Concrete Calculator Estimate Cement, Sand, Gravel

Concrete mix estimation. Our mix-on-site concrete calculation is based on batching by volume (Large construction sites employ batching by weight which is more exact). You can also estimate the quantity of sand and gravel required by weight; Simply multiply the volumetric quantity of sand and gravel with 1400 kg/m 3 (bulk density of sand) and 1600

How To Calculate Cement, Sand Aggregates Quantity in

03/08/2018  Consider volume of concrete = 1m3. Dry Volume of Concrete = 1 x 1.54 = 1.54 m3. Sand= (1.5/5.5) x 1.54 = 0.42 m3 ∴ 1.5 is a part of Sand, 5.5 is sum of ratio. Density of Sand is 1450/m3. For KG = 0.42 x 1450 = 609 kg. As we know that 1m3 = 35.31 CFT. For Calculation in Cubic Feet = 0.42 x 35.31 = 14.83 Cubic Feet.

How to Calculate Cement Sand and Aggregate Quantity

Dry volume of concrete = 1.54 (Volume increased by 54%) Why we take 54 %? The reason is dry aggregate, sand and cement contain air voids. Dry aggregate contains 33 to 34% air voids, whereas sand contains 20% air voids and cement contains very fine particles hence it contains negligible are voids so we can ignore it. Now add the air voids of sand and aggregate that are 20% +34% = 54% so

How much cement sand aggregate required for m25

M25 concrete mix ratio is 1:1:2, made of mixture of cement, sand and aggregate in which one part is cement, 1 part is sand and 2 part is aggregate or stone mix with water. 1m3 m25 concrete weight : unit weight of RCC is 2500kg/m3 and PCC is 2400kg/m3, so weight of 1m3 M25 concrete is 2500kgs when used as reinforced cement concrete and 2400kgs in plain cement concrete.

Calculate Quantities of Materials for Concrete -Cement

Cement = 1500 kg/m3 = 93.642 lb/ft3 = 2528.332 lb/cubic yards. Sand = 1700 kg/m3 = 105 lb/ft3 = 2865.443 lb/cubic yards. Coarse aggregates = 1650 kg/m3 = 103 lb/ft3 = 2781.166 lb/cubic yards. Specific gravities of concrete materials are as follows: Cement = 3.15. Sand = 2.6. Coarse aggregates = 2.6. The percentage of entrained air assumed is 2%.

Concrete Mix Ratios (Cement, Sand, Gravel)

Water/cement ratio theory states that for a given combination of materials and as long as workable consistency is obtained, the strength of concrete at a given age depends on the w/c ratio. The lower the w/c ratio, the higher the concrete strength. All materials used for a design including the water quality should be to a high standard. A general rule of thumb is, if the water is palatable then it is suitable for mixing concrete.

Concrete Mix Download Spreadsheet to Estimate

11/05/2016  To make concrete there are four basic materials you need: portland cement, sand, aggregate (stone), and water. The ratio of aggregate to sand to cement is an important factor in determining the compressive strength of the concrete mixture. The mixing process is the fact that the better you mix the concrete, the stronger it will be.
