An Investigation on Self-Compacting Concrete Using …

An experimental investigation was made on flow properties and compressive strength of self-compacting concrete (SCC) with ultrafine natural steatite powder (UFNSP) as replacement to cement. The tests were conducted on specimens with 5%, 10%, 15%, 20%, and 25% of replacement of UFNSP to the weight of cement …

Electrical Resistivity of Concrete for Durability Evaluation

7. Correlation between Electrical Resistivity and Compressive Strength. One of the most important mechanical properties of concrete is compressive strength. It can be simply measured by compression testing machine, as load at the failure divided by area of specimen gives the compressive strength of concrete . Thus, a number of researchers ...

Efficiency (statistics)

In statistics, efficiency is a measure of quality of an estimator, of an experimental design, or of a hypothesis testing procedure. Essentially, a more efficient estimator, needs fewer input data or observations than a less efficient one to achieve the Cramér–Rao bound.An efficient estimator is characterized by having the smallest …
