COST (Concrete Optimization Software Tool) is an online design/analysis system to assist concrete producers, engineers and researchers in determining optimal mixture proportions for concrete.
With appropriate input from the user, COST uses statistical experiment design (DEX) principles to generate a set of trial batches (an experimental plan). The trial batches, which consist of batching, mixing, fabricating specimens, and performing necessary tests, are run by the user. The test results (data) can then be entered into COST for analysis and optimization.
Cost uses appropriate statistical analyses, both graphical and numerical, to assist the user in determining optimal mixture proportions to meet the particular project requirements.
There are two likely scenarios in which COST would be used:
COST requires the following input:
Material properties needed to determine mixture proportions and costs (specific gravities, absorption, cost, etc.)
