers and construction companies are looking into ways they can exploit these changes to increase the value of homes in India. IoT can be used to enhance security, entertainment and change the way you light your home.

IoT and Security

There are security cameras, door and window sensors and other gadgets that work using the internet of things. These devices can either be connected to the internet through Wi-Fi, or may use protocols like Zigbee to communicate with other devices in your home. For example, your connected security camera can send you a notification when someone is standing by your door when you are away from home. While this actually enhances your home security, it may make you vulnerable to hackers that could use the internet to access your home’s security cameras. To prevent this you may need to use technology that secures the networks your smart devices use to communicate with one another. One way to do this is by securing your PC, tablets and smartphones online using VPN. You may also turn to devices that use protocols such as Radio Frequency (RF), which are harder to hack.

IoT for maintaining your house structure

Any house buyer will appreciate technology that helps maintain the structure of their home to enhance its durability.  One way this can be done is by installing sensors in strategic areas of your plumbing system to help you detect water leaks before they become a major problem. These sensors can send notifications to your phone when there is a leak. Waterproofing your home prevents paint peels, warping of wood on wooden floors, cracks and other major issues. There are other IoT devices that can detect gas leaks, smoke and other air impurities in your home.

IoT and your Electricity Bill

Home designers that want to incorporate IoT devices in homes should care more about the benefits these devices bring to a home not their appearance. They should also be aware that a few quality smart devices in a home are better than a home cluttered with smart devices that may never be used.

Turning off all the lights and devices that use electricity when they are not being used is one way to cut your electricity bill. However, IoT based technologies can automatically regulate power supply associated with electronics or appliances in your home during peak usage periods. This can save many Kerala residents a lot of money especially during the summer months. If you cannot afford a full IoT electricity management system, you can still save energy and money by using devices such as smart thermostats, smart lights and smart plugs. For example, smart plugs can automatically turn off devices that may be wasting energy in your home, and smart lights can turn off if they detect that a room is not occupied.

M Sand

M Sand | Substitute for River Sand

by with No Comment Civil InformationsengineeringMaterialsProducts

M sand (manufactured sand) is a substitute of river sand for concrete construction . Manufactured sand is produced from hard granite stone by crushing.The crushed sand is of cubical shape with grounded edges, washed and graded to as a construction material. The size of manufactured sand (M-Sand) is less than 4.75mm.

Why Manufactured Sand is Used?

M Sand  is an alternative for river sand. Due to fast growing construction industry, the demand for sand has increased tremendously, causing deficiency of suitable river sand in most part of the word.

Due to the depletion of good quality river sand for the use of construction, the use of manufactured sand has been increased. Another reason for use of M-Sand is its availability and transportation cost.

Since M sand can be crushed from hard granite rocks, it can be readily available at the nearby place, reducing the cost of transportation from far-off river sand bed.

Thus, the cost of construction can be controlled by the use of M sand as an alternative material for construction. The other advantage of using M-Sand is, it can be dust free, the sizes of m-sand can be controlled easily so that it meets the required grading for the given construction.

Advantages of Manufactured Sand (M Sand)

  • It is well graded in the required proportion.
  • It does not contain organic and soluble compound that affects the setting time and properties of cement, thus the required strength of concrete can be maintained.
  • It does not have the presence of impurities such as clay, dust and silt coatings, increase water requirement as in the case of river sand which impair bond between cement paste and aggregate. Thus, increased quality and durability of concrete.
  • M-Sand is obtained from specific hard rock (granite) using the state-of-the-art International technology, thus the required property of sand is obtained.
  • M-Sand is cubical in shape and is manufactured using technology like High Carbon steel hit rock and then ROCK ON ROCK process which is synonymous to that of natural process undergoing in river sand information.
  • Modern and imported machines are used to produce M-Sand to ensure required grading zone for the sand.

Properties of Manufactured Sand for Concrete Construction

 

Higher Strength of concrete

The manufactured sand has required gradation of fines, physical properties such as shape, smooth surface textures and consistency which makes it the best sand suitable for construction. These physical properties of sand provides greater strength to the concrete by reducing segregation, bleeding, honeycombing, voids and capillary.

Thus required grade of sand for the given purpose helps the concrete fill voids between coarse aggregates and makes concrete more compact and dense, thus increasing the strength of concrete.

Durability of concrete

Since manufactured sand (M-Sand) is processed from selected quality of granite, it has the balanced physical and chemical properties for construction of concrete structures.

This property of M-Sand helps the concrete structures withstand extreme environmental conditions and prevents the corrosion of reinforcement steel by reducing permeability, moisture ingress, freeze-thaw effect increasing the durability of concrete structures.

Workability of concrete

Size, shape, texture play an important role in workability of concrete. With more surface area of sand, the demand for cement and water increases to bond the sand with coarse aggregates.

The control over these physical properties of manufacturing sand make the concrete require less amount of water and provide higher workable concrete. The less use of water also helps in increasing the strength of concrete, less effort for mixing and placement of concrete, and thus increases productivity of construction activities at site.

Less Construction Defects

Construction defects during placement and post-concreting such as segregation, bleeding, honeycombing, voids and capillarity in concrete gets reduced by the use of M-Sand as it has optimum initial and final setting time as well as excellent fineness.

Economy

As discussed above, since usage of M-Sand has increased durability, higher strength, reduction in segregation, permeability, increased workability, decreased post-concrete defects, it proves to be economical as a construction material replacing river sand.

It can also save transportation cost of river sand in many cases.

Eco-Friendly

Usage of manufactured sand prevents dredging of river beds to get river sand which may lead to environmental disaster like ground water depletion, water scarcity, threat to the safety of bridges, dams etc. to make M-Sands more eco-friendly than river sand.
