M20 grade is a mix of concrete that has a compressive strength of 20 megapascals (MPa).
M20 grade is commonly used in construction for residential and commercial buildings.
It is a mix of 1 part cement, 1.5 parts sand, and 3 parts aggregate.
The water-cement ratio should be around 0.5 for M20 grade concrete.
M20 grade concrete is suitable for foundations, beams, and slabs.
The curing time for M20 grade concrete is around 28
TMT stands for Thermo-Mechanically Treated bars, which are high-strength reinforcement bars used in construction.
TMT bars are made by subjecting mild steel bars to a series of processes involving heat treatment and rapid cooling.
The resulting bars have a hard outer layer and a soft inner core, making them more resistant to corrosion and fatigue.
TMT bars are commonly used in reinforced concrete structures, such as build...
The density of steel is around 7.85 g/cm³.
Steel density is the mass per unit volume of steel.
It is measured in grams per cubic centimeter (g/cm³).
The density of steel varies depending on its composition and properties.
The density of mild steel is around 7.85 g/cm³.
The density of stainless steel is around 7.9 g/cm³.
The density of high carbon steel is around 7.8 g/cm³.
Nominal mix is a rough estimate of proportions while design mix is a precise mix of ingredients.
Nominal mix is used for small construction projects while design mix is used for large projects.
Nominal mix is not as accurate as design mix.
Nominal mix uses volume batching while design mix uses weight batching.
Nominal mix is cheaper than design mix.
Example of nominal mix: 1:2:4 (cement:sand:aggregate)
Example of design mix:
BBS stands for Bar Bending Schedule, which is a document that provides details of reinforcement steel required for a construction project.
BBS is prepared based on the structural drawings and specifications provided by the client or consultant.
It includes details such as the diameter and length of each reinforcement bar, the number of bars required, and the shape and size of the bar bends.
BBS helps in estimating the qua...
