DUS 1843:2017, Standard Test Method for Time of Setting of Concrete Mixtures by Penetration Resistance. (14 page(s), in English)

This Draft Uganda Standard covers the determination of the time of setting of concrete, with slump greater than zero, by means of penetration resistance measurements on mortar sieved from the concrete mixture. This test method is suitable for use only when tests of the mortar fraction will provide the information required. This test method may also be applied to prepared mortars and grouts. This test method is applicable under controlled laboratory conditions, as well as under field conditions.
