Unit measurement at site by measurement tape

MEASUREMENT TAPE USE AT SITE BY ANY SITE WORKER , SITE SUPERVISOR AND SITE ENGINEER

For video click on it 👈

INTRODUCTION

Every site site worker , supervisor and engineer should know how to read measurement tape become it must to know for every one without this not possible to proceed work because work proceed with measurement for accuracy and ferfect quality work

Msut know basics before going for site work

1.) 1 inch = 8 soot

2.) 1 inch = 2.54 cm

3.) 1 feet = 12 inch

4.) 1 feet = 30.48 cm

5.) 1 Yard = 3 feet

6.) 1 yard = 36 inch

7.) 1 yard = 91.44 cm

8.) 1cm = 10 mm

9.) 1 M = 100cm

10.) 1 M = 1000 mm

Trick for remainder

My focus to know in easy way

So, we have to categories in part of measurement tap by drawing line in middle

Like see in image

If we want to learn measurement tape how to read without confusion 1st of all we dividen into top and bottom

Top side measurement focus for

= soot, inch ,feet , yard

Bottom side measurement focus for

= mm , cm , metre

Remaining all unit covert on basic of conversion unit

Pilling foundation work

Pile foundations

Pile foundations are principally used to transfer the loads from superstructures, through weak, compressible strata or water onto stronger, more compact, less compressible and stiffer soil or rock at depth, increasing the effective size of a foundation and resisting horizontal loads

Pile foundations layout plan

👉For detail explanation of layout plan in video click on it

Following are the situations when using a pile foundation system can be

When the groundwater table is high.
Heavy and non-uniform loads from superstructure are imposed.
Other types of foundations are costlier or not feasible.
When the soil at shallow depth is compressible.
When there is the possibility of scouring, due to its location near the river bed or seashore, etc.
When there is a canal or deep drainage systems near the structure.
When soil excavation is not possible up to the desired depth due to poor soil condition.
When it becomes impossible to keep the foundation trenches dry by pumping or by any other measure due to heavy inflow of seepage.

Concrete mix design & mix ratio of concrete

Mix ratio of concrete

Theory:-

👉The process of selecting suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and workability as economically as possible is termed the concrete mix design.

Mix Ratio = X:Y:Z

X= cement

Y= Sand

Z = aggregate

for example taking M15

M = Mix

15 = 15 N/mm2 or MPa in 28 days curing

( compressive strength of concrete in 28 curing days after casting )

There are two types of mix

1.) Nominal Mix

2.) Design mix

1.)Nominal Mix Proportions

In the past the specifications for concrete prescribed the proportions of cement, fine and coarse aggregates.

These mixes of fixed cement-aggregate ratio which ensures adequate strength are termed nominal mixes.

M25 =1:1:2

M20 = 1:1.5:3

M15 = 1:2:4

M10 = 1:3:6

M7.5 = 1:4:8

M5 = 1:5:10

Addition of water 💧in mix

It's varies from 45% to 60% of cement quantity mixing with sand and aggregate for concrete

Like this we can say

M20 ------- 45%

.M5 ---------- 60%
