Concrete Mix Ratio Calculator – Cement, Sand & Aggregate Quantity Estimator The Concrete Mix Ratio Calculator helps civil engineers and contractors calculate the required quantity of cement, sand and aggregate based on mix ratio and total concrete volume. Concrete mix ratio such as 1:2:4 or 1:1.5:3 represents the proportion of Cement : Sand : Aggregate. Formula Used Step 1: Dry Volume = Wet Volume × 1.54 Step 2: Total Ratio = Sum of mix ratio numbers Step 3: Material Quantity = (Dry Volume × Individual Ratio) ÷ Total Ratio Common Concrete Mix Ratios M15 → 1:2:4 M20 → 1:1.5:3 M25 → 1:1:2 Concrete Mix Ratio Calculator Total Concrete Volume (Cubic Meter): Mix Ratio (Example: 1:2:4): Calculate Materials Frequently Asked Questions (FAQ) 1. Why is dry volume multiplied by 1.54? Dry volume is multiplied by 1.54 to account for bulking of sand and voids between materials. 2. What is the mix ratio for M20 concrete? The nominal mix ratio for ...

Brick Quantity Calculator – Estimate Number of Bricks for Construction The Brick Quantity Calculator helps civil engineers, contractors and site supervisors estimate the total number of bricks required for a wall construction project. Brick calculation is based on wall dimensions and standard brick size including mortar thickness. Proper estimation reduces material wastage and controls project cost. Formula Used in Brick Calculation Step 1: Calculate Wall Volume = Length × Height × Thickness Step 2: Calculate Single Brick Volume (including mortar) Step 3: Number of Bricks = Wall Volume ÷ Brick Volume Standard Brick Size (India) Brick Size (with mortar): 0.20 m × 0.10 m × 0.10 m Brick Quantity Calculator Wall Length (meters): Wall Height (meters): Wall Thickness (meters): Calculate Bricks Frequently Asked Questions (FAQ) 1. How many bricks are required in 1 cubic meter? Approximately 500 bricks are required in 1 cubic meter considering standard ...
