What is the Average Density of Soil?
INDER KUMAR YADAV
Soil density is defined in two different terms. particle density bulk density In terms of particle density the density of soil is 2.65 gram per cubic centimeter. in terms of bulk density, the density of soil is 1.6 gram per cubic centimeter. Image shows below that how the density of soil is measureRead more

there are different types of plaster. Some are given below:
Sand faced plaster is actually a mixture of cement sand mortar which is applied over brickwork and also works as a damp-proof coat over masonry.
This type of plaster is used to give a finishing touch to a surface let’s say to walls and ceilings. To some extent, it also serves as a sound and thermal insulation material.
It adds a decorative touch to buildings and also provides a sustainable base for the paint colors.
how to apply it
The first coat of the sand-surfaced cement plaster is applied in 1:4 cement mortar ratios with coarse sand. The plastering is left for seven days and then a second coat is applied in a 1:3 cement plaster ratio on the first coat. In the second coating, a sponge is applied on its wet surface and it should be well-watered for at least 15 days.

INDER KUMAR YADAV
Impurities such as manganese, chromium, nickel, tungsten, molybdenum, and vanadium to produce alloys that produce properties which have specific properties. Also, steel has some amount of carbon, which is to be removed so that if they contain a high amount of carbon, then it will make steel brittleRead more

INDER KUMAR YADAV
For visual checks on the reinforcement bar at site you can do following step. check for manufacture seal which is present at every meter of steel. the bars should not be rusty.. check for weight of steel in bundle. check if the rods are of equal length. check for overall quality of steel.

INDER KUMAR YADAV
Zero air void line is the line that shows the relationship between the water content and the dry unit weight of the soil with a 100% degree of saturation or at zero void is called the zero air void line or 100% degree of saturation line. But this does not mean that 15% air void is equal to an 85% deRead more

See lessWhat is the difference between fe 500 and fe 500D rebars?
INDER KUMAR YADAV
Here fe 500:- " fe "means that it is made from TMT bars, and the 500 denotes the yield strength of the bars. whereas fe 500D:- here "fe" and "500" means the same, but here "D" means for ductility means that these bars are made for more elongation than the normal "fe500" bars. Fe 500D has minimum perRead more
Here fe 500:- ” fe “means that it is made from TMT bars, and the 500 denotes the yield strength of the bars.
whereas
fe 500D:- here “fe” and “500” means the same, but here “D” means for ductility means that these bars are made for more elongation than the normal “fe500” bars.
Fe 500D has minimum percentage elongation i.e 16% whereas Fe 500 has a value of 12% elongation and also the chemical composition point, Fe 500D has 0.25% Carbon (max) as compared to 0.30% (max) in Fe 500. Also, the maximum percentage of Sulphur and Phosphorous are lower in Fe 500D.
Fe 500D with lower quantities of carbon, sulfur and phosphorous, helps in preserving the steel and resisting earthquake shocks in future.
See lessWhy are 6 cubes cast for testing the Compressive Strength?
INDER KUMAR YADAV
6 cubes are casted for checking the compressive strength of concrete as it is given in the code and as, In Indian standard, there are two different IS code which is defining concrete sampling frequency, those are IS 456 and IS 4926. As per is 456 Clause 15.2.2, Sampling frequency is 0–5m³ - 1 set 6–Read more
6 cubes are casted for checking the compressive strength of concrete as it is given in the code and as,
In Indian standard, there are two different IS code which is defining concrete sampling frequency, those are IS 456 and IS 4926.
As per is 456 Clause 15.2.2, Sampling frequency is
0–5m³ – 1 set
6–15m³- 2 set
16–30m³ 3 set
30–50 m³ 4 set and +1 set for every 50m³ concrete.
This cubes are to be tested in 28 days.
Additional samples should be casted if required for 1 day, 3 days, 7 days testing done.
As per IS 4926 Clause 6.3.2,
One set of samples to be casted in every 50m³ concrete and additional samples (1 day, 3 days,7 days etc) to be casted if required.
Here, 1 set sample means 3 nos of cubes.
Whatever, the sampling frequency and number of samples to be cast to be fixed mutually by both vendor and client
See lessWhat is the benefit of smaller dia steel instead of larger dia steel in slab and beam?
INDER KUMAR YADAV
There are many benefits of using a large number of small dia bars than a small number of large dia bars. The reasons are as follows. to provide ductility to the structure, i.e. (beam and slab ) which is not available in the concrete. to provide stability to the structure as the bars have rib designRead more
There are many benefits of using a large number of small dia bars than a small number of large dia bars. The reasons are as follows.
and because of these reasons, it is not possible to provide all these factors using a single bar, and therefore we have to provide a small number of large diameter bars.
