This Draft Uganda Standard covers the determination of the resistance of concrete specimens to rapidly repeated cycles of freezing and thawing in the laboratory by two different procedures: Procedure A, Rapid Freezing and Thawing in Water, and Procedure B, Rapid Freezing in Air and Thawing in Water. Both procedures are intended for use in determining the effects of variations in the properties of concrete on the resistance of the concrete to the freezing-and-thawing cycles specified in the particular procedure. Neither procedure is intended to provide a quantitative measure of the length of service that may be expected from a specific type of concrete.

Products Covered: Refractory cements, mortars, concretes and similar compositions (excl. preparations based on graphite or other carbonaceous substances) (HS code(s): 3816); Refractory cements, mortars, concretes and similar compositions (excl. preparations based on graphite or other carbonaceous substances) (HS code(s): 381600); Non-refractory mortars and concretes (HS code(s): 382450); Articles of cement, concrete or artificial stone, whether or not reinforced (HS code(s): 6810); Concrete and concrete products (ICS code(s): 91.100.30)

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.

Products Covered: Concrete mixtures

This Draft Uganda Standard covers determination of the air content of freshly mixed concrete from observation of the change in volume of concrete with a change in pressure. This test method is intended for use with concretes and mortars made with relatively dense aggregates for which the aggregate correction factor can be satisfactorily determined by the technique described in Section 6. It is not applicable to concretes made with lightweight aggregates, air-cooled blast-furnace slag, or aggregates of high porosity. In these cases, Test Method C173/C173M should be used. This test method is also not applicable to non-plastic concrete such as is commonly used in the manufacture of pipe and concrete masonry units.
