Different types of sand zones are used in construction work depending on their properties.

• Coarse sand is used for concrete and masonry work.

• Fine sand is used for plastering and finishing work.

• Pit sand is used for filling and leveling.

• River sand is used for construction of dams and bridges.

• Sea sand should not be used in construction due to its high salt content.

M.D.D. and O.M.C. are important parameters for W.M.M. and G.S.B.

• M.D.D. stands for Maximum Dry Density, which is the maximum density that can be achieved for a given soil at a specific moisture content.

• O.M.C. stands for Optimum Moisture Content, which is the moisture content at which the maximum dry density can be achieved.

• W.M.M. stands for Wet Mix Macadam, which is a type of road construction material made by mixing aggregates, water, and a binding agent.

• G.S.B. stands for Gra...read more

Flexural load test is a test to determine the strength of a material under bending loads.

• It involves applying a load to a beam or other structural element until it fails.

• The test is commonly used in construction and engineering to determine the strength of materials such as concrete, steel, and wood.

• The results of the test can be used to design structures that can withstand the expected loads and stresses.

• The test can also be used to evaluate the quality of materials and to i...read more

C.B.R. value depends on various factors.

• Type of soil

• Moisture content

• Compaction effort

• Penetration depth

• Testing method

Bulk density of coarse aggregate is 1600kg/m3.

• Bulk density is the mass of a unit volume of material.

• It is typically measured in kg/m3 or lb/ft3.

• Coarse aggregate is typically used in concrete mixtures.

• The bulk density of coarse aggregate can affect the strength and durability of concrete.
