What is bulking of sand?

Bulking of sand means increase in it's volume due to presence of surface moisture . The volume increases with increase in moisture content . The volume may increase up to 20 to 40% when moisture content is 5 to 10 %.Due to moisture in each particle of sand, sand gets a coating of water due to surface tension which keeps the particles apart. This causes an increment in volume of sand known as Bulking.- Edited by KASEE SREENIVAS# Hindustan Construction Company


Why is beach sand not suitable for concrete designing?

Sand from a beach is contaminated with all sorts of chemicals that will cause severe deleterious reactions to a concrete paste. If we are speaking of sand from an ocean environment the salt [Chloride] content is around 4%. Chlorides commence corrosion cell formation on embedded steel reinforcement in a matter of hours. With corrosion comes rust which expands the volume area of the steel. As the steel corrodes and expands the expansion causes a concrete to crack. When a crack becomes larger it allows even more chlorides moisture and oxygen free access to the steel which corrodes even faster. A design using beach sand is a prescription for concrete failure. Attempts at washing a beach sand are futile. Structures built with beach sand are doomed from the day they are poured


How do you calculating sand for 1M3 comcrete?

Simply calculate volume of sand as you calculated volume of cement to be used, just don't multiply it with 1440, divide by 50 as in case of calculating cement.you will get your answer in m3 of sand.


What is the specification for silt content in sand?

first of all take the sample of the sand and insert it into a measuring jar, then add water as per required,then add half spoon salt for better setting time. shake the jar slowly....and wait for 10 minutes. after 10 minutes you can see the different layer of the actual sand,silt and water. for calculating the SILT CONTENT:- silt divide by total height .that means sand+silt=total height. multiply by100 for percentage. you can calculate silt content after 3 hr. also.


Why would you need to pump sand under your house?

generally they pump sand or gravel under house for the footers and the foundation. the sand or gravel helps to make the concrete they are going to pour shift or move less than what it would if it where just on the ground/ dirt, it also creates a barrier from the moisture in dirt. usually depending on state building codes the thickness of the sand or concrete should be between 4" to 12". In cold weather they like to use sand because it does freeze as hard as soil.

What is the optimum moisture content of soil?

The water content corresponding to the maximum dry unit weight or maximum dry density is know that as optimum moisture content.(o.M.c.) or optimum water content (o.w.c) maximum dry density is achieved at higher O.M.C.for cohesive soils or fine grained soils s compared to cohesionless soils.(sand 6-10%0


How do you find moisture content in sand?

Moisture content in sand can be determined by taking a sample, drying it in an oven, and then weighing it before and after to calculate the difference in weight. The moisture content is expressed as a percentage of the weight of water compared to the dry weight of the sample.


What is the typical moisture content of dry silica sand?

0.08%


How do you find the moisture content using sand cone?

To find the moisture content using a sand cone method, you weigh the sand cone before and after filling it with soil, then calculate the weight of the soil added. After drying the soil sample, weigh it again to find its dry weight. From these weights, you can calculate the moisture content as a percentage of the water content in the soil.


Is determined by the angle of repose for dry sand?

Yes, the angle of repose for dry sand is the maximum angle at which sand can remain stable without collapsing. It is influenced by factors such as grain size, shape, and moisture content, and can vary depending on the specific characteristics of the sand material.


How do you testing of bulking of sand?

Permissible limits of bulking of sand in percent?

Which is heavier sand or clay?

Clay is heavier than sand since its density and its moisture content cause it to be heavier.


How many tons does a cubic meter of wet sand weigh?

It will depend on (a) the bulk density of the dry sand and (b) the moisture content of the wet sand.


How does soil texture affect moisture content of the soil?

Soil texture affects moisture content by influencing water retention and drainage. Fine-textured soils such as clay hold water more tightly, leading to higher moisture content, while coarse-textured soils like sand allow water to drain more freely, resulting in lower moisture content. The balance of sand, silt, and clay in the soil determines its texture and thus its ability to retain moisture.
