GRADE OF CONCRETE , concrete grade table , concrete grade for slab, concrete grades and mix ratio pdf , types of concrete ,concrete grade 20 ,
GRADE OF CONCRETE AS PER IS CODE
The clause states ''the concrete is normally a gain of strength beyound 28 days the quantum of increase depend upon the grade and type of cemnt ,curing etc .the design should be based on 28 days characterstic strength of concrete unless there is an evidence to justify a higher strength for a particular structure due to age .
in simple language ,the strength of the concrete ,the minimum strength the concrete should have 28 days of initial construction .
M stands for Mix
15,20 stands for number compressive strength of concrete in N/mm2
Group
grade of concrete are divide in three parts Ordinary concrete,Standard concrete , High strength concrete.
Many research workers have attempted to estimate the strength of concrete at 1 , 3 or 7 days and correlate it to 28 days strength .
Grade of concrete use for slab
⦁ Genrally M 10 and M 15 grades of concrete are used for leveling course ,footing etc
⦁ standard concrete M 20 is applicable for reinforced cement concrete works for coloumns , beams , slab etc. moreover, the high strength concrete has its application for high rise building and some bridges .

WHY SUGAR ARE ADDED IN CONCRETE
WHY SUGAR ARE ADDED IN CONCRETE
Sugar is actually a well known 'retardant of concrete and often used to help adjust the setting times especially in emergencies,some transmit mixer transporting RMC gets stuck in the mid of traffic for a long time then what will be remedy in avoiding concrete from getting set . ...in the case of sugar the setting process is slowed down
In simple terms ,it based on glucose catalytic principle. according to this formula the surface of sugar has strong polarity it results in solid adsorption thus it hinders the crystal contact and calcium silicate hydrates reaction.
Results based on test
⦁ sugar like glucose ,raffinose act as good retarders.
⦁ the addition of OPC would give retardation of 4 hrs
⦁ the amount of sugar that should be used to keep concrete from fully hardening ranges from 1.0 to 1.5 percent by weight of cement .

Difference Between Civil Site Engineer and Site Supervisor
Difference Between Civil Site Engineer and Site Supervisor
Site engineer
A site engineer is a part of the site management team,and takes some of the responsibility for security,health and safety .site engineer mark out the site make sure designs and applied correctly and lise with main and sub contractor and the site manager .
site engineer depends on the type of work involved .
⦁ Calculating the quantity of material.
⦁ Resolving technical issues.
⦁ Quality control.
⦁ Preparing record drawings technical reports, site diary .
⦁ supervision and counselling junior .
⦁ tracking up the material wastage.
⦁ measurement and valuation .
⦁ checking material and work in progress.
⦁ setting out the work .
site supervisor
The role of supervisor generally involves the management and supervision of a construction site in accordance with health and safety guidelines the site supervisor will typically work closely with the site foreman, who is responsible for organising construction work on site and report to the project manager .
site supervisor depend on the types of work involved .
⦁ supervising the labour .
⦁ Monitoring the work .
⦁ Monitor progress, oversee the delivery of materials .
⦁ Responsibility of supervising the whole site .
⦁ study the drawings and execute the work .
⦁ Ensure that work done safely .
⦁ oversee operation .

AAC Block Vs Red bricks :How to Make the Right Choice!
AAC Block Vs Red bricks :How to Make the Right Choice!
AAC Block
Autoclaved aerated concrete is light weight durable building product. AAC block is light weight and compare to the red bricks.
Raw material
It is manufactured through a reaction of aluminium powder and cement fly ash ,lime and sand etc.
ADVANTAGES
⦁ AAC block are light weight building material .
⦁ AAC block are very easy to handle and ordinary tools can be used for cutting. the AAC block are perfect in shape and size.
⦁ AAC block can be used to building both internal and external walls.
⦁ sound proof in nature .
⦁ less labour are required .the speed of work will be double than that of the brick work.
⦁ AAC block are recommended for high-rise building ,because it educed to total dead load .
⦁ require less mortar due to even surface & less number of joints.
⦁ AAC blocks masonry requires less curing , hence less water and less electricity are required .
⦁ 1 cum block work cost is (around INR 3150/ -in india )
⦁ steel saving up to 18% & concrete saving up to 9 %
⦁ The AAC Block have a compressive strength of an average 3 , 4.5 N/mm3 ( natural dry density 550-650 Kg/m3 )
⦁ AAC Block conduction of heat is high in comparison to clay and Brick.
⦁ they are also easy to transport especially when they have to be carried to the upper floors.
DISADVANTAGES
⦁ Plaster sometimes does not stick properly because of its smooth surface.
⦁ The production cost per unit for AAC block is higher .
RED BRICKS
Red brick is small block ,made of clay it is used in masonry construction material in creating different structure such as ,Building ,foundation,bridges ,flooring , external walls etc.
RAW MATERIAL
Red brick are made from a mixture of clay, sand , lime or magnesia etc.
ADVANTAGES
⦁ Very low maintenance cost is required.
⦁ Reusable and recyclable .
⦁ Compressive strength of brick is good
⦁ weight of Red brick is -----------3.5 to 4.00kg
first class brick
size - L - 9
H- 3
W-4.5 (inch)
⦁ water absorption of first class brick is 12 to 15 %
⦁ Red brick are used load bearing and non-load bearing walls.
⦁ 1 cum brick cost is lower (2700/in India )
DISADVANTAGES
⦁ Labour cost are very high.
⦁ rough surfaces of bricks may cause molds growth if it is not properly cleaned .
⦁ requires more mortar.
