The phrase "average concrete" is correct and usable in written English.
It can be used to describe a standard or typical quality of concrete in construction or material science contexts.
Example: "The contractor recommended using average concrete for the foundation, as it meets the necessary strength requirements."
Alternatives: "standard concrete" or "typical concrete".
Sharifi (2012) studied the flexural behavior of SCC beams having an average concrete compressive strength of 30 MPa.
The average concrete compressive strength of the specimens in the test days was calculated by testing concrete cylinders for each concrete beam at the testing day.
The average concrete strength at the testing day of columns was 42.89 MPa, while the test of all columns had been carried out in two consecutive days.
A group of seven LVDTs was used at either end and on each side of the beam to measure smeared (average) concrete strains within the beam-web.
The average concrete cylinder compressive strength is 26.24 MPa to mimic a low value of strength-case of study for old-age structures in the local countries.
The average concrete compressive strengths of the tested specimens were relatively close to each other for the tested specimens and were equal to 31 MPa.
Average cylindrical concrete compressive strength (fcm) for the monolithic specimen, for beam and column precast elements, and the topping concrete were 37, 42, and 35 MPa at the test days.
On average, untreated concrete accumulated 11.3 grams of water.
Table 4 Average hardened concrete properties.
PVB composite produces low average density concrete of 1548 kg/m3 (96.6 pcf) and a compressive strength of about 40 MPa (5800 psi).
tau_{12}^{c} = frac{{sigma_{1}^{c} - sigma_{2}^{c} }}{{2 varepsilon_{1} - varepsilon_{2} )}}gamma_{12} (21)where ( sigma_{1}^{c} ) and ( sigma_{2}^{c} ) are the average (smeared) concrete stresses; ( varepsilon_{1} ) and ( varepsilon_{2} ) are the biaxial smeared strains in the 1- and 2- directions of the principal applied stresses, respectively.
