Estimate the amount of material needed for your projects with our concrete calculator. Please enter the dimensions in the white fields below and click calculate to display the results. Volume of concrete required for 4 cubes = 4 x (0.153 x1.25) = 0.016878 m3, Cement = (383.2 x 0.016878) kg/m3 = 6.47 kg, Water = (191.6 x 0.016878) kg/m3 =3.23 kg, Coarse aggregate = (1087.75 x 0.016878) kg/m3 =18.36 kg, Fine aggregates = (800.94 x 0.016878) kg/m3 = 13.52 kg. See below for help on concrete. Coarse aggregate = 1087.75 kg/m 3. You can calculate the concrete mix ratio by entering the width, height and depth of the ratio in this concrete mix ratio calculator to know the total volume, sharp sand, gravel and water. Concrete Mix proportions for Concrete Trial Mix – 1. A reduction of 0.05 in w/c will entail and increase of coarse aggregate fraction by 0.01. Dry volume = Wet volume x 1.54 (You can also take it as 1.50 to 1.55, But it became standard practice to considering 1.54 as multiplication factor). Cement = 383.2 kg/m 3. A concrete mix ratio is usually expressed by a set of numbers separated by colons, as is the case with a 1:2:3 ratio. On-Site Concrete calculator. How to Inspect a Structure Using Acoustic Emission Testing? Types of Foundation for Buildings and their Uses [PDF], Calculate Quantities of Materials for Concrete -Cement, Sand, Aggregates, Methods of Rainwater Harvesting [PDF]: Components, Transport, and Storage, Quantity of Cement and Sand Calculation in Mortar, Standard Size of Rooms in Residential Building and their Locations, Mezzanine Floor for Buildings: Important Features and Types, Machu Picchu: Construction of the Lost City of Incas. As mentioned earlier to adjust fresh concrete properties the water cement ratio will not be changed. Target Mean Strength = 40 + (5 X 1.65) = 48.25 Mpa. Note 1: For every ±0.05 change in w/c, the coarse aggregate proportion is to be changed by 0.01. Cement = (384.8 x 0.016878) kg/m3 = 6.66 kg, Water = (197.4 x 0.016878) kg/m3 =3.33 kg, Coarse aggregate = (1073.33 x 0.016878) kg/m3 =18.11 kg, Fine aggregates = (790.3 x 0.016878) kg/m3 = 13.34 kg. Volume of coarse aggregate per unit volume of total aggregate = 0.62 x 90% = 0.558, Volume of fine aggregate = 1 – 0.558 = 0.442, b) Volume of cement = (Mass of cement / Specific gravity of cement) x (1/100), c) Volume of water = (Mass of water / Specific gravity of water) x (1/1000), d) Volume of total aggregates = a – (b + c ) = 1 – (0.122 + 0.1916) = 0.6864 m3, e) Mass of coarse aggregates = 0.6864 x 0.558 x 2.84 x 1000 = 1087.75 kg/m3, f) Mass of fine aggregates = 0.6864 x 0.442 x 2.64 x 1000 = 800.94 kg/m3. In the present example against mild exposure and for the case of reinforced concrete the minimum cement content is 300 kg/m3 which is less than 383.2 kg/m3. Sharp Sand = 120 x 600 Grade of concrete M20 (1:1.5:3) Find-out the Quantity of concrete (Wet volume and Dry volume) Wet volume of concrete = 1 m³.

Mean Design Strength3. In this case water / cement ratio is decreased by 10% keeping water content constant. Concrete Mix Design Calculation for M20, M25, M30 Concrete with Procedure & Example, Step 6: Estimation of the mix ingredients, Procedure for Concrete Mix Design of M25 Concrete. Mix is cohesive, workable and had a true slump of about 25 mm and it is free from segregation and bleeding. High Strength Concrete Mix Ratio; Different Grades of Concrete denotes its strength for required construction. Dry volume of concrete = 1 x 1.54 =1.54 m³ Cement = OPC 53 Grade, assume 7- Day compressive strength of Cement is 37 N/mm 2 Fck = 30 N/mm 2. Water Content and Air Content5. (e) Fine aggregates confirm to Zone II of IS – 383. For Calculate in CFT (Cubic Feet) = 8 x 1.225 = 9.8 Cubic Feet CALCULATION FOR SAND QUANTITY; Consider volume of concrete = 1m 3 . Self Mix Concrete Calculator - Metric Calculate the materials, including the amount of water needed, from a mixture ratio for on-site mixing of concrete. As per IS 456:2000 Standard Concrete grades are M 25, M 30, M 35, M 40, M 45, M 50 and M 55. Water = 191.6 kg/m 3. Our mix-on-site concrete calculation is based on batching by volume (Large construction sites employ batching by weight which is more exact). VIP members get additional benefits. Use this calculator to determine how much sand, aggregate (gravel) and cement is required for mixing on site a given area of concrete (1:2:4 ratio). Concrete Mix Ratio Calculator. The below mentioned method can be applied to any grade of concrete by changing the values. 2. Cement = 120 x 320 This value is to be checked for durability requirement from IS: 456. (a) Characteristic compressive strength required in the field at 28 days grade designation — M 25, (b) Nominal maximum size of aggregate — 20 mm, (d) Degree of workability required at site — 50-75 mm (slump), (e) Degree of quality control available at site — As per IS:456, (f) Type of exposure the structure will be subjected to (as defined in IS: 456) — Mild, (g) Type of cement: PSC conforming IS:455, (h) Method of concrete placing: pump able concrete. Dry Volume of Concrete = 1 x 1.54 = 1.54 m 3 Sand= (1.5/5.5) x 1.54 = 0.42 m 3 ∴ 1.5 is a part of Sand, 5.5 is sum of ratio . Water-Cement Ratio4. Hello Sir it wil be an honour if u explain the water cement ratio for m35 n m30 n how to design mix at wat ratio should I mix..for pile foundation of 1200 dia..n if sand is of … This tells the mixer that they need to add 1 part cement powder, 2 parts sand, and 3 parts aggregate in order to create the desired concrete consistency.
