TEST ON CEMENT

Image
FOR WHAT TESTING OF CEMENT IS NEEDED Quality tests on cements at construction site (also called field tests on cement) are carried to know the quality of cement supplied at site. It gives some idea about cement quality based on colour, touch and feel and other tests. TYPES OF TESTS CONDUCTED  Tests on Cement at Construction site The following are the quality tests on cement at construction site: Color test Presence of lumps Adulteration test Temperature test Float tests Strength test Setting test Date of packing Brief explanation of above tests are discussed below: Color Test of Cement The color of the cement should be uniform. It should be grey colour with a light greenish shade. Presence of Lumps The cement should be free from any hard lumps. Such lumps are formed by the absorption of moisture from the atmosphere. Any bag of cement containing such lumps should be rejected. Cement Adulteration Test The cement sh...

COVER TO REINFORCEMENT

Image
COVER TO REINFORCEMENT Concrete  cover, in reinforced  concrete, is the least distance between the surface of embedded  reinforcement  and the outer surface of the concrete (ACI 130). The concrete  cover  depth can be measured with a  cover  meter.                                                                                                                                                                                       PURPOSE OF REINFORCEMENT Minimu...

POISSON'S RATIO

Image
POISSON'S RATIO THE PICTURES WILL MAKE YOU UNDERSTAND THE CONCEPT EASILY where,          1.ELASTIC MODULUS : Young's  modulus  ( E ) describes tensile  elasticity , or the tendency of an object to deform along an axis when opposing forces are applied along that axis; it is defined as the ratio of tensile stress to tensile strain. It is often referred to simply as the  elastic modulus .          2.POISSON'S RATIO : T he ratio of the proportional decrease in a lateral measurement to the proportional increase in length in a sample of material that is elastically stretched. LET US WATCH THE  VIDEO WITH A CLEAR EXPLANATION

OVERALL CONVERSION BETWEEN METRIC AND CUSTOMARY UNITS

AS A CONTINUATION OF UNITS OF MEASUREMENT THE FOLLOWING VIDEOS  WILL COVER THE TWO DIMENSIONAL AND THREE DIMENSIONAL UNITS:  THAT IS LENGTH,AREA,VOLUME: 1. BASIC DIFFERENCE:  2.SIMPLE CONVERSIONS WITH EXAMPLES: 3.DIFFE RENCE BETWEEN METRIC AND IMPERIAL SYSTEM IN SIMPLE ENGLISH: 4.CONVERSION OF CAPACITY BETWEEN METRIC AND IMPERIAL UNITS: 5.CONVERSION OF UNITS WITHIN METRIC SYSTEM: THUS , THE UNITS OF MEASUREMENT  TOPIC IS MORE OVER COVERED WITH  EASIER WAY OF UNDERSTANDING THE CONVERSIONS. WE WILL SEE A NEW TOPIC FROM NEXT POST  ONWARDS..............

Converting Customary and Metric Units

COMPARISON OF CUSTOMARY AND METRIC UNITS: BELOW ARE SOME VIDEOS WILL GIVE YOU A CLEAR IDEA ON CONVERSION TO MAKE IT SIMPLE: WILL BE CONTINUED.............                                                                                        

CUSTOMARY UNITS

In the last post we have discussed THE LINEAR MEASUREMENTS IN METRIC SYSTEM. Like wise we will see the  LINEAR MEASUREMENTS IN CUSTOMARY SYSTEM .  LET US SEE THE UNITS:  THE FREQUENTLY USED LINEAR UNITS ARE:                 Inches           Feet             Yard             Mile LENGTH: THE BELOW PICTURE WILL REPRESENT THE  ONE DIMENSIONAL UNIT CONVERSIONS : Below are some pictures representing the units in a easy remembering way: THE LINEAR UNITS  WILL BE CONTINUED WITH COMPARISON OF METRIC AND CUSTOMARY SYSTEM (LINEAR UNITS) ...............
