2010-12-09· Concrete prices can fluctuate regularly, based on the cost of the extraction of the components of concrete, and the cost of fossil fuels. At the time of writing, concrete costs about $90-$115 per cubic yard. 3000 psi concrete, which is the most commonly used grade, costs around $100-$110.This is just the cost of concrete itself, not including the various necessary peripheral processes.

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 kg/m 3 (bulk density of stone) respectively, when calculating in metric

Typical dosage of superplasticizers used for increasing the workability of concrete ranges from 1 to 3 liters per cubic meter of concrete where liquid superplasticizers contained about 40 % of active material. In reducing the water cement ratio, higher dosage is used, that is from 5 to 20 liters per cubic meter of concrete.

2014-11-15· The water in concrete has to perform the following two functions: (i) The water enters into chemical action with cement and this action causes the setting and hardening of concrete. (ii) The water lubricates the aggregates and it facilitates the passage of cement through voids of aggregates. This means that water makes the concrete workable.

While the cost of bag concrete is straightforward, the cost of ready-mix batch concrete is anything but. Even if your local batch company quotes a price of $100 per cubic yard, it still might refuse to sell you a single cubic yard without charging you a short load fee that could range from $50 to $200. Before ordering, ask the batch company representative about tack-on fees, which can include:
