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 When the cone is withdrawn upwards the time from commencing upward movement of the cone to when the concrete has flowed to a diameter of mm is measured; this is the t time.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.

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.
