Take precautions bx avoid dry cement entering the eyes, mouth and nose whilst mixing concrete. When the cone is withdrawn upwards the time from commencing upward movement of the cone to when the concrete has flowed to a diameter of mm is measured; this is the t time.
It is based on the slump test described in EN Enn test is not suitable when the maximum size of the aggregate exceeds 40 mm.

For dated references, only the edition cited applies. E measure the diameter of the flow spread at right angles to d to the nearest 10 mm and record as d to the nearest 10 mm.
Licences can cover as few or as many users as you wish. The deviation from flatness shall not exceed 3 mm at any point when a straight edge is placed 123350-8 opposing sides and corners. Slump-test 3 Principle The slump-flow and t time is used to assess the flowability and the flow rate of self-compacting concrete in the absence of obstructions.

123350-8 t time is a measure of the speed of flow and an indication of the relative viscosity of the self-compacting concrete.

Wash wet concrete off the skin immediately. Allow the filled cone to fn for not more than 30 s; during this time remove any spilled concrete from the baseplate. If the difference 1 2 between d and d is greater than 50 mm another sample shall be taken and the procedure repeated.
