Subject: Tests on the pressure of concrete..... Помогите, пожалуйста, перевести фразы:1)Tests on the pressure of concrete are difficult to manipulate because of the following. (1) The experimental height of 2.2 m for the pressure is not a commonly constructed height of wall. (2) In public works the height may vary between 4 m and 10 m, whereas it is better to use a uniform pressure. 2)It is important to note that the second case, with a total load of 90 kN/m², is unsatisfactory for formwork of 2.5 m to 3 m because of the type of load – the formwork will have the desired resistance but it will present deflections very different from the ones calculated with a triangular load. |
