What is full form of SP in Indian standard code?
Vivek Patel
SP mean "special publication" That book called handbook This SP handbook are published by BIS (bureau of Indian standard) Some rule are given which we can use directly from that SP handbook

See lessWhat is the CBR value for sub grade in road construction?
Vivek Patel
CBR value for subgrage indicate subgrade material quality CBR value is taken at 2.5mm & 5 mm penitration. For road construction we use irc37 code in subgrade material CBR value should be nearly 15-19% .

Explain the Seasoning of Stone?
Vivek Patel
Newly cut stone has some moisture which called quarry sap. Due to moisture, stone durability decrease. So we need to Remove that moisture content and that process of removing moisture (quarry sap) from stone is called seasoning of stone. Basically 5-6 month need to the done seasoning process

Vivek Patel
The concealed beam is a hidden beam in the slab. it is used at the opening of slab-like stair opening see figure This red line show concealed beam it is used for save headway of floor, to give flatter surface, to resist redistribution of load, to divide and distribution as per design basically thisRead more
The concealed beam is a hidden beam in the slab. it is used at the opening of slab-like stair opening see figure
This red line show concealed beam
it is used for save headway of floor, to give flatter surface, to resist redistribution of load, to divide and distribution as per designÂ
basically this type of beam we provide at
- stair opening
- OTS opening
- sink slab strengthning
- to convert one way and two way load distribution system
See lessIf we reduce water content below the shrinkage limit of soil, What will happen in the pore of soil?
Vivek Patel
shrinkage limit is the maximum water content at which if we reduce water content further than soil volume doesn't change, we can also say that at shrinkage limit, water is in just saturated stage. let's see the graph of water content and volume change with shrinkage limit ws= shrinkage limit wp= plaRead more
shrinkage limit is the maximum water content at which if we reduce water content further than soil volume doesn’t change,
we can also say that at shrinkage limit, water is in just saturated stage.
let’s see the graph of water content and volume change with shrinkage limit
ws= shrinkage limit
wp= plastic limit
wl=liquid limit
at below shrinkage water content water is spill out/remove from voids of soil and that voids fill with the air. Hence voids doesn’t change, so volume doesn’t change. and soil become 3 phase structure air, water and solid particles.
See lessWhat is Relative Compaction?
Vivek Patel
Relative compaction is a ration of the density of soil at site to the maximum dry density of soil. like we have maximum dry density of soil have 1800 kg/m3 which determine in lab now on site we can archive 1700 kg/m3 by compaction of dumped soil so relative density of that soil on site is =1700/1800Read more
Relative compaction is a ration of the density of soil at site to the maximum dry density of soil.
like we have maximum dry density of soil have 1800 kg/m3 which determine in lab
now on site we can archive 1700 kg/m3 by compaction of dumped soil
so relative density of that soil on site is =1700/1800=0.9444 = 94.44%
it is use for
- to know how much density we archive compare to design in lab
- sometime in specification minimum criteria of relative density are given, ex- minimum relative density at whole site should be 90%.
- from relative density we can calculate actual movement of soil, which is very important in tall building and structural durability calculation

See lessWhich type of soil is present in desert?
Vivek Patel
Basically aeolian soil is present at desert it is formed by wind flow and it made from fine dust or very fine particle of rocks or any soil sometimes there is also present loess type of soil which is very fine compared to aeolian soil loess soil is a form by wind blowing on the desert and its transpRead more
Basically aeolian soil is present at desert it is formed by wind flow and it made from fine dust or very fine particle of rocks or any soil
sometimes there is also present loess type of soil which is very fine compared to aeolian soil
loess soil is a form by wind blowing on the desert and its transport very easily by wind. In other work in the desert, there is very fine sand and a silt present which has no cohesion and highly calcareous also that type of soil has very little mineral content.
