What is Slab Concrete Calculation? Slab concrete calculation is used to determine the quantity of cement, sand, and aggregate required for casting a slab. It helps engineers and contractors estimate materials accurately before construction work begins. Formula for Slab Concrete Volume Wet Volume = Length × Width × Thickness Dry Volume = Wet Volume × 1.54 For M20 mix ratio (1:1.5:3): Total Parts = 5.5 Cement = (1 / 5.5) × Dry Volume Sand = (1.5 / 5.5) × Dry Volume Aggregate = (3 / 5.5) × Dry Volume Example If slab size is 5m × 4m with 0.15m thickness: Wet Volume = 5 × 4 × 0.15 = 3 m³ Dry Volume = 3 × 1.54 = 4.62 m³ Use the calculator below to calculate exact material requirement.

  What is Plaster Quantity Calculation? Plaster quantity calculation is used to estimate the amount of cement and sand required for wall plastering work. It helps in proper material planning and cost estimation before starting site work. Formula for Plaster Calculation Step 1: Calculate area of wall Area = Length × Height Step 2: Calculate wet volume Wet Volume = Area × Thickness Step 3: Convert into dry volume Dry Volume = Wet Volume × 1.33 For 1:4 mix ratio (Cement : Sand) Total parts = 1 + 4 = 5 Cement = (1 / 5) × Dry Volume Sand = (4 / 5) × Dry Volume Example If wall size is 5m long and 3m high with 12mm plaster thickness: Area = 5 × 3 = 15 m² Wet Volume = 15 × 0.012 = 0.18 m³ Dry Volume = 0.18 × 1.33 = 0.239 m³ (approx.) Use the calculator below to instantly calculate cement and sand requirement. Plaster Quantity Calculator Wall Length (meters): Wall Height (meters): Plaster Thickness (mm): Calculate

  What is Brick Quantity Calculation? Brick quantity calculation is used to estimate the number of bricks required for wall construction. It helps in material planning, cost estimation, and reducing wastage at site. Formula for Brick Calculation Step 1: Calculate volume of wall Wall Volume = Length × Height × Thickness Step 2: Standard brick size (with mortar) ≈ 0.2m × 0.1m × 0.1m Brick Volume ≈ 0.002 m³ Step 3: Number of bricks Number of Bricks = Wall Volume / Brick Volume Example If wall size is 5m long, 3m high, and 0.2m thick: Wall Volume = 5 × 3 × 0.2 = 3 m³ Number of Bricks = 3 / 0.002 = 1500 bricks (approx.) Use the calculator below to instantly calculate required bricks. Brick Quantity Calculator Wall Length (meters): Wall Height (meters): Wall Thickness (meters): Calculate

What is M20 Concrete Mix Ratio? M20 grade concrete is one of the most commonly used concrete grades in construction. The standard nominal mix ratio for M20 concrete is: 1 : 1.5 : 3 (Cement : Sand : Aggregate) This means 1 part cement, 1.5 parts sand, and 3 parts aggregate are mixed to produce M20 grade concrete. How to Calculate Concrete Quantity? To calculate material quantity, first calculate wet volume of concrete: Wet Volume = Length × Width × Height Then convert wet volume into dry volume: Dry Volume = Wet Volume × 1.54 Material Calculation Formula Total parts = 1 + 1.5 + 3 = 5.5 Cement = (1 / 5.5) × Dry Volume Sand = (1.5 / 5.5) × Dry Volume Aggregate = (3 / 5.5) × Dry Volume Use the calculator below to instantly calculate material requirement for M20 concrete.

What is Steel Weight Calculation? Steel weight calculation is an important part of civil engineering and construction work. Before starting reinforcement work, engineers and contractors must calculate the exact weight of steel required for the project. This helps in cost estimation, material planning, and reducing wastage on site. Steel Weight Formula (D²/162) The standard formula used for calculating steel weight per meter is: Weight (kg/m) = D² / 162 Where: D = Diameter of steel bar in millimeters (mm) 162 = Constant value used in steel weight calculation Example Calculation Let’s calculate the weight of a 12mm diameter steel bar of 10 meters length. Step 1: Use formula → D² / 162 = 12 × 12 / 162 = 144 / 162 = 0.888 kg per meter Step 2: Multiply by total length = 0.888 × 10 = 8.88 kg So, total steel weight = 8.88 kg Why Steel Weight Calculation is Important? Accurate cost estimation Material procurement planning Prevention of steel shortage on site Be...
