Concrete mix design web
Calculator for Nominal Design of Concrete Mix for different proportions of cement and aggregates.(SI units)
Concrete Mix Design
This calculator is useful for nominal design of concrete mix of different proportions M25 (1:1:2), M20 (1:1.5:3), M15 (1:2:4), M10 (1:3:6), M7.5 (1:4:8). You can get the dry amount of ingredients (cement, fine aggregate and coarse aggregate) of concrete as well as the amount of water needed to produce concrete of desired workability. For example M15 corresponds to a Mix for Concrete with characteristic compressive strength of 15 MPa (15 N/mm2) and the mix proportion 1:2:4 concrete means 1 part of cement mixed with 2 parts of fine aggregate (sand) and 4 parts of coarse aggregat (stone pieces). Water is essential for producing concrete. The water to cement ratio is generally selected in the range of 0.4 to 0.6 depending on required workability. Desnsity of cement is taken as 1440 kg/m3. It is assumed that dry volume of concrete = 1.54 times the wet volume of concrete. This calculator gives the dry volume of agggregates. If you want to determine the weight of aggregates just multiply the dry volume by the bulk density of aggregate. This calculator is based on the guidelines of IS codes.
Please enter the volume of wet concrete to be produced and select the desired concrete grade with appropriate water to cement ratio in the form given below and start calculations.

The engine
The engine is the heart of your car. It is a complex machine built to convert heat from burning gas into the force that turns the road wheels.
The chain of reactions which achieve that objective is set in motion by a spark , which ignites a mixture of petrol vapour and compressed air inside a momentarily sealed cylinder and causes it to burn rapidly. That is why the machine is called an internal combustion engine . As the mixture burns it expands, providing power to drive the car.
To withstand its heavy workload, the engine must be a robust structure. It consists of two basic parts: the lower, heavier section is the cylinder block, a casing for the engine's main moving parts; the detachable upper cover is the cylinder head .
The cylinder head contains valve-controlled passages through which the air and fuel mixture enters the cylinders, and others through which the gases produced by their combustion are expelled.
The block houses the crankshaft , which converts the reciprocating motion of the pistons into rotary motion at the crankshaft. Often the block also houses the camshaft , which operates mechanisms that open and close the valves in the cylinder head. Sometimes the camshaft is in the head or mounted above it.
Different engine layouts
In-line engine
The simplest and most common type of engine comprises four vertical cylinders close together in a row. This is known as an in-line engine . Cars with capacities exceeding 2,000cc often have six cylinders in line.
V-8 engine
The more compact V-engine is fitted in some cars, especially vehicles with eight or 12 cylinders, and also some with six cylinders. Here the cylinders are arranged opposite each other at an angle of up to 90 degrees.
Horizontally-opposed engine
Some engines have horizontally opposed cylinders . They are an extension of the V-engine, the angle having been widened to 180 degrees. The advantages lie in saving height and also in certain aspects of balance.
The cylinders in which the pistons operate are cast into the
block, as are mountings for ancillary equipment such as a filter for the oil
which lubricates the engine, and a pump for the fuel. An oil reservoir , called
the sump , is bolted underneath the crankcase .

