Conclusions
-
1.
The tensile strength of concrete increases with increase in the loading rate, the value of Kd.s being higher for saturated concrete than for dry.
-
2.
The limit of extensibility for dry and saturated concrete is the same and does not depend on the loading rate in the range 3–3000 kg/(cm2.sec).
-
3.
The magnitude of preliminary static compression of dry and saturated concrete does not affect the value of Kd.s. in tension.