We people all over the world are very much into the usage of smart watches in our daily life because of its aesthetic look and its functions. But we might have not analyzed about its features behind its working. Stay ahead of the technology curve and get to know all about smart watches! This comprehensive guide will let you know what features and specs you should look for in a smart watch.
WHAT IS SMART WATCH ?
Smart watch is a watch with digital display that can be connected with your mobile phones to manage calls and messages you get in your mobiles. It can also detect your various activities including the following
1. Health activity
a. Heart rate
b. Sleep
c. Blood oxygen
d. Breathe
2. Sports/Exercise activity
a. Running
b. Walking
c. Cycling
d. Hiking
e. Climbing
f. Treadmill
g. Spinning
h. Yoga
i. Fitness
3. Weather
4. Direction and speed
HOW THIS WORKS?
Bluetooth connectivity is the wireless technical tool in linking your mobile calls and messages to your smart watch. Bluetooth is a connecting link between two electronic devices located within a distance of about 10m to 100m apart working based on Personal Area Network. By means of Bluetooth, the watch is connected with a mobile application (eg: dafit app, noisefit app, BT notifier, Fit pro etc.) that enables the watch to access various others applications on your mobiles like managing your calls, messages, gmaps etc. and sensors are the technical tool in tracking your basic health parameters in this tiny device. There are various sensors to detect your health parameters. The following are few sensors.
1. GYROSCOPE
This is a type of sensor that detects your movement based on your angular velocity (i.e) Your angular movement with respect to time from a particular central point. This gyroscope function by combining itself with other sensors present inside your smart watch to detect whether you are running, walking or just shaking your wrist.
2. ELECTRO DERMAL ACTIVITY SENSOR
The conductivity produced in the skin due to increased activity of sweat glands is detected by this electrodermal activity sensors. Sweat secreted by eccrine glands due to exogeneous stimuli like weather and endogenous stimuli like memory, fear, anxiety etc detects your heartrate along with stress.
3. ULTRAVIOLET SENSOR
This detects the amount of UV rays to which the device is exposed and tells you the amount of UV and other harmful rays the person wearing this watch is exposed to.
4. GESTURE SENSOR
Gesture sensor helps in detecting the movement of your wrist and instructs the watch to perform based on the movements you have produced. For example: When you rotate your wrist the stop watch gets turned on and when you shake your wrist it automatically disconnects the call.
5. SKIN TEMPERATURE SENSOR
Non contact temperature detection by means of Infrared temperature sensors. This helps in detecting your body temperature and helps you know whether you are about to fall sick.
6. ECG SENSOR
ECG sensor detects your heart beat based on the electric impulse your heart sends when it pumps each time and the sensor by means of this electric impulse analyses your heart beat rate.
7. ACCELEROMETER
Accelerometer helps in detecting the pace steps you have walked and shows the total number of steps while you walk the entire day. It can even monitor your sleep. Smart watch is provided with a three axis accelerometer which can detect forward movement, backward movement and also it can sense earth's gravity so that it can analyse your position and rate of acceleration.
8. OXIMETRY SENSOR
Pulse oximetry sensor with the help of red and infrared LEDs measures deoxygenated and oxygenated hemoglobin. It is used to know one's oxygen saturation level (SpO2) and pulse rate. Infrared lights are more absorbed by oxygenated blood and hence it allows more red light to pass through whereas more red light is absorbed by deoxygenated blood and hence allows more infrared rays to pass through. Thereby detecting the level of oxygen in blood.
9. BAROMETRIC PRESSURE SENSOR
Aneroid cell present inside the barometric pressure sensor, expands and contracts based on the atmospheric pressure in the surrounding environment. Hence detecting your climbing, altitude in which you are present and also the atmospheric pressure.
10. PROXIMITY SENSOR
This helps the smart watch to know that you are nearby and wants to use it hence it lights up the display when you turn your wrist against your face which is an amazing battery saving technology.
11.MAGNETOMETER
Magnetometer is nothing but a technical term to describe magnetic compass sensor which helps in detecting the direction. This sensor helps in successful running of map applications.

Automatic rendering machine or automatic plastering machine is used to plaster the surface of the wall without the help of much man power. It is also called as programed plastering machine.
HOW THIS WORKS
The clamp of this rendering machine is fixed at both ceiling and flooring of the building and is placed very close to the wall surface where rendering is to be carried out. It can move only one time in vertical direction to plaster a surface. The machine is provided with rails to enable the machine to move vertically. Then by means of labors the mortar is put into the bucket/tray of this machine and thickness of plastering is adjusted as per the requirements and the plastering is carried out on the required surface.
ADVANTAGES
1) Less manpower is required.
2) More area could be covered in a single day.
3) Very smooth plastered surface is obtained.
DISADVANTAGES
1) Fixing the clamp and shifting the machine to next area is a cons.
2) This machine couldn't be used in very narrow areas.
3) These machines works well on internal wall but you have to do cornice and corner plastering manually.
